Tom Griffiths: 3 ways to make better decisions – by thinking like a computer March 8, 2020 bizadmin If you ever struggle to make decisions, here’s a talk for you. Cognitive scientist Tom Griffiths shows how we can apply the logic of computers to untangle tricky human problems, sharing three practical strategies for making better decisions — on everything from finding a home to choosing which restaurant to go to tonight. This talk was presented to a local audience at TEDxSydney, an independent event. TED’s editors chose to feature it for you. Books to Read Book The Most Human Human: What Artificial Intelligence Teaches Us About Being Alive Brian Christian Anchor, 2012 One concern I sometimes hear is that recognizing the parallels between people and computers might start to rob us of our humanity. Christian’s first book, The Most Human Human, is the perfect antidote to that. Participating in a Turing test, where he had to convince the judges that he was not a computer, led Christian to reflect on how intelligent machines can help us come to recognize what it is that makes us human. [abc] Book The Gardener and the Carpenter: What the New Science of Child Development Tells Us About the Relationship Between Parents and Children Alison Gopnik Picador, 2017 One of the big ideas in the talk is that understanding the trade-off between exploration and exploitation can help us understand how our approach to decision-making should change as we age. Alison Gopnik’s wonderful book explores this idea in more detail, making the argument that the very structure of human childhood is in part a consequence of navigating this trade-off. Book A Long Bright Future Laura Carstensen PublicAffairs, 2011 At the other end of the life span, Laura Carstensen tells us why we should be optimistic about old age. Book Algorithms Unlocked Thomas H. Cormen The MIT Press, 2013 For people who want to learn more about algorithms, this book does a great job of translating an undergraduate curriculum in computer science into a form that somebody with a little bit of mathematical background can easily appreciate. Book In Pursuit of the Traveling Salesman: Mathematics at the Limits of Computation William J. Cook Princeton University Press, 2014 Focusing on one problem in particular, this book is a great illustration of how computer scientists tackle the hardest computational problems — using approximations, shortcuts and a lot of ingenuity. Book Finite and Infinite Games James Carse Free Press, 2013 An inspiration for Algorithms to Live By, this book takes a single mathematical idea and then unpacks it into a manual for living a fulfilling life.

This Is How To Overcome Impostor Syndrome: 4 Secrets From Research January 17, 2020 bizadmin Barking Up The Wrong Tree Before we commence with the festivities, I wanted to thank everyone for helping my first book become a Wall Street Journal bestseller! To check it out, click here. This Is How To Overcome Impostor Syndrome: 4 Secrets From Research (Click here to read on the blog) Impostor Syndrome is like being a secret agent — in the most depressing way imaginable. No matter how hard you work, no matter how much you achieve, you still feel like a fraud. You still question your ability and you’re waiting to be exposed. More formally, it’s often referred to as “a failure to internalize success.” You attribute your accomplishments to luck or insane amounts of effort, but never talent or skill. Ask yourself these questions: [abc] From The Secret Thoughts of Successful Women: Why Capable People Suffer from the Impostor Syndrome and How to Thrive in Spite of It: Do you chalk your success up to luck, timing or computer error? Do you believe “if I can do it, anybody can”? Do you agonize over the smallest flaws in your work? Are your crushed by even constructive criticism, seeing it as evidence of your ineptness? When you do succeed, do you secretly feel like you fooled them again? Do you worry that it’s a matter of time before you’re “found out”? If you’re nodding your head, you’re not alone. 70% of people have felt it at one time or another — with some experiencing it chronically. And some very big names have been afflicted with it: Albert Einstein: …the exaggerated esteem in which my lifework is held makes me very ill at ease. I feel compelled to think of myself as an involuntary swindler. Maya Angelou: I have written eleven books, but each time I think, “Uh-oh, they’re going to find out now. I’ve run a game on everybody, and they’re going to find me out.” I can only dream that I will one day reach their level of astounding fraudulence. Jeez, look how inferior my fraudulence is to theirs. I’m a fraud at being a fraud… Seriously, there’s a lesson here: these two make it abundantly clear that no amount of achievement is going to convince you. That approach won’t work. And much of the advice we get isn’t helpful either. Merely “telling yourself you’re good enough” has all the scientific rigor of a Hallmark Card. Self-affirmations are as likely to cure this as they’d cure baldness. We need real answers, not platitudes. [abc] Funny thing is there’s a whole pile of scientific research that addresses this issue. It’s called “self-efficacy.” The concept was coined by Albert Bandura. He’s widely considered the most influential living psychologist and one of the most cited of all time. If there was a Mount Rushmore for psychology, his face would be up there. Bandura’s book is Self-Efficacy: The Exercise of Control. Now I hate when people use phrases like “learning your own value” because while it sounds really nice, nobody explains how to actually do it. Time to roll up your sleeves, bubba. We’re gonna fix that. Let’s get to it… So What The Heck Is Self-Efficacy? It’s “perceived ability to succeed at a given task.” It’s a belief, not an objective measure of ability. But it’s a thermonuclear powered belief and has an eye-popping effect on your life, whether you know what it is or not. From Self-Efficacy: Perceived self-efficacy refers to beliefs in one’s capabilities to organize and execute the courses of action required to produce given attainments… People’s beliefs in their efficacy affect almost everything they do: how they think, motivate themselves, feel, and behave. It can even be more important than skill. No doubt, actual skills are critical. If you have self-efficacy but no real driving ability, I’m not getting in your Uber. But that said, if you don’t believe you can accomplish something, you probably won’t try. And even if you do try, when you meet resistance, you’ll give up. [abc] And the effects of self-efficacy beliefs have been found in a staggering number of diverse arenas: academic grades, weight management, social behavior, health habits, occupational performance, etc. From Self-Efficacy: Where performance determines outcome, efficacy beliefs account for most of the variance in expected outcomes. When differences in efficacy beliefs are controlled, the outcomes expected for given performances make little or no independent contribution to prediction of behavior. “Oh, so it’s self-esteem and confidence.” That’s not what I said. Don’t put words in my mouth… Um, actually, I just put words in your mouth. ANYWAY, point is, self-efficacy is distinct from self-esteem and confidence, otherwise I promise I’d be writing a post on self-esteem and confidence because explaining new words is hard when old ones work fine. Self-efficacy is your belief about your ability to accomplish a specific goal while self-esteem is a judgment of personal worth. My self-efficacy about my ability to eat ice cream might be high, but I don’t think that makes me a good person. And confidence is more generalized, while self-efficacy is task-specific. You can be a very confident person and still not have self-efficacy when it comes to performing an appendectomy. So how does this relate to impostor syndrome? Well, impostor syndrome is fundamentally a belief issue. You could be saying, “I don’t have impostor syndrome, I actually suck at this and my results confirm that.” Instead, you’re saying, “I’m aware my performance is solid but I don’t believe it’s due to talent.” [abc] Impostor syndrome is about your lack of belief in your skill at something. Having self-efficacy is a healthy amount of belief in your skill at something. If we increase the latter, we get rid of the former. We need to get you to believe that your ability — not luck or mere hard work — is the primary active ingredient in your success. (To learn more about how you can lead a successful life, check out my bestselling book here.) So how do we do boost self-efficacy? Bandura lays out 4 things that will do the job. They all have big, fancy academic-sounding names that make my spellchecker go heavy on the red underlining. We’re gonna translate them in to English-that-people-actually-speak because I don’t like migraines any more than you do. Let’s start with the one that is, in general, most powerful… 1) Enactive Mastery Experience When most people perform well they attribute it to skill on their part. (Maybe they are too inclined to attribute it to personal skill, but that’s a topic for a different, much more cynical post.) [abc] But if you’re dealing with impostor syndrome, this natural tendency to assume you’re a virtuoso is on the fritz. You do a great job and the default attribution bucket isn’t a skill — it’s luck, overwork or invisible elves that accomplished everything while you were napping. Many interpret enactive mastery experience as “keep working hard and you’ll see it’s your natural ability that’s causing the results.” If that was true, impostor syndrome wouldn’t exist. In fact, if you don’t actively change your default attributions, merely seeing yourself succeed isn’t going to fix impostor syndrome — it’s going to make it worse. From Self-Efficacy: …the impact of performance attainments on efficacy beliefs depends on what is made of those performances. The same level of performance success may raise, leave unaffected, or lower perceived self-efficacy depending on how various personal and situational contributors are interpreted and weighted (Bandura 1982a). So what do we have to do? You need to notice the system you use. Your process. Yes, you have one. No, I have not been spying on you. You probably take it for granted. Or it’s a blur as you anxiously drive yourself crazy due to deadlines or trying to meet insanely high standards. It’s probably habitual at this point and therefore often subconscious, like driving a car, but there are things you do each and every time that are producing these consistently good results. (And if you’re not consistently getting good results then you don’t have impostor syndrome, and I’m not getting in your Uber.) Everyone does not do these things you do in your process and that’s one of the reasons not everyone gets the results you do. [abc] Look at the system as separate from you. Like the recipe that makes a good cake. When you have a solid recipe, or good instructions, you feel in control. And what’s control? It’s the exact opposite of luck. When you recognize that you have a system, and the system is producing those results consistently, the depressing magical thinking of impostor syndrome fades. You have a new “why” that’s responsible for those solid results. What would your reaction be if I told you, “I took 10 weeks of tennis lessons and my tennis luck increased dramatically!” You’d laugh. Systems and training don’t increase luck. They increase skill. You’re just not noticing or acknowledging the system you use. (And if I was your system I’d be pissed that Mr. Luck and Ms. Overwork were undeservedly getting all the credit around here.) When work is a blur it’s easy to think you just got lucky. But I’m guessing you’ve noticed that people who are very confident about their abilities can often explain them to you. They’re aware of their system. Step outside yourself and notice what you do that gets the results. As the great Carl Jung once said: “Until you make the unconscious conscious, it will direct your life and you will call it fate.” And what if that doesn’t convince you? Then set up an experiment. If you attribute your results to your lucky rabbit’s foot but you can repeatedly achieve the same results without it, then it’s hard to argue that dismembered mammal limbs are responsible for your success. From Self-Efficacy: When there is much subjectivity in judging the adequacy of one’s performances, as in social competency, an illusorily created low sense of efficacy endures despite repeated performance attainments that indicate personal capabilities (Newman & Goldfried, 1987). Dislodging a low sense of personal efficacy requires explicit, compelling feedback that forcefully disputes the preexisting disbelief in one’s capabilities. “Oh, I’m a fraud. I only do well because of hard work.” Fine. Set a time limit on how much effort you put in and see if the world comes crashing down. But before you start, think about your system and how you will do the things you always do in that shorter time frame. If you get 90% of your usual results in half the time, that’s not “hard work.” That’s talent. (To learn the two-word morning ritual that will make you happy all day, click here.) [abc] Okay, “enactive mastery blah bitty blah” is the method that works best in general. But what’s the method that works best for people who are unsure of themselves — like people with impostor syndrome? 2) Vicarious Experience In English: “Watching other talented people work.” If you’re reading this, you take your skills for granted. When you see that people who do similar things to you do well and a much larger group of people who do not do those things fail, you’ll realize your system works and there are other (inferior) methods that you’re choosing not to use. This means you have control. Control means not-luck. Problem is, when people with impostor syndrome look at others, they usually look at the wrong people. Often they compare themselves to people who have zero talent and have great difficulty finding their way out of the house every morning. Yeah, this makes you feel better but it doesn’t convince you you’re talented — it just means you’re not an idiot. Other times people with impostor syndrome compare themselves to the top 1% which acts as a fast-acting injection of depression concentrate and is utterly debilitating. Instead, think Goldilocks: you’re not looking to compare yourself to “too cold” or “too hot”, you’re looking for “just right.” Bandura says you’ll get the best results by observing others who are your peers or slightly better than you. [abc] From Self-Efficacy: Persons who are similar or slightly higher in ability provide the most informative comparative information for gauging one’s own capabilities (Festinger, 1954; Suls & Miller, 1977; Wood, 1989). How does this help? Plain and simple: it’s inspiring. “If they can do it, I can do it.” They have a system. It works. You have a system (if you take the time to notice it) and it works. You’ll probably see what they do is pretty similar to what you do. You both get good results and you’re peers. It’s not luck. You can even leverage vicarious experience without the vicarious part: it’s called “self-modeling.” Watch yourself working successfully. Look at good work that you’ve done. Smart emails you’ve sent. Great presentations or reports you’ve put together. Anything that resonates with you and makes you say, “Hey, this is impressive work — oh, and I’m the one who did it.” From Self-Efficacy: Self-modeling has remarkably wide applicability and often succeeds with inveterate self-doubters where other instructional, modeling, and incentive approaches fail (Dowrick, 1991; Meharg & Wolterdorf, 1990). Apparently, it is hard to beat observed personal attainment as a self-persuader of capability. Let your “best self” be your role model. (To learn how to deal with passive-aggressive people, click here.) We don’t just want to watch others work, we also want to get help from our friends. But the trick is getting the right kind of support that will kill your impostor syndrome and not increase it… 3) Social Persuasion Translation: support and encouragement. For people who have impostor syndrome, simply seeing results isn’t enough to boost belief in their ability… but seeing results and having others praise them does the trick. From Self-Efficacy: …skill transmission and success feedback alone achieved little with individuals beset with strong doubts about their capabilities. But skill transmission with social validation of personal efficacy produced large benefits. Tell your friends you’re going through a tough time and could use their support. There are three tips from the research you’ll want to keep in mind here: [abc] 1) If the positive feedback is insincere, you’ll see right through it thanks to the negative, skeptical lens of impostor syndrome. It has to be legit praise. 2) Support from experts is preferable. Praise from someone who doesn’t understand the arena is easily dismissed. 3) Positive feedback about your hard work is nice but them praising your ability is better. If you keep getting praised for your hard work, it’s easy to conclude that you don’t have talent. From Self-Efficacy: Evaluative feedback highlighting personal capabilities raises efficacy beliefs. Feedback that the children improved their capabilities through effort also enhances perceived efficacy, although not as much as being told that their progress shows they have ability for the activity. You don’t want white lies about your lightsaber abilities, you want sincere compliments. And you’d like them from Yoda. And it’s nice to hear you worked hard but it’s better to hear, “The Force is strong with this one.” (To learn the 4 harsh truths that will make you a better person, click here.) We’ve covered systems, models, and support. What’s left? Oh, feelings. You can never get away from the power of feelings, like it or not… 4) Emotional / Physiological States Your feelings and moods matter. And if you think they don’t matter then you’re in real trouble because they’re still influencing you and you’re not even noticing it. Not getting enough sleep, being hungry or just having a bad day can exacerbate impostor feelings, but unless you take the time to establish those are the underlying causes, you’re just going to feel awful and default to blaming yourself for being a fraud. [abc] From Self-Efficacy: Mood activates the subset of memories congruent with it through an associative mood network. Thus, a negative mood activates thoughts of past failings, whereas a positive mood activates thoughts of past accomplishments… According to Teasdale (1988), negative episodes and depressed mood activate a global view of oneself as inadequate and worthless rather than just activating unhappy memories. Here’s the problem: we are absolutely terrible at figuring out the true causes of our feelings. You think you know why you’re feeling something but it’s just inference. You think you’re cranky because of what your partner said but it’s actually because you’ve been running on five hours of sleep for the past three nights. But here’s the upside: you can now use your knowledge of this emotional blurriness to your advantage. Since the cause and meaning of feelings is all about interpretation, you can choose to interpret them differently. The court of emotions has an appeals process. If you can reframe the feelings into something transient or unrelated to the task at hand then your self-efficacy doesn’t plummet. From Self-Efficacy: …if the meaning of an affective state is altered by attributing it to a nonemotional or transient irrelevant source, the state does not affect evaluative judgment because it is considered uninformative for the judgment at hand. For example, interviewers who attribute their accelerated heart rate to having rushed up a set of stairs are less likely to wonder about their capabilities to manage the interview situation than interviewers who read their pounding heart as a sign of distress. Yes, you’re fidgety before the big meeting. But that physical feeling has to be interpreted. You don’t have to believe it’s nervousness because you’re a faker. It could be excitement or anticipation. Reframe your feelings and you can reframe impostor syndrome… and that can reframe your life. [abc] (To learn more about how to make friends as an adult, click here.) Okay, we’re all Bandura’d out. We covered a lot, time for the sum up — and we’ll also answer the looming question: even if you beat impostor syndrome today, how do you know that this newly found self-efficacy will last? Sum Up This is how to overcome impostor syndrome: Enactive mastery experience: Recognize your system. Tennis lessons don’t increase tennis luck. Vicarious experience: If they can do it, you can do it. Social persuasion: I, for one, happen to think The Force is very strong with you. So there. Emotional/physiological states: Reframe feelings. You’re not antsy because you want this blog post to end, you’re just so very very excited to be reading it. People are afraid that even if they develop self-efficacy they’ll backslide into impostor feelings. Don’t worry. If you really go out of your way to push hard on the 4 principles above, self-efficacy can become as stubbornly lodged in your brain as the feeling that you’re a fraud is now. I don’t know about you but I’m all for positive feelings that are irrationally resistant to change. [abc] From Self-Efficacy: They continue to adhere to the fictitiously instilled efficacy beliefs even after the persuasory basis for those beliefs has been thoroughly discredited. Efficacy beliefs created arbitrarily survive behavioral experiences that contradict them for some time (Cervone & Palmer, 1990). Lawrence (1988) provides suggestive evidence that efficacy beliefs created by fictitious success may gain strength through a cognitive self-persuasion process. The old saying is “fake it till you make it.” But with impostor syndrome, you’ve already made it. The race is over. You won.

The Rabbit Effect: Live Longer, Happier, and Healthier with the Groundbreaking Science of Kindness November 15, 2019 bizadmin Author(s): Kelli Harding M.D. M.P.H Release Date: August 27, 2019 Publisher/Imprint: Atria Books Pages: 256 Buy on Amazon Note: I was reading and surfing around when I came across this marvelous book on Groundbreaking Science of Kindness, of the Rabbit Effect. Below is the review by Lloyd Sederer: “beautifully identifies kindness as an endlessly renewable resource—the light we all can shine on the lives of others and in so doing bathe in its grace ourselves.” We all would be fortunate to have Kelli Harding, MD, MPH as our doctor. That’s because she comprehends the power of the interplay of body, mind, and social circumstances: the behaviors we engage in; the environments we inhabit; the kindness or cruelty that characterize our relationships; the adequacy or inadequacy of our income; our housing stability and the security of our next meal; education—learning to be more exact; and purpose in work and meaning in life—the factors that principally determine the degree to which we will enjoy good health or disproportionately suffer from the ailments that beset the human race. If that sounds like a lot, that’s because it is. But it’s not rocket science; instead, it’s the science of wellbeing, and what that requires of us. Dr. Harding terms many of the drivers of health and disease “the hidden factors.” Not because they are undiscoverable but because we tend not to recognize them, nor give them their due. Yet, as she so kindly and clearly writes, her aim is to reveal these factors both to her patients and to her readers because therein lie the ways we can pursue and achieve greater wellbeing, and not passively accede to illness and despair. The Rabbit Effect is not the usual self-help, list of to-dos. After a medical residency at New York’s Mount Sinai hospital and a psychiatric residency at Columbia, Dr. Harding must have known she needed to know more. There was still too much mysterious and elusive about our lives. Too many “inconsistencies,” not enough explanatory power in (even the vastness of) today’s biomedical enterprise. She wondered what the “hidden factors” in health and illness are and which are ubiquitous but effectively generally lost to the ministrations of conventional medical care. Dr. Harding stayed on at Columbia to take a National Institute of Mental Health (NIMH) Fellowship, with a particular focus on unexplained symptoms. She trained, as well, in the psychiatric sub-specialty of psychosomatic medicine—where mind and body blend into the whole that more fully defines us. Her epiphany came, as the book title portrays, from the rabbits. Arthur Barsky, MD, her fellowship mentor (and a former colleague of mine at Massachusetts General Hospital), pointed her to some rabbit studies. Certain white rabbits, like humans, are prone to develop heart disease if they are fed a high-fat diet (like fried foods and red meat). The rabbit research she then discovered, thanks to her mentor, revealed the relationship between high cholesterol and heart disease. Curiously, one group of rabbits exposed to the same cholesterol loads had 60% fewer fatty deposits than the others. Many great discoveries occur when an investigator, instead of dismissing an aberrant finding, chases after its meaning. Those who disdain “touchy-feely” explanations will meet their nemesis in this group of white rabbits. Why were they spared the cardiac artery fatty deposits that interfere with blood flow and increase the risk of heart disease and myocardial infarction? Turns out this particular colony of rabbits was cared for by a wonderfully nurturing graduate student. Could kindness explain their having been better safeguarded from disease? The research group then replicated the study, not by happenstance as it had occurred, but by design. Their findings appeared in Science. Unhealthy life experiences, their work implied, could be mitigated by affection and nurturance. Dr. Harding’s professional course was now struck. The “hidden factors” were staring us in the face if only we designed to look. This takes us full circle to her book, The Rabbit Effect: Live Longer, Happier and Healthier with the Groundbreaking Science of Kindness. The book has two principal sections, namely The Hidden Factors and Essentials of Health. Healthy relationships (trustworthy and enduring attachments) and social ties through our friends and community lead off her discussion of the factors hidden in plain sight. Work defines us, as well, especially if we have the good fortune to find meaning and contribution to what we do. As does discover and pursuing our purpose; she quotes the Buddha who said, “Your purpose in life is to find your purpose and give your whole heart and soul to it.” Drawing on the work of Nobel Laureate, Dr. Elizabeth Blackburn, Dr. Harding, our caring guide, highlights how the length of our telomeres (where longer is far better), the protective caps on every DNA strand in our bodies, are shortened by a life of stress. The natural or stress-induced shortening of telomeres is spared by purpose (and a healthy lifestyle) which mitigates the effects of stress. The result is longer, healthier lives. All of these hidden factors, well explained by Dr. Harding, are topped off (in the last chapter in this section) by a life in which fairness prevails (so often denied to those living in poverty or racial/ethnic discrimination) and compassion rules. The best evidence for compassion, ironically, derives from those children who are traumatized by its opposites, namely neglect, physical and sexual abuse, domestic violence, parental incarceration or active substance abuse, to name a few. These are now famously understood, yet poorly prevented and treated; they are called Adverse Childhood Experiences (ACEs). Each chapter on the hidden factors ends with what our physician guide calls “Expand Your Toolbox.” She offers clear and feasible ways by which any of us can strengthen our attachments and social ties, alter our experiences of work, or practice fairness and compassion. Her toolboxes are not prescriptive or preachy; they offer the kind of do-able and wise solutions that make for a better life. The final section of this book is about the Essentials of Health. Here Dr. Harding digs into her training and experience as a psychosomatic and public health doctor (that’s the MPH she lists after her MD). She illustrates the deep connections between stress—and the inflammatory response it evokes—and our physical and mental health. Attention to diet, sleep, exercise, a variety of mind-body activities (like meditation, yoga, slow breathing, mindfulness) and finding and sustaining caring relationships are the royal yet truly pedestrian roads to longevity and wellbeing. Gratitude is another means of reinforcing the “rabbit effect;” it is a practice that can simply be adopted by ending each day with a list of those people whose effect on you was beneficial—and to whom you owe gratitude (even if unspoken, as in a notebook). And the last chapter takes us from the individual to the collective—to the community of others around us, where trust and humanity are built one person, one encounter at a time. We are all in this world and life together. This review would be incomplete without noting the book’s Conclusion. And we are back to the lessons we need to learn from the care of the white rabbits. Dr. Harding leaves us with the greatest of kindnesses, namely urging us to find opportunities to provide moments of kindness. To those we love and to those who are part of our communities, small and large. Random acts of kindness are fine too! She quotes Ben Franklin, who reportedly asked, every day, “What good can I do today?” She beautifully identifies kindness as an endlessly renewable resource—the light we all can shine on the lives of others and in so doing bathe in its grace ourselves. __________________________________________________________ Lloyd Sederer, MD, is Medical Editor for Mental Health for The Huffington Post, Adjunct Professor at the Columbia/Mailman School of Public Health, and Chief Medical Officer for the NYS Office of Mental Health.

The Elements of Statistical Learning: Data Mining, Inference, and Prediction, Second Edition (Springer Series in Statistics) 2nd Edition April 12, 2019 bizadmin For those who love science and mathematics, then this is the book for your reading from Amazon. Some of the chapters include Bootstrap versus Maximum Likelihood, Trees with Simulated Data, Model Averaging and Stacking, etc. It may sound alien to most of us but for the learned, this makes an interesting read, especially for those who are doing their masters or PhDs. The Elements of statistical learning is more for actuarial science students who will later work in the insurance industry, calculating complex data and refunds to the policy holders. Some Reviews include the below: Very comprehensive, sufficiently technical to get most of the plumbing behind machine learning. Very useful as a reference book (actually, there is no other complete reference book). The authors are the real thing (Tibshirani is the one behind the LASSO regularization technique). Uses some mathematical statistics without the burdens of measure theory and avoids the obvious but complicated proofs. I own two copies of this edition, one for the office, one for my house, and the authors generously provide the PDF for travelers like me. The author’s biography includes those from Wikipedia: Biography Robert Tibshirani (born July 10, 1956) is a Professor in the Departments of Statistics and Health Research and Policy at Stanford University. He was a Professor at the University of Toronto from 1985 to 1998. In his work, he develops statistical tools for the analysis of complex datasets, most recently in genomics and proteomics. His most well-known contributions are the LASSO method, which proposed the use of L1 penalization in regression and related problems, and Significance Analysis of Microarrays. He has also co-authored three well-known books: “Generalized Additive Models”, “An Introduction to the Bootstrap”, and “The Elements of Statistical Learning”, the last of which is available for free from the author’s website.

The Lean Startup Book from Amazon April 2, 2019 bizadmin Today, I am going to introduce a book from Amazon: The Lean Startup: How Today’s Entrepreneurs Use Continuous Innovation to Create Radically Successful Businesses in Hardcover. It is authored by Eric Ries and is a bestseller on the e-commerce platform. Most startups fail. But many of those failures are preventable. The Lean Startup is a new approach being adopted across the globe, changing the way companies are built and new products are launched. Eric Ries defines a startup as an organization dedicated to creating something new under conditions of extreme uncertainty. This is just as true for one person in a garage or a group of seasoned professionals in a Fortune 500 boardroom. What they have in common is a mission to penetrate that fog of uncertainty to discover a successful path to a sustainable business. The Lean Startup Startup offers companies that are both more capital efficient and that leverage human creativity more effectively. Inspired by lessons from lean manufacturing, it relies on “validated learning,” rapid successful startups, as well as a number of counter-intuitive practices that shorten product development cycles, measure actual progress without resorting to vanity metrics, and learn what customers really want. It enables a company to shift directions with agility, altering plans inch-by-inch, minute by minute. Rather than wasting time creating elaborate business plans, The Lean Startup offers entrepreneurs – in companies of all sizes – a way to test their vision continuously, to adapt and adjust before it’s too late. Ries provides a scientific approach to creating and managing successful startups in an age when companies need to innovate more than ever.

Inspired by lessons from lean manufacturing, it relies on “validated learning,” rapid scientific experimentation, as well as a number of counter-intuitive practices that shorten product development cycles, measure actual progress without resorting to vanity metrics, and learn what customers really want. It enables a company to shift directions with agility, altering plans inch-by-inch, minute-by-minute. Rather than wasting time creating elaborate business plans, The Lean Startup offers entrepreneurs – in companies of all sizes – a way to test their vision continuously, to adapt and adjust before it’s too late. Ries provides a scientific approach to creating and managing successful startups in a age when companies need to innovate more than ever.

Good to Great: Why Some Companies Make the Leap and Others Don’t March 2, 2019 bizadmin Good to Great seems to be an interesting read in your spare time or bedtime. You cannot ignore this book if you own a company and are struggling to run it; be it financial issues or employee-employer issues, etc. Many of the rich people spend at least 2 hours each day reading a book and Bill Gates is known to read many books a year! We learn from the great authors with experience and tap into their brains. Here’s a summary of the book: The Challenge: Built to Last, the defining management study of the nineties, showed how great companies triumph over time and how long-term sustained performance can be engineered into the DNA of an enterprise from the very beginning. But what about the company that is not born with great DNA? How can good companies, mediocre companies, even bad companies achieve enduring greatness? The Study: For years, this question preyed on the mind of Jim Collins. Are there companies that defy gravity and convert long-term mediocrity or worse into long-term superiority? And if so, what are the universal distinguishing characteristics that cause a company to go from good to great? The Standards: Using tough benchmarks, Collins and his research team identified a set of elite companies that made the leap to great results and sustained those results for at least fifteen years. How great? After the leap, the good-to-great companies generated cumulative stock returns that beat the general stock market by an average of seven times in fifteen years, better than twice the results delivered by a composite index of the world’s greatest companies, including Coca-Cola, Intel, General Electric, and Merck. The Comparisons: The research team contrasted the good-to-great companies with a carefully selected set of comparison companies that failed to make the leap from good to great. What was different? Why did one set of companies become truly great performers while the other set remained only good? Over five years, the team analyzed the histories of all twenty-eight companies in the study. After sifting through mountains of data and thousands of pages of interviews, Collins and his crew discovered the key determinants of greatness — why some companies make the leap and others don’t. The Findings: The findings of the Good to Great study will surprise many readers and shed light on virtually every area of management strategy and practice. The findings include: Level 5 Leaders: The research team was shocked to discover the type of leadership required to achieve greatness. The Hedgehog Concept: (Simplicity within the Three Circles): To go from good to great requires transcending the curse of competence. A Culture of Discipline: When you combine a culture of discipline with an ethic of entrepreneurship, you get the magical alchemy of great results. Technology Accelerators: Good-to-great companies think differently about the role of technology. The Flywheel and the Doom Loop: Those who launch radical change programs and wrenching restructurings will almost certainly fail to make the leap. “Some of the key concepts discerned in the study,” comments Jim Collins, “fly in the face of our modern business culture and will, quite frankly, upset some people.” Perhaps, but who can afford to ignore these findings?
