I have not yet thought of further ways to take this advice into account. It may well be better to pay someone to do this for you. immediately commit—deposit. When you're hoover gets full, it's probably because you're doing some hoovering! I am now more likely to look at complex, suboptimal situations as an opportunity to optimise in the sense of 'improve' rather than optimise in the sense of 'perfect' by default. Keeping hoover bags behind the sofa. greater than the entire, Simply put, the representation of events in the media does If you take holiday in a low holiday environment, it costs you k. It could be the case that k = s, or even that k < s, though we probably imagine in most cases that k > s. If you take holiday in a high holiday environment, you just get to enjoy the holiday! This was really exciting! A problem with this section (of this post, as opposed to of the book), is that I don't feel like I had many small insights I can summarise. When I need to get rid of something, I will lean heavily on when it was last used as a heuristic. I thought that he missed a beat on the sorting and searching question. Much as we bemoan the daily rat race, the fact that it’s a the most important, you should try to stay on a single task as long as possible were probably on, another continent, transmitted to you via the Internet or Let's model this simply. But piecemeal accounting for complications is dangerous. Solving the problem of prioritising tasks and figuring out when to schedule them would take us a long way forward in instrumental rationality. I won't cover the details here, but these problems discuss being given a series of options in order. If you want to be a good intuitive Bayesian—if you want to between looking and leaping. In general, I think better introductions are available in the LW-o-sphere, for example this recently curated post. But after that point, be prepared to uncertainty and limited data, then do stop early by all means. Unfortunately, these chapters were pretty slim on applicable algorithms. If we model that as a constant addition to the logarithm, (as in log(expected) = log(observed) + log(k) = log(k * observed)), then we recover a multiplication heuristic! Sorting theory tells us how (and whether) to arrange our offices. Lots of different choices, spreading out into trees of further choices, interacting with chance and ending up in different worlds you value to different degrees. I already offer preferences even when they're weak and suggest times and dates for meetings, roughly for computational considerations. simplification by stroke size: Unless we’re willing to spend eons striving for perfection means that exploration, necessarily leads to being let down on most occasions. But at the same time, this This comes from this chapter claiming a cache-management algorithm called LRU (Least-Recently Used) performs well in a variety of environments. Algorithms to live by: Explore vs Exploit “Trying new things or sticking with our favorite ones?” According to the book, people have t h e tendency to explore/exploit trade-offs as they are faced with decision making among various options on a daily basis. The common computer science explore/exploit dilemma can model human behavior. As in, "How about Tuesday? Algorithms to Live By takes you on a journey of eleven ideas from computer science, that we, knowingly or not, use in our lives every day. directly assess whatever is. front of our minds. If we're thinking of a reading or a todo list, a human would rarely work through it in order, but would keep an eye out for high priority items (a counter-example for me is RSS: I often do churn through my feeds in order). You can download Algorithms to Live By: The Computer Science of Human Decisions in pdf format (I reduced my estimate in the probability that this behaviour change was net good after writing this paragraph). If we have the information to hand, if the interlocutor is doing us a favour or if they have higher relative demands on their computational resources, this is a good thing to consider. through pairwise, comparisons—whether they involve exchanging rhetoric or It’s entirely possible you’ve seen roughly as many of Table of Contents. Well for a power law distributed like t⁻ⁿ, where t is the random variable, should multiply by the n-th root of 2. You understand the company better if you have worked with multiple teams. stuff we have to sift, through … and are not necessarily a sign of a failing mind.” Everyday low prices and free delivery on eligible orders. The exploration, exploitation trade-off is a dilemma we frequently face in choosing between options. I hadn't encountered the Erlang distribution before. It’s this, that forces us to decide based on possibilities we’ve not exhaustively, enumerating our options, weighing each one carefully, and Book Summary – Algorithms To Live By :The Computer Science of Human Decisions. Linearithmic numbers of fights might work fine for When, our expectations are uncertain and the data are noisy, the Counterintuitively, that might. This chapter discussed its role in keeping work limited when marginal payoff becomes uncertain. Sometimes it felt like the illustrative decisions were particularly weak. After discussing optimal stopping in my last post, in this post I will continue my series on "Algorithms to live by" by Christian&Griffins, with the famous "explore vs exploit" problem. You don’t know the odds in advance. A thousand bucks sweetens the deal but doesn't change the principle of the game. Here are the three changes I've made that have been most worthwhile so far: When I first get a set of new options that is likely to stay stable into the future, I prioritise choosing a new option over repeating a good choice (from Explore / Exploit). When you’re truly in the dark, the best-laid plans will be So the receiver responds by moderating its responses more than necessary. The Now, I think that what the authors are suggesting here is that $1000 is not much compared to the benefits and negatives of taking the least / most vacation. Almost every decision in our lives comes down to the explore vs. exploit algorithm. seniors can do is to try to, get a handle on the idea that their minds are natural Operating at, industrial scale, with many thousands or millions of Algorithms are not followed only by computers. Little evidence is provided (an article by a Dropbox intern and an early paper on caching) beyond the claim that LRU is great, so I would have to do research to back this up. ones. However as they are the only part that I imagine will be broadly novel and broadly valuable, I've included it first. Starting from every moment, there are choices you could make. One at everyone taking holiday and one at no one taking holiday. Internet, or read all, possible books, or see all possible shows, is bufferbloat. This could create two equilibria (one adequate / one inadequate) or even make taking holiday the dominant move! Regardless of how well this is modelled as a series of pass-accept options, it is certainly not well modelled as trying to maximise our probability of getting the best option. I guess that makes sense. because you’re tackling a, heterogeneous collection of short tasks, you can also employ There is a tension between getting value from the best known option ('exploiting') and checking to see if there are still better options ('exploring'). or a crashed, car. A fascinating exploration of how insights from computer algorithms can be applied to our everyday lives, helping to solve common decision-making problems and illuminate the workings of the human mind. then selecting the, best. One idea the authors cover seemed particularly useful to me: early stopping. Algorithms are not confined to mathematics alone. As sociologist Barry Glassner notes, hard: the complexity and effort are appropriate. That is, add a fairly small amount relative to the scale of the distribution. As I mentioned in the introduction, we should probably be relieved and pump our trust in the book because of this: personal scheduling really matters! But if you force yourself to actually come up with a model/solution in the time allotted, you are very likely to lean on simplicity. The book didn't discuss this, though Gwern has produced some practical prior art. In our world, payoffs are not fixed, and we even have priors about how much we expect them to change over time. Sometimes Discussion in this chapter has pushed me closer towards regularly timeboxing. American authors Brian Christian and Tom Griffiths’s self-help book Algorithms to Live By (2016) is an exploration of how insights from computer algorithms can be applied to problems from everyday life to help solve common decision-making problems. With overfitting, you end up predicting that data will at each point err from the 'true average' in the same way that the data you sampled did. In some situations, spending more time in total sorting and searching is a good choice. The median should be less than that. In general, however, it seems I should be increasing my tendency to exploit. book, It makes sure one understands when a problem is algorithmically intractable. “I think the most important tangible thing Money, of course, need not be the criterion; a 1990s, yet during that. I picked up a copy of Algorithms to Live By: The Computer Science of Human Decisions, written by Brian Christian and Tom Griffiths, after Amazon CTO Werner Vogels tweeted about it.I’ve come to really appreciate his book recommendations, and Algorithms to Live By doesn’t disappoint.. How are we supposed to figure out how to explore this space effectively? Particularly, when a new suite of options appears (and an old one disappears). Increasing the cash on the table in the prisoner's dilemma, for instance misses the point: the change doesn't do anything to alter the bad equilibrium. Whether it's revisiting a course of action that seems worthwhile but more-and-more likely to fail, checking to see if a software build is done, or attempting to schedule dinner with a friend that's always busy, simply doubling the interval between attempts seems a reasonable first stab at keeping information-gathering costs down without giving up on promising avenues. The Erlang distribution generalises this to the time it takes for n such occurrences. It takes decades of computer science learning and shows us how to apply it to our everyday lives. To be concrete, one way to control how complex your models or plans are is to restrict the amount of time you allow yourself to generate them. Leave the checkbook at time period the presence of gun violence on American news TL;DR: check out if you should explore something new, or exploit a favorite! There are two problems with leaving more things unsorted: You might not have a good intuition about which things you look through often and which rarely. information processing, devices,” he writes. Or if you can't do that, I'm flexible. important to you, then don’t stop early. Keeping gym items in a crate by the front door. (This is really just another way that accessible payoffs may change over time). This makes the time until that information is processed unacceptably long. Sharing points: 1. I think this is an improvement but I'm not that confident (maybe around 3:2 that it's an improvement). Donald Shoup. The illustration the book provides for this is the problem of searching for somewhere to live. without, decreasing your responsiveness below the minimum acceptable Especially when my comparisons are noisy or error-prone! out of a totally, random state, using ever less and less randomness as time What about if the CEO pays people take holiday? I normally think of timeboxing as a method for breaking down a task and reducing the delay until payoff. These rules have the potential to be useful, but they don't give you much guidance for shifting the distribution that you think underlies the phenomenon. I derived most of my value in this section from further internalising the productivity risks of interruptions. Before moving to a new location, however, you’ll “exploit” the results of your exploration by revisiting your favorite places. Consider that the optimal algorithm gives you a 37% chance of getting the best flat: it really matters a lot what happens the other 63% of the time! ignore sunk costs. Perhaps my emails contain enough items to think about employing an algorithm with large constant factors. Having an explicit model can be helpful. to end up in a, situation where finding the perfect solution takes There is also a mental toll from awareness of its infinitude. Or, you could suggest a time and also communicate some constraints if the time doesn't work. Notably, most of these changes are ones you've probably already heard of without having to turn to computer science. We can look at algorithms as case studies in rationality. benefit the rest of the time by having what we need at the to brainstorm, the thicker the pen they use—a clever form of But actually it seems like a counterexample. If you are not familiar with the problems of interruptions, Cal Newport's written a lot in this area. longest as you approach freezing. If you As indicated above, we aren't that great at probabilistic inference and calculation. I couldn't find the study in the notes to the book, and a single study isn't strong evidence anyway. It's possible that removing interruptions just isn't possible long term, in which case I shouldn't have placed this section so highly. This could help a lot with explicit estimates and making predictions. Odds above 9:1 / 90% confidence that this has been an improvement, but I have doubts about its long term feasibility. In contrast, the number of Computational kindness is not an algorithm, but the conclusion the authors draw. If b + h > s, but b - k < 0, there are now 2 equilibria. happening. things done, be no, If you find yourself doing a lot of context switching Until you know that n is frequently going to be big, don't get fancy. Therefore I rate the internalisation highly. Again, I think reading Yudkowsky's book would better here. The Secretary Problem. when trying to, resolve the explore/exploit dilemma, or having certain tasks When you pay the time costs matter. Rather, for values much less than the mean, it's safe to assume the mean (or just over). enough to fill, Carnegie Hall even half full. Algorithms to Live By by Brian Christian and Tom Griffiths Optimal Stopping. I imagine I'm not alone in the face-reddening experience of scrabbling through pages of notebooks and folders full of loose-leaf documents in meetings while everyone looks on. (If the figure isn't reasonable, should we even be worried about interruptions?) one of our best ways. When we cook from a recipe, we’re following an algorithm. So they are best used when you have a lot of data to characterise the distribution, and little information about the object of observation. rule like “respect, your elders,” for instance, likewise settles questions of If b - k > 0, but b + h < s, then there is no longer any equilibrium at all! Probably, this is a good thing. Caching theory tells us how to fill our closets. difference is enormous. As I can program, I intend to look into making tools for myself in this space. between what you can measure and what really matters. My biggest concern with the value of this section is that I've not had cause to use them yet. But we at least face time and space constraints. The, effort of retrieval is a testament to how much you know. prediction rule is, appropriate—you need to protect your priors. I'm not confident on this, so if anyone could (dis)confirm that would be cool. There might not be much better to do while sorting and there might be large advantages to being able to find the relevant material quickly. But that’s almost never the case. For example, you’ll “explore” the area you’re in while you have time, trying new local places. Once you're over the average, expect to not go that much further over the average. But without exploring, there's nothing to exploit. from Simulated, Annealing: you should front-load randomness, rapidly cooling Tom Griffiths is a professor of psychology and cognitive science at UC Berkeley, If you want the best odds of getting the best apartment, They won't help you update your belief about the mean of a normal distribution, nor that it looks more like an Erlang distribution than a power distribution. Imagine walking into a casino full of different slot machines, each one with its own odds of a payoff. pleasure. The explore/exploit tradeoff tells us how to find the balance between trying new things and enjoying our favorites. the chickens—and, for. If you're lucky, it will tend to happen in the same place as well. Think long and I fully accept the evidence that in extreme cases, humans tend to exploit insufficiently. Explore - Exploit Problem. For this to work, you have to actually explore simpler options first, which one might not lean towards instinctively. So we can apply the rule for the normal distribution: if the logarithm of your observation is significantly less than the logarithm of the distribution's median (so let's say the observation is about half the median) just go with the median. But I still think that allowing long lists in my life is a problem. all human knowledge is uncertain, inexact, partial. Humans are pretty bad at reasoning with probability, few constraints are really fixed in stone, and we often have more options than can be considered. In the book Algorithms To Live By, Christian and Griffiths show how much we can learn from Computer Algorithms.The book goes over many algorithms like Optimal Stopping, Explore/Exploit, Caching, Scheduling, Predicting, Networking etc. If you have to search through something unsorted, you might have to go through every item. As you think about which path to take, you learn more about what is likely on each branch. further ahead they need. The chapter provides some evidence that humans tend to over-explore. Should we be worried about the lack of concrete advice? Sticking with simplicity is frequently our best option. Algorithms to Live By: The Computer Science of Human Decisions by Brian Christian and Tom Griffiths There are predictably a number of readers who will look at this title and shy away, thinking that a book with "algorithms" in its title must be just for techies and computer scientists. At first it seems like learning a new skill would be another example: you can learn different subskills or use different instructors. If this book offered large undiscovered gains in this area, I'd be pretty uneasy. The Gittins, index and the Upper Confidence Bound, as we’ve seen, inflate another idea from, computer science: “interrupt coalescing.” If you have five When n is 1, the Erlang distribution collapses to the exponential. decision-making (or of thinking more generally) are as If we imagine that everything is falling into the equilibrium in this scenario and everyone has the same payoff matrix, we can just imagine this as everyone takes holiday or not in unison. To see this, remember that the logarithm of a lognormally distributed variable is distributed normally (hence the name). Sorting theory tells us how (and We say, “brain fart” when we should really say “cache miss.” The If your pile of papers is well-sorted, you can do a binary search on it and find stuff quickly. Algorithms to Live By is a surprisingly fun book considering the subject. metrics might be just, as important. Humans really do need to sort and search stuff, and computer science algorithms apply in a straightforward way. Because new is unknown, and may be disappointing… Better go for something safe and sure (i.e., exploit). But in practice, when the clock—or the ticker—is But in a world where status is established If it had been new to me, it would have been quite valuable (though probably still not enough to move this section up). frustrating as we grow older, (like remembering names!) That said, if you need to sort a lot of material that you can only compare directly (rather than say, scoring) look to a merge sort. This is not merely an intuitively satisfying compromise If you have high Including hiring, dating, real estate, sorting, and even doing laundry. To provide my perspective on this, I wanted to share my own career journey and how I specifically leveraged an explore & exploit algorithm at every turn of my career to ultimately find my dream job. I did get one particular, communicable, useful idea from this chapter: interrupting someone more than a few times an hour can eat almost all the available work time in that hour. The fields of algorithmic relaxation & randomness explore answers to the above questions. But as you gain more knowledge, you lose some opportunities: branches get left behind as you follow the track of waiting and thinking. Imagine you and a friend are big film buffs, and want to go to the cinema together. But, the cultural practice of measuring status with quantifiable what would you do if you could not fail? Contains mathematical philosophy on decision making on a wide range of topics. “Algorithms to Live By”, a book written by Brian Christian and Tom Griffiths, looks at popular algorithms and applies them to solve our “human” problems. I found especially useful the (in retrospect, obvious) point that exploring is more worthwhile the longer you have to enjoy a payoff. [...]. While it sames safe to assume this is true for me as well, I think I have identified cases where I underexplore. At the top are several key quotes from the book, two of my favorites are "Inaction is just as irrevocable as… But as soon as everyone is, it pays to defect! It makes the model harder to work with, and improvements to its output are dubious at best. I will also consider placing items so that they're close to where they're needed. The claim is that, to oversimplify, you should always keep the things you just used closest to you, ignoring any other sorting by classification. This scenario is the “multi-armed bandit problem.” But they're not really behaviour changes and I haven't made any use of them yet. Similarly, when it comes time for you and your friend to pick a film, vetoing your least favourites could make it easier to zone in on an acceptable choice. So if car lifetimes are normally distributed for a given model, and your friend is driving a car that's slightly older than average for that model, expect that only has a few more years left in it. You can either play a strategy of taking holiday or not. Or one with a high expected value? If you'd like more detail on that, see the game theoretic note at the end. disproportionate, occasional lags in information retrieval are a reminder of Game theory is worth knowing about. How, asks the optimal stopping problem, can we maximise our probability of picking our most-preferred option? Anyway, it turns out that you should expect a constant amount of time to pass before the next event, no matter when you observe it. latencies, take heart: the length of a delay is partly an indicator of the extent Algorithms to Live By by Brian Christian & Tom Griffiths is an exploration of the applicability of algorithms from computer science to human decision problems. we are, “always connected.” But the problem isn’t that we’re always In a few paragraphs there's a reader's guide so you can skip around. If you are in a competition with others, the absolute quality might be quite unimportant. television. Explore vs exploit just how much we. So, as the book says, if you think the amount of money Hollywood films makes is distributed like total_money⁻¹, and you hear a film has made $1000 so far, your mean guess for its total should be $2000. Gwern has produced some practical prior art. I've failed to learn many skills because of all the time I spent picking between learning resources and subskills when I should have just been practicing. If you haven't, first think of the exponential distribution. equilibria, and information cascades. In a power law distribution, there's a fair amount of probability mass far out in the tail of the distribution. Algorithms to Live By takes you on a journey of eleven ideas from computer science, that we, knowingly or not, use in our lives every day. I'll copy two items from the book here: A possible way of using this is looking for your habit triggers in your life. effects of aging on, cognition. ticking, few aspects of. Personally, I think I am prone to complacency in such scenarios. Well, if b + h > s, or if b - k > 0 then not taking holiday no longer dominates. At each In English, the words “explore” and “exploit” come loaded with completely opposite connotations. It seems like we could have uncovered an avenue for novel, valuable advice. important as this one: over time. The baseline is taking no holiday in a low holiday environment. OK, so many of the problems humans face aren't deterministically solvable in a reasonable amount of time. On the other hand, there were definitely some problems. Because values across such a range of scales are possible, you should multiply your observed result by some constant. home; you’re just, calibrating. race rather than a, fight is a key part of what sets us apart from the monkeys, A naïve machine-learning algorithm doesn't have a prior against complex models. For example, the book opens with a discussion of so-called 'optimal stopping' problems. This makes sense, because it's the sum of variables that happen independently and memorylessly. However, I think that classifying things by reasonable categories must be helpful if I have trouble remembering where I put things. You miss an episode of, your favorite series and watch it an hour, a day, a decade But to a computer scientist, these words have much more specific and neutral meanings. The explore/exploit tradeoff tells us how to find the balance between trying new things and enjoying our favorites. have all the facts, they’re free of all error and uncertainty, and you can It has big economic benefits for individuals and organisations. Christian & Griffiths suggest reasons that people's tendency to favour exploration might be rational. Search costs (covered later) for valuable reading are definitely getting high. Apart from below the lognormal's median, they look kind of similar (but I prefer the lognormal cos of its reasonable behaviour around 0). the simplest. the game. I am more sceptical that this generalises. Nonetheless, I found it a useful lens to think with. I enjoyed this book a lot, so this review is going to be a long one. Algorithms to Live By. What an explorer trades off for knowledge is This is payoff h. As discussed, not taking holiday dominates taking holiday if s > h. This leads to a bad equilibrium: one where no one takes any holiday. When we study complexity, we study behaviour as the number of items they're processing gets large. Seek out games where Or try a new restaurant? I hadn't thought of this as a way to generate simplicity before. each—yet many of, those cars were on the road next to you, whereas the planes Compared to this, if you take no holiday in a high holiday environment, you get a payoff s, which represents increased likelihood of raises, promotions and so on. work between nations. There's one rule of thumb for three different distributions: power law distribution, Erlang distribution and normal distribution. “Some things that might seem literally. You can pass forever on an option or accept it and see no more options. What about if we ask for an OK solution? The authors write, LRU [...] is the overwhelming favorite of computer scientists. discrete states, model-based algorithms which perform exploration in a provably sample-efficient manner have existed for over a decade [24, 5, 47]. One awesome thing from this chapter were rules of thumb for certain estimates.
