From Wikipedia: Bayesian interpretation expresses how a subjective degree of belief should rationally change to account for evidence XKCD: Frequentist vs. Bayesian Statistics. Two approaches to problems in the world of statistics and machine learning are that of frequentist and Bayesian statistics. This comic from XKCD illustrates a difference between the two viewpoints. We have a neutrino detector that measures whether the sun has gone nova

xkcd: Modified Bayes' Theore

After an episode about significance, xkcd has now reached the intellectual stage of joking about correlation and causation and how they might — or might not — relate to each other.. So the question is: when is he [= MAP gender of comic creator] going to mention Bayes in some way? It's only a matter of time, surely, and I'll take that as a sign that it's as mainstream (in geek circles. 303 votes, 33 comments. 140k members in the xkcd community. /r/xkcd is the subreddit for the popular webcomic xkcd by Randall Munroe. Come to Bayes' Theorem: XKCD at the beach This is roughly equal to # of times I've picked up a seashell at the ocean # of times I've picked up a seashell;...which in my case is pretty close to 1, and gets much closer if we're considering only times I didn't put it to my ear. 1 Modified Bayes' Theorem. (alt-text) Don't forget to add another term for probability that the Modified Bayes' Theorem is correct. |< XKCD today is about p values (see image at right). I think that what XKCD is pointing out is not so much a problem with p values as with strongly institutionalized publication thresholds and the ritual of mindless statistics, as Gigerenzer would say.The same problem could arise with strongly institutionalized publication thresholds for Bayes factors, or even for HDI-and-ROPEs

XKCD's modified Bayes theorem: actually kinda reasonable? Get lin The frequentist knows (because he has written reports on it) that the Bayesian sometimes makes bets that, in the worst case, when his personal opinion is wrong, could turn out badly. I feel like every time the topic comes up, 'Bayesian statistics' is an applause light for me, and I'm not sure why I'm supposed to be applauding. The frequentist also knows (for the same reason) that if he bets. XKCD comic on Frequentist vs Bayesian. Those differences may seem subtle at first, but they give a start to two schools of statistics. Frequentist and Bayesian approaches differ not only in mathematical treatment but in philosophical views on fundamental concepts in stats

1132: Frequentists vs

  1. In today's XKCD, a pair of (presumably) physicists are told by their neutrino detector that the sun has gone nova.Problem is, the machine rolls two dice and if they both come up six it lies, otherwise it tells the truth. The Frequentist reasons that the probability of obtaining this result if the sun had not, infact, gone nova is 1/36 (0.027, p<0.05) and concludes that the sun is exploding
  2. I came across this post http://xkcd.com/1132/ and this image I didn't get why the Bayesian statistician is saying no. Any suggestio
  3. Maybe xkcd's tagline does provide a strong prior belief of a small number of topics, but here we take a more objective approach and let the data choose the number of topics. An optimal number of topics is found using the Bayesian model selection approach (with uniform prior belief on the number of topics) suggested by Griffiths and Steyvers ( 2004 )

  1. Ooooookay. So, very long story short... They're two different academic traditions for what constitutes Good Statistics. They're originally rooted in the philosophical dispute over whether to treat probabilities as frequencies of random outcomes (frequentist) or as degrees of plausibility (Bayesian).. In actual fact, a well-trained frequentist knows exactly how and when to use Bayes' rule.

  3. Bayes' rule is a powerful tool for calculating the P you want to know. It includes a mechanism for weighting the strength of evidence in the likelihood part of a formula. When calculating P(theory | data) and having been given P(data | theory) - the likelihood of the data given the theory - we know that we must learn or estimate the prior P(theory) to do the Bayesian flip

  5. Frequentist vs Bayesian Statistics, Image: XKCD Conclusion In conclusion, we can say that Bayesian Statistics are a method that appoints degree of belief, or Bayesian probabilities, to customary factual demonstrating
  6. Source: xkcd.com Naive Bayes Classifier. As the name suggests the Naive Bayes classifier uses the Bayes rule with naive assumptions.We will see what that means after we define some jargon
  7. Since a deck of 52 playing cards contains 4 aces, the probability of drawing the first ace is 4/52. But the probability of drawing an ace given the first card drawn was an ace is 3/51 — 3 aces left in the deck with 51 total cards remaining. Hence, conditional probability assumes another event has already taken place. False Positives and False Negatives: What They're No

How to frame this statistically? • Maximum Likelihood Approach • Idea: rewrite the ODE model as a statistical model, where we suppose we know the general form of the density function but not the parameter values • Then if we knew the parameters we could calculate probability of a particular observation/data When comparing hypotheses with Bayesian methods, the similar 'clickbayes factor' can account for some harder-to-quantify priors. |< <? > > I am happy to see statistical theory and methods be a topic in popular culture, and of course I'm glad that, contra Feller, the Bayesian is presented as the hero this time, but . . . .I think the lower-left panel of the cartoon unfairly misrepresents frequentist statisticians Drexel University coursework.

The Bayesian approach would naturally detect that the color-based model in the XKCD jellybean experiment above had a lower Bayes factor than the simpler model, regardless of how many colors are tested and without any artificial or external correction factors The Bayes factor is problematic because it is used to answer a question—What is the probability that model 1 or model 2 is true—that is typically meaningless. I have a lot less problem with numbers that are more direct answers to scientific or engineering questions, for example predictions or estimated averages or differences or parameters in a model

By contrast, the values of other parameters (typically node weights) are derived via training. Hyperparameters can be classified as model hyperparameters, that cannot be inferred while fitting the machine to the training set because they refer to the model selection task, or algorithm.
