Causal Reinforcement Learning under Bareinboim at Columbia Univ.

Elias BareinboimI recently wrote a popular article on Causal AI. Note that Causal AI is almost exclusively the province of Bayesian networks (bnets), not of their more puny brethren, neural networks (NNs). Indeed, Causal AI is based on Judea Pearl's theory of causality which is expressed via bnets, not NNs.Something that I didn't mention in my popular article because I didn't know it at…See More

Quantum Neural Net, an Oxymoron

Venn diagram showing overlap between "quantum" and "neural network"The term "quantum neural networks" is being used with increasing frequency by the quantum computing community. Maybe as a dishonest, bait-and-switch advertising strategy, this makes sense. However, from a scientific standpoint, "quantum neural network" is a very poor name choice for what is being alluded to here.Artificial Neural Networks, often called "Neural Nets" for short, are supposed to mimic the actual neurons in the…See More

Simpson’s Paradox, the Bane of Clinical Trials

(This article is now a chapter of my github proto-book Bayesuvius) Simpson's paradox is a recurring nightmare for all statisticians overseeing a clinical trial for a medicine. It is possible that if they leave out a certain "confounding" variable from a study, the study's conclusion on whether a medicine is effective or not, might be, without measuring that confounding variable, the opposite of what it would have been had that variable been measured. Statisticians have to enlist expert…See More

Added Chapter on Reinforcement Learning to my book “Bayesuvius” on Bayesian Networks

I just uploaded a new chapter to my github proto-book "Bayesuvius". This chapter deals with Reinforcement Learning (RL) done right, i.e., with Bayesian Networks :)My chapter is heavily based on the excellent course notes for CS 285 taught at UC Berkeley by Prof. Sergey Levine. All I did was to translate some of those lectures into B net lingo.During a recent conversation that I had on LinkedIn with some very smart Machine Learning experts, the experts opined that the fields of RL and B nets did…See More

Today I uploaded to github the first version of my book "Bayesuvius" about Bayesian Networks

View of Mount Vesuvius form PompeiiIn the last week, I started a new book on classical (not quantum) Bayesian Networks. Today, I uploaded the first installment to github. Here is its github repo. Here is the pdf for the book. Let me quote the current Foreword.Welcome to Bayesuvius! a…See More

QC Paulinesia, !(yet another book about quantum computing)

Today I uploaded to github the first version of my book “QC Paulinesia” about Quantum Computing. The title is a play on the surname of the famous quantum scientist Wolfgang Pauli and the word "Polynesia". The book is based on a paper with the same name that I wrote in 2004. Here is  its github repo. Here is the pdf for the book. Let me quote the current Foreword.…See More

Generative Adversarial Networks (GANs) & Bayesian Networks

Generative Adversarial Networks (GANs) software is software for producing forgeries and imitations of data (aka synthetic data, fake data). Human beings have been making fakes, with good or evil intent, of almost everything they possibly can, since the beginning of the human race. Thus, perhaps not too surprisingly, GAN software has been widely used since it was first proposed in this amazingly recent 2014 paper. To gauge how widely GAN software has been used so far, see, for example, this 2019…See More

Causal AI & Bayesian Networks

Bullet ripping through Jack of Hearts. High speed photo by MIT's Harold (Doc) Edgerton. Artist Harry Clarke's 1919 illustration for "A Descent into the Maelström" Introduction We are all familiar with the dictum that "correlation does not imply causation". Furthermore, given a data file with samples of two variables x and z, we all know how to calculate the correlation between x and z. But it's only an elite minority, the few, the proud, the Bayesian Network aficionados, that know how to…See More

"Thanks for sharing your experience with us. It was very enlightening. However, I think Python is quite simple. Any Data Scientist that can't learn it in a day or two is not worth his $150K/yr salary. The beauty of Python is not only its…"

Information Theory (Turbo Codes) & Bayesian Networks

An error correcting code (ECC) is a way of controlling errors in data that is being transmitted over an unreliable or noisy communication channel. In an ECC, the sender encodes the message with redundant information. The receiver is able to detect a limited number of errors, and to correct these errors without retransmission.Turbo codes are a class of ECC that approach very closely the theoretical optimum for…See More
