I 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…Continue

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…Continue

(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…

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…Continue

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.Continue

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…Continue

In 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…Continue

We are all familiar with the dictum that "correlation does not imply causation". Furthermore, given a data file with samples of two variables…

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…Continue

The online conference, IBM Think 2020, was held in May 5-6 2020. During that conference, Dario Gil, IBM Research Director, was visibly, almost orgasmically, excited with his new toy, an IBM quantum computer.
The IBM quantum computer already gives a clear quantum advantage to all IBM partners, as long as they rent the version that is mounted on…Continue

About 4 months ago, I wrote for this blog an article entitled "List of Quantum Clouds". In that article, I listed 17 "quantum clouds". By now, there are probably a few more. The "HWB" (hardware backed) quantum clouds of Dwave, Rigetti and IBM, offer access to already existing, on-line qc hardware. I'll call all the other quantum clouds "proxy" quantum…Continue

Check out the following paper unveiled last night in ArXiv:
An Open-Source, Industrial-Strength Optimizing Compiler for Quantum Programs, by Robert S. Smith, Eric C. Peterson, Mark G. Skilbeck, Erik J. Davis.
This is an exciting development for me since I have been a proponent and practitioner of the art of quantum compilers for a long time.
The new "optimized quantum compiler" by Rigetti is a computer program that tackles the problem of…Continue

Today, Google published the following paper:
TensorFlow Quantum: A Software Framework for Quantum Machine Learning,
TensorFlow Quantum is software for doing Quantum Bayesian Networks. QB nets have been a dream of mine for 24 years, although Google's paper, despite having 20 authors and 129 references, never cites any of my work. When I first had the idea of Quantum Bayesian Networks, I thought it was such a cool idea that, within a span of a year, I published…Continue

Quantum computers come in 2 varieties, quantum annealers and quantum gate models. So far, DWave is the only company selling quantum annealers.
A third type of device is now available from Fujitsu. Fujitsu calls its device a "quantum inspired digital annealer". The Fujitsu device does not have any quantum correlation (quantum entanglement)…Continue

Clouds for doing quantum computing are becoming increasingly popular. Here is a list with links of those quantum clouds that already exist or are imminent. All are commercial but usually free for small jobs and open to the public. Most use open source q c software but some don't and have opted to keep their software proprietary. In Alphabetical Order. ✅…Continue
