Usefulness of Computer Science: An Example

I thought I would follow up on my June 29 post, “Does Computer Science Help with OR?“, by giving a quick example of how exposure to fundamentals of computer science recently helped me. A current research project involves optimization models containing large numbers of what are basically set covering constraints, constraints of the form \(\displaystyle …

Does Computer Science Help with OR?

Fair warning: tl/dr. After reading a blog post yesterday by John D. Cook, “Does computer science help you program?“, I decided to throw in my two cents (convert to euros at your own risk) on a related topic: does computer science (which I will extend to including programming) help you as an OR/IE/management science/analytics professional? …

Epistemic Caution and Climate Change

I have not, until recently, invested significant time in trying to understand climate modeling. These notes are primarily for my own use, however I welcome comments from readers who have studied this issue in more depth. I take a dim view of people who express strong opinions about complex phenomena without having understood the underlying …

History of Bayesian Neural Networks

This talk gives the history of neural networks in the framework of Bayesian inference. Deep learning is (so far) quite empirical in nature: things work, but we lack a good theoretical framework for understanding why or even how. The Bayesian approach offers some progress in these directions, and also toward quantifying prediction uncertainty. I was …

Neural Networks and Deep Learning 2

Inspired by the topics discussed in this earlier post, I’ve been reading Michael Nielsen’s online book on neural nets and deep learning. I particularly liked the subsection quoted below. For people who think deep learning is anything close to a solved problem, or anticipate a near term, quick take-off to the Singularity, I suggest they …

Neural Networks and Deep Learning

One of the SCI FOO sessions I enjoyed the most this year was a discussion of deep learning by AI researcher Juergen Schmidhuber. For an overview of recent progress, see this recent paper. Also of interest: Michael Nielsen’s pedagogical book project. An application which especially caught my attention is described by Schmidhuber here: Many traditional methods …
