## Free E-Book: Neural Networks and Deep Learning by Michael Nielsen

Bookmarked Neural networks and deep learning (neuralnetworksanddeeplearning.com)
Michael A. Nielsen, the author of one of our favorite books on Quantum Computation and Quantum Information, is writing a new book entitled Neural Networks and Deep Learning. He’s been releasing portions of it for free on the internet in draft form every two or three months since 2013. He’s also maintaining an open code repository for the book on GitHub.

## Introduction to Lie Groups and Lie Algebras (Part 2) | UCLA Extension

Dr. Mike Miller, who had previously announced a two quarter sequence of classes on Lie Groups at UCLA, has just opened up registration for the second course in the series. His courses are always clear, entertaining, and invigorating, and I highly recommend them to anyone who is interested in math, science, or engineering.

Prior to the first part of the course, I’d written some thoughts about the timbre and tempo of his lecture style and philosophy and commend those interested to take a peek. I also mentioned some additional resources for the course there as well.  For those who missed the first portion, I’m happy to help fill you in and share some of my notes if necessary. The recommended minimum prerequisites for this class are linear algebra and some calculus.

### Course Description

A Lie group is a differentiable manifold that is also a group for which the product and inverse maps are differentiable. A Lie algebra is a vector space endowed with a binary operation that is bilinear, alternating, and satisfies the so-called Jacobi identity. This course is the second in a 2-quarter sequence that offers an introductory survey of Lie groups, their associated Lie algebras, and their representations. Its focus is split between continuing last quarter’s study of matrix Lie groups and their representations and reconciling this theory with that for the more general manifold setting. Topics to be discussed include the Weyl group, complete reducibility, semisimple Lie algebras, root systems, and Cartan subalgebras. This is an advanced course, requiring a solid understanding of linear algebra, basic analysis, and, ideally, the material from the previous quarter.Internet access required to retrieve course materials.

## BIRS Workshop on Biological and Bio-Inspired Information Theory | Storify Stream

Over the span of the coming week, I’ll be updating (and archiving) the stream of information coming out of the BIRS Workshop on Biological and Bio-Inspired Information Theory.

Editor’s note: On 12/12/17 Storify announced they would be shutting down. As a result, I’m changing the embedded version of the original data served by Storify for an HTML copy which can be found below:

81. A few thoughts about that workshop while I wait for my flight back to Toronto.
82. 1/ Everyone I talked to said it was the best workshop they’d ever been to, and they’d like to do a follow-up workshop @BIRS_Math
83. 2/ There is an amazing diversity of work under the umbrella of “information theory”. @BIRS_Math
84. 3/ Much of this work is outside the IT mainstream, and an issue is that people use different terms for related concepts. @BIRS_Math
85. 4/ Some community building is in order. I think this workshop was a good first step. @BIRS_Math
86. 5/ Many many thanks to @BIRS_Math and huge kudos to @NGhoussoub for excellent service to the Canadian scientific community. BIRS is a gem.
87. 6/ Also many thanks to the participants for their excellent talks, and to @ChrisAldrich for maintaining a Storify.
