Lie Groups




Lie Groups, a Fantastic book by Daniel Bump

published by Springer Press 2013

This is a graduate math level text. Concise with lots of proofs. The chapters are short enough to read in one sitting. Chapter 7 goes over that a Lie group is a differential manifold.

I was asked to look for books on this topic. It was challenging to search for material with this title.  This was the best book that I could find.

I look forward to exploring this topic further.

8th International Workshop, WALCOM 2014, Chennai, India, February 13-15, 2014, ProceedingsPal, S.P. (et al.) (Eds.)
Publication year 2014 by Springer Press

Interesting collection of papers from WALCOM conference. I would like to have been there.  It is interesting to read about current research. Like Top-k Manhattan Spacial Skyline Queries.

A (k+1) Approximation Robust Flow Network Algorithm and a Tighter Heuristic Method using Iterative Multiroute Flow paper by Jean-Francois Buffier and Vorapong Suppakitpaisarn

There are many more insightful papers. I can’t wait to see what get developed next.

Graphical Models with R


Graphical models with R by Soren Hojsgaard, David Edwards and Steffen Lauritzen published by Springer

I have been to a lot of talks lately on graphing social networks. Most of the code has been in python. I was happy to find this book written in R.
gRbase is the package for the book.
Most of the packages used in the book are on cran. The missing few dependencies are on Links to the site are on the gRbase part of cran. With some fiddling I got everything to work correctly.

Chapter 2.3.5 covers Hypothesis testing with graphical models.

I have been busy working thru all the examples in the book. Making lots of big spidery graphs that make sense. I am pleased with the mix a theory and code in this book.

I am thinking about what data to use with the code for an upcoming talk that I am giving.
