I do not rely much on my cell phone. It functions as a tool for confronting emergencies. On the other hand, it seems like people do lots of things with their smart phones and I like to add one thing to your “what I do with my phone.” Continue reading ‘Wapedia’ »

My greatest concern was what to call it. I thought of calling it “information”, but the word was overly used, so I decided to call it “uncertainty”. When I discussed it with John von Neumann, he had a better idea. Von Neumann told me, “You should call it entropy, for two reasons. In the first place your uncertainty function has been used in statistical mechanics under that name, so it already has a name. In the second place, and more important, nobody knows what entropy really is, so in a debate you will always have the advantage.”

I didn’t realize this post was sitting for a month during which I almost neglected the slog. As if great books about probability and information theory for statisticians and engineers exist, I believe there are great statistical physics books for physicists. On the other hand, relatively less exist that introduce one subject to the other kind audience. In this regard, I thought the lecture note can be useful.

I found this website a while ago but haven’t checked until now. They are quite useful by its contents (even pages of the lecture notes are properly flipped for you while the lecture is given). Increasing popularity of machine learning among astronomers will find more use of such lectures. If you have time to learn machine learning and other related subjects, please visit http://videolectures.net/. Specifically classified links to interesting subjects are found by your click.

Frankly, there was no astrostatistically interesting paper from astro-ph this week but profitable papers from the statistics side were posted. For the list, click Continue reading ‘[ArXiv] 2nd week, Oct. 2007’ »
