A lot of changes. I think a lot of changes to the notebooks are just due to running them. In the process of adding a bunch of new .py scripts to support the book. Most important is the DiscreteBayes1D.py class, which implements a Discrete Bayesian filter in a generalized way. 2014-05-03 04:49:35 +02:00			`# -- coding: utf-8 --`

Added animations to Discrete Bayes Beginning of adding animations to the chapters. I wrote the existing material not assuming animations, so it is quite possible that I will want to revise the chapter to better make use of this ability. For now I just animated two different update/predict cycles. 2014-09-13 20:15:40 +02:00			`def plot(pos, ylim=(0,1), title=None):`
