6a24f45c68 Trying to get it to work with nbviewer 
Book was not showing up formatted. I think because I strip output on check in.

45164b96f4 Learning to format README.md. 
Just mostly editing to see changes at this point.

87e595078b Fixed code that explicitly calculated weight. It was buggy. 2014-05-15 23:58:27 -07:00

b995668db1 A lot of new g-h filter code and text added. 2014-05-15 15:55:05 -07:00

3b4c5a547c Added stuff for Q. 
I was erroneously using a scalar for Q. I made it into a matrix. However,
I am pretty sure it is still wrong. Q shouldn't be symmetric.

bae77c1d02 Format changes and multidimensional KF content. 
Modified the css style to use colors and fonts more to my liking. Still needs
tweaking.

Added a lot of content to the multidimensional KF chapter.

09fa08f73e mv'ed gaussian.py to stats.py 
The name was horrible, we were using gaussian.gaussian() to compute
gaussians. stats.gaussian() is much better. Updated all notebooks
and scripts to reflect the change.

6e5c02ad36 Contains functions useful to the Gaussian chapter. 
We do not want to expose all of the Python code used to generate the book
because it just makes things unreadable.

2f74f90c18 Added ability to label the axes. 2014-05-09 13:55:53 -07:00

3504351fe6 Moved description of histogram problems to this chapter. 
The kalman filter chapter lead off with a long discussion of the problems
with histograms. That seemed to belong more at the end of the histogram
chapter, so I moved it there.

412344fe72 More examples and exercises. 
Added a new KF that filters a temperature sensor. Discussed what to do if
there is no data for update().

bcc62c7984 Correct some minor English issues. 
Wrote a bunch of exercises and solutions for the Kalman filter.

ef22d7e62a Removed use of --pylab inline, as I mistakenly thought that was the best 
way to get matplot lib to be inline. Also, imported print_function from
future to try to be 3.X compliant.

3b9bb1fd44 More work on various parts of the multidimensional filter. 
Added custom CSS style for formatting the book.

b31e3a0b12 I think outputs are now correctly removed before check in. 2014-05-06 10:01:27 -05:00

71b1b12212 Another attempt to remove output - script did not point to ipython 2014-05-06 09:56:40 -05:00
Roger Labbe
9ae5aea761 Added hook to git to remove all notebook output prior to committing. 
This should make git ignore differences caused by merely running a notebook.

499f8d91f5 Various changes. Main thing is removed the slow gaussian class from 
the kalman filters. It was annoying anyway - have to pack and unpack
it everywhere when calling around.
 2014-05-04 17:33:39 -05:00

8305200ff0 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.

d3800c5a4f Added a lot of code to display covariance ellipses. 
Also some progress in writing about covariances in relation to
Kalman filtering.

0b149352ed Interim check in. 
dog_track_1d is just a file to test code before putting it into the
Kalman filter chapter.

fdae26c7b8 Beginning of the Kalman Filter 1D chapter. 
Just 1 hour in, not a notable check in. Just checkpointing it.

Partial authorship of introduction to the gaussian chapter.

5ac3bb5017 Expanded the introduction. 
I think I said most of what I wanted to say. I don't really explain what a
Kalman filter, but then who would really be reading the book if they don't
know. Still, a basic introduction to what they can do, and what Bayesian
filters are is probably a good idea.
