Roger Labbe 6933c33dbc Copy editing. 2016-01-13 17:33:14 -08:00
Roger Labbe 5921b20f87 Word smithing. 
Just trimming the flab.
 2016-01-12 20:57:13 -08:00
Roger Labbe ffaee9b080 Removing flab from language. 2016-01-10 20:46:43 -08:00
Roger Labbe fb7db6d752 More removal of flabby language. 2016-01-10 10:14:29 -08:00
Roger Labbe 974543a603 Fixed code bug due to renaming function. 
I renamed the function f, but did not propogate that change
to every cell.

Roger Labbe d9ba9fde22 Scatter plot of bearing shows 2 results. 
The text in the book gave one example, and then hand waved an
explanation about a different bearing choice. It is clearer to
just show it in a graph.
 2016-01-10 09:00:00 -08:00
Roger Labbe 58d91c2de3 Copy and general edits. 
Trimming the flab out of the language. Added a few examples and
such to clarify concepts.
 2016-01-10 08:58:37 -08:00
Roger Labbe 8e2bb6856d Fixed error in latex 
It rendered fine in the notebook, but \text{foo_bar} was causing
an error in the pdf generation. Switching to \mathtt{foo\_bar}
mostly fixes it (though in the notebook it renders as -, not _.
Oye.
 2016-01-09 09:10:56 -08:00
Roger Labbe 800ea6c189 Cleaned up equations for UKF. 
I was using a bunch of variable names that weren't consistent
with the rest of the book (but perhaps are more consistent with
the literature). It just made everything more challenging than
it needed to be, so instead of \mu and \sigma (e.g.) I use
\bar x and \bar P.

I also am in the middle of rewriting some sections for clarity,
but that work is not completed.

Roger Labbe b6d5052f45 Copy edits. 2016-01-09 08:51:24 -08:00
Roger Labbe eeab89c16c Copy edits. 2016-01-09 08:51:03 -08:00
Roger Labbe 6b9b97927d Redid Discrete Bayes animations. 
I added titles so you can see where in the processing the
graph is.

This surfaced a bug in matplotlib 1.5 (#5399) so I added
some code to work around that.
 2016-01-09 08:49:29 -08:00
Roger Labbe 65a77d0af2 Commited before I saved the file! 2016-01-09 08:20:53 -08:00
Roger Labbe 8bab476b31 Edited so I can report bug to matplotlib. 2016-01-09 08:20:28 -08:00

Roger Labbe 331d8cf880 Minor copy editing. 2016-01-03 11:32:07 -08:00
Roger Labbe 462ac1bb5c Fixed obsolete import, hard code of filename 2016-01-03 10:43:45 -08:00
Roger Labbe 122fe27680 changed from \bar to \overbar for prediction. 
More visible, and works better with things like matrices.
 2016-01-02 18:10:15 -08:00
Roger Labbe ab33584a0c Minor copy edit and code clean up. 
Biggest change was changing the variable for noise to use
either std or var.
 2016-01-02 18:08:43 -08:00
Roger Labbe 09406a6419 Added explanation for system dynamics matrix. 2016-01-02 18:07:00 -08:00
Roger Labbe fee08bfc7b Moved iterative ILD to supporting notebooks 
Most people just won't want to read this material.
 2016-01-01 15:43:50 -08:00
Roger Labbe 47cce41efb Moved Taylor Series to supporting notebooks. 2016-01-01 15:28:55 -08:00
Roger Labbe b2a3ce2a28 Major rewrite of matrix exponential section. 
I was conflating thematrix exponential with Taylor series, making
the whole thing quite confusing.

There was also significant duplication of content, such as presenting
the calculus form of Newton's equations multiple times in slightly
different ways. I've made it all hang together now.
 2016-01-01 15:18:35 -08:00
Roger Labbe 2610c4dc85 Merge branch 'master' of https://github.com/rlabbe/Kalman-and-Bayesian-Filters-in-Python 2015-12-27 08:13:14 -08:00

code directory: Add __init__.py for access as package
 2015-12-27 08:12:52 -08:00
Roger Labbe 63c398fc51 changed \bar to \overline 2015-12-20 12:42:30 -08:00

Roger Labbe 5ffd42a25d Fixed FilterPy versioning check error. 
The code only worked for the third version number. If the first
or second version numbers were too small it didn't detect it.
 2015-12-20 10:08:31 -08:00
Roger Labbe 033dbea735 Copy edits. 2015-12-20 10:08:15 -08:00
Roger Labbe 108a3f1a4d Copy edits. 2015-12-20 09:00:26 -08:00
Roger Labbe 672e4bb3c5 Updated code listings. 
Note sure I like this appendix, but as long as it exists it should
be up to date.
 2015-12-20 08:59:58 -08:00
Roger Labbe 0e86469fac PDF build scripts build 6x9 book separately. 2015-12-20 08:59:11 -08:00
Roger Labbe 05caf4f1bb Copy edits. 2015-12-20 08:44:28 -08:00

It is just too complicated for this book.
 2015-12-20 08:34:42 -08:00
Roger Labbe dd1bb52baa Improved description of KFs. 2015-12-20 08:32:06 -08:00
Roger Labbe 0236af896d Added text for computation of velocities. 
I explained how the covariances are computed by FPF',
and then how the velocity is computed using the kalman gain.
 2015-12-19 21:12:41 -08:00
Roger Labbe 77ba700e39 Revised particle filter chapter. 
Pretty happy with it now. Needs copy editing, and probably an
easier introduction to convey the basic idea. Moved from a class
based approach to a procedural approach, and I like that very much.
 2015-12-19 16:18:21 -08:00
Roger Labbe 3c270d0c87 Fixed latex typo. 2015-12-19 16:17:40 -08:00

Minor wording changes to clarify meaning.
 2015-12-15 16:05:01 -08:00
Roger Labbe e12352c520 Fixed equation for total probability theorem. 
I was using the wrong subscript (i instead of j) in the sum.
 2015-12-15 15:45:26 -08:00
Roger Labbe 04ce859d01 Minor copy editing. 2015-12-13 15:16:33 -08:00

Roger Labbe a1a1753c18 Fixed description of fixed-point filter. 
I mistakenly stated that it re-estimated the points between times
j and k, when of course it recomputes only a single fixed point.
 2015-12-10 20:21:13 -08:00
Roger Labbe 9ece51233b Minor copy edits. 2015-12-10 19:31:41 -08:00

Roger Labbe c0fe5e7de8 Book format changes. 
Moved book_format out of code to simplify importing it into the
notebooks. Added code to it to suppress future warnings from
matplotlib 1.4.3, and to set the numpy print precision to 3
decimal places.
 2015-11-25 13:29:40 -08:00
Roger Labbe 7cd8e11b57 More work on multivariate gaussians. 
Not copy edited yet, but more work on making the material on
multivariate gaussian more understandable (mostly by reordering
concepts).

Roger Labbe 7c9bedca38 Fixed animations. 
Not sure why, but the two line title was being cut off when
displayed. I must have changed somethign in the matplotlib
sytle at some point that broke this.
 2015-11-25 12:01:32 -08:00
Roger Labbe 6f6108780c Fixed errorbar plots in gh chapter. 
I changed the ZZy-axis earlier, which meant that the bar for
sensor A was not visible.
 2015-11-25 12:00:38 -08:00
Roger Labbe fe79d7409f Improved correlation examples. 
Switched house floor plan vs price to student height and weight.
This matches with the Gaussians chapter that found the variance
in heights.
 2015-11-24 09:40:08 -08:00
Roger Labbe 3966f3d707 Removed try/except block

Roger Labbe f07250b8f0 Fixed language about 'next chapter'. 
I split the multivariate KF chapter into two, so references to the
'next' chapter were inaccurate.
 2015-11-22 11:58:43 -08:00
Roger Labbe 1b71b73c55 Reran cells 
Forgot to rerun all cells before last check in.
 2015-11-22 11:14:13 -08:00
Roger Labbe db4f275575 Rewrite and reorganization 
Worked on getting the 'flow' of information to be more logical.

Added a section on comparing a uniform, Gaussian, and discrete
distribution to model errors so the reader can better understand
the relationships between the three filters.
 2015-11-22 11:11:50 -08:00
Roger Labbe 791819d76f fixed latex typos. 2015-11-21 14:27:27 -08:00

Roger Labbe 56bea69ea6 Extensive improvements. 
Many worked to explain random variables much better than before,
and otherwise streamlined the explanations so they support the
rest of the book better. Moved some material from the math chapter
in support of this.

Roger Labbe b0f84e0c16 Merge pull request #70 from dnstanciu/master 
Fixed JSON settings being overwritten with matplotlib version.
 2015-11-20 16:16:09 -08:00
Roger Labbe 56ede47d83 Fixed deprecated use of axes.color_cycle 
Matplotlib 1.5 deprecrates the use of axes.color_cycle in favor
of axes.prop_cycle

I prefer to use the new styles coming from matplotlib, but for now,
to maintain backwards compatibility, I am hand coding the styles
still.
 2015-11-14 08:55:24 -08:00
