Roger Labbe 3f798c6717 Pretty graphs are pretty.
Added a fill for the covariance to many of the charts.

I also fixed a code typo in the ensemble chapter.

Roger Labbe 203616ff1c Bug fixes and added example.
Several of the equations were slightly wrong. I made variables
bold when required, and added an example. I also expanded some of the
explanations.

Roger Labbe e76698dd33 Link to nbconverter and PDF at top of README.
This is mostly so that I the github.io page, which uses the README, has a ready
link to the PDF.

Roger Labbe 1fb0859e2c Rearrange, clean up, added implementation.
Rearranged the text and added implementation of the UKF. Not sure it
reads completely smoothly, but shoudl be better than before.

Still early going. just an experiement at this point.

Got a UKF working, just want to check point it.

Roger Labbe bf14f2fbc4 PEP-8 compliance. 2014-11-28 11:14:47 -08:00
Roger Labbe f9af363792 Bug in dog animation cell.
We were adding the movement error in the wrong place, causing the
filter output to never vary dispite changes in sensor noise.

Also some PEP-8 cleanup.
2014-11-28 10:33:10 -08:00
Roger Labbe 22375983c2 Fixed erroroneous statement about PDFs.
For some reason I stated the PDF displayed the probability,
not the probability density.

Roger Labbe c05c04a94e Better introduction.
Added Dan Simon's example of a range/bearing with noise to illustrate
nonlinear behavior.
2014-11-24 17:57:24 -08:00
Roger Labbe 3e5248f7fa More P,Q,R cleanup.
Added units to all values, corrected some descriptions, chose values to better
illustrate my points by causing either better or worse filter convergence.
2014-11-20 08:22:20 -08:00
Roger Labbe 66f20b745e More work on R and Q.
Added more examples and cleaned up explanations on modifying R
and Q. In particular, the filter setting for R was not the same
as the simulated noise for no obvious reason. Also, names were
bad R instead of R_var, for example.

Roger Labbe 60e31b890d Add references to smoothing chapter. 2014-11-16 16:12:14 -08:00
Roger Labbe 75c4e9ce97 Start of the Smoothin chapter. RTS implemented. 2014-11-16 15:54:28 -08:00
Roger Labbe 3367806b07 Layout changes to make PDF read better.
Mostly just shortening lines of code. There was a SymPy font render issue as well.
2014-11-16 11:24:59 -08:00
Roger Labbe c1281bc47c Cleanup of Q material, and rename of FilterPy.
I renamed the functions that compute Q in FilterPy and had
not propogated that through the book.

I have renamed FilterPy from filterpy, and propogated that
change through the book.

Moved the material on SymPy from the short lived Appendix C
to Appendix A

Roger Labbe 9c0729d837 Text on Approximating Q
Discussed approximating Q by only assigning a value to the
lower rightmost term.
2014-11-16 01:01:42 -08:00
Roger Labbe d974f78d37 EKF and Q content additions.
A lot of new text on designing Extended Kalman filters and
also on designing the Q matrix.
2014-11-16 00:42:47 -08:00
Roger Labbe e131cbb1c0 Reverted silly rename of .x to .X
x is a vector, not a matrix, hence it should be lower case like
it always was. I don't know what I was thinking when I renamed it.
2014-11-15 10:17:49 -08:00
Roger Labbe fd4b2211a7 Made sensor fusion code a function.
The function takes the wheel and gps variance in as parameters
so I can easily vary the values and display them to the reader.
2014-11-13 07:20:43 -08:00
Roger Labbe 9aa73ac8fe Added section on sensor fusion. 2014-11-12 20:54:44 -08:00

Roger Labbe 6e64160a2c Link fix, and filterpy information.
Fixed link to chapter 6, and added a section describing the filterpy library.
