f942a8abfc Fixed text describing Gaussian prediction calculation, in particular changed to use sigma, instead of mu when describing the variance update. 2017-07-20 11:02:26 -04:00

cd7f3605ae Fixed estimates that were not tracking under 'Control Inputs'. Measurements were generated under assumption of dt=1, but were updating states from model using dt=0.1. 2017-07-20 03:01:56 -07:00

1c11186fa4 Bug in train_filter
Called normalize(belief), when it should have been normalize(prior).
belief is a variable from another cell, and not used in this function.

d15845bde8 I reversed the explanation of product/sum for Gaussians, saying the
sum is proportional and the product is Normal. Of course the reverse
is true.

529585a4c8 Issue #144 - update variable est/prediction names
I erroneously named the prediction of x x_est, which is confusing at best.

There were also issues with plotsize. The %matplotlib notebook magic
is resetting the size of the plots. Not sure if this has something to do
with some of my plotting code or not. Anyway, I wrote a context manager
to reset the plot size after exiting interactive mode.

Add 'Estimates' to legend

I added a comment header to the plotting routine, and renamed `retval` to `lines` (I prefer meaningful names whenever possible.

3d288d60d6 The base python installation has a file code.py; this causes
problems when trying to import files from the code subdirectory.

I also tried to rearange some code so that book_format does not need
to be imported if you are not running in a Jupyter Notebook.

c97186c8b4 Fixed PDF generation re %matplotlib magic
Fixed the scripts that comment out the matplotlib magic.
It was commenting out all of the magics - the first one, and
ones in markdown cells. It should only comment out the ones
in code cells, and leave the first one.

91e9e08377 Removed #reset from magic
I was using comment to detect which %matplotlib inline to comment
out to generate the PDF but it generates a UsageError. I need to make
my script smarter instead. The problem is that I don't want to remove
the first inline definition

6bafbd490e I switched the weight gain guess back to 1 (the corrct value - of
course the filter would find the right answer. Leaving at -1 shows
that the filter works well even when the initial estimate is incorrect.

and then create the PDF.
