7c9eda482c Moved transf_data to make data -1 or 1 from 0 or 1 for bernoulli 
with probit into the analytical moment match (but it 10% slower),
needs removing from epmixednoise

5f9d7eb709 Changed naming from old derivatives of likelihoods to new ones 
in noise distributions

10f3f7d14a Refactored gradients wrt parameters slightly, need to future proof against _get_param_names() disappearing 2013-10-17 18:33:08 +01:00
Alan Saul
1848653fce Added more options to generic tests (constraining link function 
values as bernoulli requies R^{0,1}) and implemented new gradients
for bernoulli

f3fd9f1325 Rename Binomial to Bernoulli (maybe generalise it with the constant 
later, but tilted distribution may change)

afd38df1ef Added pdf_link's for gaussian and student t, added third derivatives for 
transformations and tests for them

dc12fb43b7 Added configuration file 
this was done to solve the OpenMP problem on Windows/mac, but I think it
is useful in general. All unit tests pass except the sympy kern ones.

0344324571 Still tidying up, laplace now working again, gaussian and student_t 
likelihoods now done

fe30db1331 Updated sympy code, multioutput grad checks pass apart from wrt X. Similar problems with prediction as to sinc covariance, needs investigation. 2013-10-14 09:37:35 +01:00

a92780cb89 Added olivetti faces data set. It required adding netpbmfile.py a bsd licensed pgm file reader from Christoph Gohlke, which doesn't seem to have a spearate installer. Also modified image_show to assume by default that array ordering is python instead of fortran. Modified brendan_faces demo to explicilty force fortran ordering. Notified Teo of change. 2013-10-14 05:59:15 +01:00

6945ad7aa1 Seems to work on windows now 
not everything works yet, but I've identified the main issues. Still
TODO: handle missing OMP libraries gracefully
