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.

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

not everything works yet, but I've identified the main issues. Still
TODO: handle missing OMP libraries gracefully
