Logo Primal training Support Vector Machines 1.0

by chap - November 19, 2007, 17:41:14 CET [ Project Homepage BibTeX Download ] 5161 views, 1129 downloads, 0 comments, 0 subscriptions

About: Very simple code for training SVMs in the primal. Works particularly well on sparse linear problems. In the non-linear case the entire kernel matrix needs to be computed, so for large problems it is [...]

About: In this paper, we propose an improved principal component analysis based on maximum entropy (MaxEnt) preservation, called MaxEnt-PCA, which is derived from a Parzen window estimation of Renyi’s quadratic entropy. Instead of minimizing the reconstruction error either based on L2-norm or L1-norm, the MaxEnt-PCA attempts to preserve as much as possible the uncertainty information of the data measured by entropy. The optimal solution of MaxEnt-PCA consists of the eigenvectors of a Laplacian probability matrix corresponding to the MaxEnt distribution. MaxEnt-PCA (1) is rotation invariant, (2) is free from any distribution assumption, and (3) is robust to outliers. Extensive experiments on real-world datasets demonstrate the effectiveness of the proposed linear method as compared to other related robust PCA methods.

Changelog pyGPs v1.3.1

November 25th 2014

structural updates:

  • full inline documentation with input parameter and output specified

  • check for the inputs and provide diagnostic messages for some inputs

  • consistant naming in inline and online documentation

  • string representation for dnlZStruct and postStruct. Now you can do sth like:

nlZ, dnlZ, post = model.getPosterior(x,y)

print post

  • instead of a python object, we provide now a more informative description.

  • add optimization into unit test routines. Also add checking for cholesky decomposition and checking positive-definite property of kernel matrix.

  • add jitter to the digonal of linear, linARD, and poly covariance for numerical stability.

  • fix several minor problems in unit test framework

  • hierachically rearranged for online documentation

  • add several supplementary instruction in online documentation
