Logo Information Theoretical Estimators 0.37

by szzoli - May 12, 2013, 15:35:39 CET [ Project Homepage BibTeX BibTeX for corresponding Paper Download ] 10358 views, 2099 downloads, 1 subscription

About: ITE (Information Theoretical Estimators) is capable of estimating many different variants of entropy, mutual information, divergence, association measures and cross quantities. Thanks to its highly modular design, ITE supports additionally (i) the combinations of the estimation techniques, (ii) the easy construction and embedding of novel information theoretical estimators, and (iii) their immediate application in information theoretical optimization problems.

Changes:
  • K divergence estimation: added,

  • L divergence estimation: added,

  • kNN squared distance computation: refined.

About: The GPML toolbox is a flexible and generic Octave 3.2.x and Matlab 7.x implementation of inference and prediction in Gaussian Process (GP) models.

Changes:

We now support inference on large datasets using the FITC approximation for non-Gaussian likelihoods for EP and Laplace's approximation. New likelihood functions: mixture likelihood, Poisson likelihood, label noise. We added two MCMC samplers.


Logo NaN toolbox 2.5.2

by schloegl - February 10, 2012, 11:45:52 CET [ Project Homepage BibTeX Download ] 21501 views, 4096 downloads, 1 subscription

About: NaN-toolbox is a statistics and machine learning toolbox for handling data with and without missing values.

Changes:

Changes in v.2.5.2 - faster version of quantile if multiple quantiles are requested - removes the dependency on ZLIB and thus - fixes "pkg install nan" for Octave on Windows - a number of minor improvements

For details see the CHANGELOG at http://pub.ist.ac.at/~schloegl/matlab/NaN/CHANGELOG


About: The glm-ie toolbox contains scalable estimation routines for GLMs (generalised linear models) and SLMs (sparse linear models) as well as an implementation of a scalable convex variational Bayesian inference relaxation. We designed the glm-ie package to be simple, generic and easily expansible. Most of the code is written in Matlab including some MEX files. The code is fully compatible to both Matlab 7.x and GNU Octave 3.2.x. Probabilistic classification, sparse linear modelling and logistic regression are covered in a common algorithmical framework allowing for both MAP estimation and approximate Bayesian inference.

Changes:

contributed by George Papandreou:

  • preconditioning support in the inf/linsolve_lcg.m CG routine.

  • @matConv2 and @matFD2 support different boundary conditions in deblurring

  • various mat/@*/diagFAtAFt.m support circulant preconditioning

  • bugfixes in nonnegativity option in pls/plsLBFGS.m and pen/penVBNorm.m when used together with EP

  • inf/diag_inv_sample.m, a Monte Carlo estimator

gfortran support to pls/lbfgsb/Makefile (thanks to Ernst Kloppenburg)

slight modification to mat/@matFFTN/mvm.m to make it more consistent

simple gradient solver using Barzilai-Borwein step size pls/plsBB.m
