Logo revrand 0.3

by dsteinberg - April 29, 2016, 07:31:27 CET [ Project Homepage BibTeX Download ] 1235 views, 242 downloads, 3 subscriptions

About: A library of scalable Bayesian generalised linear models with fancy features

Changes:
  • Simplification of all of the algorithm interfaces by using Parameter (bounded) types
  • Re-factoring of the modules in the library to make it more user friendly

Logo hca 0.63

by wbuntine - April 26, 2016, 15:35:03 CET [ Project Homepage BibTeX BibTeX for corresponding Paper Download ] 14879 views, 2391 downloads, 4 subscriptions

About: Multi-core non-parametric and bursty topic models (HDP-LDA, DCMLDA, and other variants of LDA) implemented in C using efficient Gibbs sampling, with hyperparameter sampling and other flexible controls.

Changes:

Corrected the new normalised Gamma model for topics so it works with multicore. Improvements to documentation. Added an asymptotic version of the generalised Stirling numbers so it longer fails when they run out of bounds on bigger data.

About: Armadillo is a high quality C++ linear algebra library, aiming towards a good balance between speed and ease of use. The function syntax is deliberately similar to MATLAB. Useful for algorithm development directly in C++, or quick conversion of research code into production environments (eg. software & hardware products).

Changes:
  • added trapz() for numerical integration
  • added logmat() for calcuating the matrix logarithm
  • added approx_equal() for determining approximate equality
  • added regspace() for generating vectors with regularly spaced elements
  • added logspace() for generating vectors with logarithmically spaced elements
  • expanded .save() and .load() with hdf5_binary_trans file type, to save/load data with columns transposed to rows
  • fixes for trunc_log() and trunc_exp()

Logo AMIDST Toolbox 0.4.1

by ana - April 20, 2016, 09:44:23 CET [ Project Homepage BibTeX BibTeX for corresponding Paper Download ] 1118 views, 110 downloads, 4 subscriptions

About: A java library for the analysis of data streams with probabilistic graphical models. AMIDST provides parallel multi-core implementations of Bayesian parameter learning algorithms using variational message passing and importance sampling for static and dynamic Bayesian networks. Additionally, AMIDST efficiently leverages existing functionalities and algorithms by interfacing to software tools such as Weka, Moa, HUGIN and R.

Changes:
  • Bugs fixed.
  • Improved usability.

Logo JMLR Information Theoretical Estimators 0.62

by szzoli - April 17, 2016, 17:19:00 CET [ Project Homepage BibTeX BibTeX for corresponding Paper Download ] 96341 views, 18792 downloads, 2 subscriptions

About: ITE (Information Theoretical Estimators) is capable of estimating many different variants of entropy, mutual information, divergence, association measures, cross quantities and kernels on distributions. 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:
  • Von Mises expansion based estimators: included for 7 unconditional quantities (Shannon entropy, Shannon mutual information, Kullback-Leibler divergence, Rényi divergence, Tsallis divergence, Pearson Chi^2 divergence, Hellinger distance.

  • Analytical value (for Gaussian random variables) and quick test: added for the Hellinger distance.

About: A Tool for Measuring String Similarity

Changes:

This release fixes the incorrect implementation of the bag distance.


About: TBEEF, a doubly ensemble framework for recommendation and prediction problems.

Changes:

Included the final technical report.
