Logo JMLR Information Theoretical Estimators 0.57

by szzoli - April 10, 2014, 18:35:22 CET [ Project Homepage BibTeX BibTeX for corresponding Paper Download ] 32481 views, 6998 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:
  • Kullback-Leibler divergence estimation based on maximum likelihood estimation + analytical formula in the chosen exponential family: added.

  • A new sampling based entropy estimator with KDE correction on the left/right sides: added.

  • Quick tests: updated with the new estimators.

About: Somoclu is a massively parallel implementation of self-organizing maps. It relies on OpenMP for multicore execution, MPI for distributing the workload, and it can be accelerated by CUDA on a GPU cluster. A sparse kernel is also included, which is useful for training maps on vector spaces generated in text mining processes.

Changes:
  • Initial Windows support through GCC on Windows.
  • Better I/O separation for the Python, R, and MATLAB interfaces.
  • Bug fixes: major MPI initialization bug fixed.
