A geometric spectral sequence in Khovanov homology
The aim of this paper is to introduce and study a geometric spectral sequence
in Khovanov homology. The construction was motivated by a similar spectral
sequence from Khovanov homology to Heegaard Floer homology.Comment: 37 pages, 24 figures, minor revision
Information Theoretical Estimators Toolbox
We present ITE (information theoretical estimators) a free and open source,
multi-platform, Matlab/Octave toolbox that 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. ITE also includes a prototype
application in a central problem class of signal processing, independent
subspace analysis and its extensions.Comment: 5 pages; ITE toolbox: https://bitbucket.org/szzoli/ite
