On the Centroids of Symmetrized Bregman Divergences
In this paper, we generalize the notions of centroids and barycenters to the broad class of information-theoretic distortion measures called Bregman divergences. Bregman divergences are versatile, and unify quadratic geometric distances with various statistical entropic measures.

Total Jensen divergences: Definition, Properties and k-Means++ Clustering
We present a novel class of divergences induced by a smooth convex function called total Jensen divergences. Those total Jensen divergences are invariant by construction to rotations, a feature yielding regularization of ordinary Jensen divergences by a ...

Proper scoring rules and Bregman divergence
We revisit the mathematical foundations of proper scoring rules (PSRs) and Bregman divergences and present their characteristic properties in a unified theoretical framework. In many situations it is preferable not to generate a PSR directly from its convex entropy on the unit simplex but instead by the sublinear extension of the entropy to the ...

Fixed point theory is a rapidly developing area of mathematics that provides a unifying perspective across topology, optimization, and analysis. Classical theorems such as Brower’s, Banach’s contraction principle, Schauder’s topological theorems, and ...

Approximation Algorithms for Bregman Co-clustering and Tensor Clustering
In the past few years powerful generalizations to the Euclidean k-means problem have been made, such as Bregman clustering [7], co-clustering (i.e., simultaneous clustering of rows and columns of an input matrix) [9,18], and tensor clustering [8,34 ...

The Bregman Variational Dual-Tree Framework
Graph-based methods provide a powerful tool set for many non-parametric frameworks in Machine Learning. In general, the memory and computational complexity of these methods is quadratic in the number of examples in the data which makes them quickly ...
