Mining Matrix Data with Bregman Matrix Divergences for Portfolio Selectionivergences. There has recently been a burst of attention in on-line learning to learn portfolios having limited risk in Markowitz’ setting. In an on-line framework, we then tackle the problem of finding adaptive portfolio strategies based on our generalized model. We devise a learning algorithm base

Learning Mixtures by Simplifying Kernel Density Estimatorsly on divergences and centroids computation and we use two different divergences (and their associated centroids), Bregman and . Along with the description of the algorithms, we describe the pyMEF =library=, which is a Python library designed for the manipulation of mixture of exponential families.

For some topics, we have placed a little more emphasis on the algorithms. For other topics, where the mathemati
