dc.description.abstractInformation measures have long been studied in the context of hypothesis testing leading to variety of bounds on performance based on the information content of a signal or the divergence between distributions. Here we consider the problem of estimation of information content for high-dimensional signals for purposes of classification. Direct estimation of information for high-dimensional signals is generally not tractable therefore we consider an extension to a method first suggested in (J.W. Fisher III and J.C. Principle, 1998) in which high dimensional signals are mapped to lower dimensional feature spaces yielding lower bounds on information content. We develop an affine-invariant gradient method and examine the utility of the resulting estimates for predicting classification performance empirically.en_US
