DiME: Maximizing Mutual Information by a Difference of Matrix-Based Entropies

1 code implementation19 Jan 2023 Oscar Skean, Jhoan Keider Hoyos Osorio, Austin J. Brockmeier, Luis Gonzalo Sanchez Giraldo

We introduce an information-theoretic quantity with similar properties to mutual information that can be estimated from data without making explicit assumptions on the underlying distribution.

The Representation Jensen-Rényi Divergence

1 code implementation2 Dec 2021 Jhoan Keider Hoyos Osorio, Oscar Skean, Austin J. Brockmeier, Luis Gonzalo Sanchez Giraldo

We introduce a divergence measure between data distributions based on operators in reproducing kernel Hilbert spaces defined by kernels.

Max-sliced Bures Distance for Interpreting Discrepancies

no code implementations1 Jan 2021 Austin J. Brockmeier, Claudio Cesar Claros, Carlos H. Mendoza-Cardenas, Yüksel Karahan, Matthew S. Emigh, Luis Gonzalo Sanchez Giraldo

We propose the max-sliced Bures distance, a lower bound on the max-sliced Wasserstein-2 distance, to identify the instances associated with the maximum discrepancy between two samples.

Multivariate Extension of Matrix-based Renyi's α-order Entropy Functional

1 code implementation23 Aug 2018 Shujian Yu, Luis Gonzalo Sanchez Giraldo, Robert Jenssen, Jose C. Principe

The matrix-based Renyi's \alpha-order entropy functional was recently introduced using the normalized eigenspectrum of a Hermitian matrix of the projected data in a reproducing kernel Hilbert space (RKHS).

Integrating Flexible Normalization into Mid-Level Representations of Deep Convolutional Neural Networks

no code implementations5 Jun 2018 Luis Gonzalo Sanchez Giraldo, Odelia Schwartz

Deep convolutional neural networks (CNNs) are becoming increasingly popular models to predict neural responses in visual cortex.
