On the Rényi Cross-Entropy

no code implementations28 Jun 2022 Ferenc Cole Thierrin, Fady Alajaji, Tamás Linder

The R\'{e}nyi cross-entropy measure between two distributions, a generalization of the Shannon cross-entropy, was recently used as a loss function for the improved design of deep learning generative adversarial networks.

Achieving Utility, Fairness, and Compactness via Tunable Information Bottleneck Measures

no code implementations20 Jun 2022 Adam Gronowski, William Paul, Fady Alajaji, Bahman Gharesifard, Philippe Burlina

Designing machine learning algorithms that are accurate yet fair, not discriminating based on any sensitive attribute, is of paramount importance for society to accept AI for critical applications.

Renyi Fair Information Bottleneck for Image Classification

no code implementations9 Mar 2022 Adam Gronowski, William Paul, Fady Alajaji, Bahman Gharesifard, Philippe Burlina

We develop a novel method for ensuring fairness in machine learning which we term as the Renyi Fair Information Bottleneck (RFIB).

Least $k$th-Order and Rényi Generative Adversarial Networks

no code implementations3 Jun 2020 Himesh Bhatia, William Paul, Fady Alajaji, Bahman Gharesifard, Philippe Burlina

Another novel GAN generator loss function is next proposed in terms of R\'{e}nyi cross-entropy functionals with order $\alpha >0$, $\alpha\neq 1$.


Unsupervised Discovery, Control, and Disentanglement of Semantic Attributes with Applications to Anomaly Detection

no code implementations25 Feb 2020 William Paul, I-Jeng Wang, Fady Alajaji, Philippe Burlina

Our work focuses on unsupervised and generative methods that address the following goals: (a) learning unsupervised generative representations that discover latent factors controlling image semantic attributes, (b) studying how this ability to control attributes formally relates to the issue of latent factor disentanglement, clarifying related but dissimilar concepts that had been confounded in the past, and (c) developing anomaly detection methods that leverage representations learned in (a).

Capacity of Generalized Discrete-Memoryless Push-to-Talk Two-Way Channels

no code implementations2 Apr 2019 Jian-Jia Weng, Fady Alajaji, Tamás Linder

In this report, we generalize Shannon's push-to-talk two-way channel (PTT-TWC) by allowing reliable full-duplex transmission as well as noisy reception in the half-duplex (PTT) mode.

Information Extraction Under Privacy Constraints

no code implementations7 Nov 2015 Shahab Asoodeh, Mario Diaz, Fady Alajaji, Tamás Linder

To this end, the so-called {\em rate-privacy function} is introduced to quantify the maximal amount of information (measured in terms of mutual information) that can be extracted from $Y$ under a privacy constraint between $X$ and the extracted information, where privacy is measured using either mutual information or maximal correlation.
