ReliableNet: A Chance-Constrained Approach to Trustworthy Classification in Deep Learning

Ange-Clément Akazan, Ineza Remy Mugenga, Abebe Geletu +2

A prediction that is both confident and wrong is a critical reliability failure because it can bypass abstention and human review precisely when the model is mistaken. Empirical ri…

RRaPINNs: Residual Risk-Aware Physics Informed Neural Networks

Ange-Clément Akazan, Issa Karambal, Jean Medard Ngnotchouye +1

Physics-informed neural networks (PINNs) typically minimize average residuals, which can conceal large, localized errors. We propose Residual Risk-Aware Physics-Informed Neural Net…

The Reflexive Integrated Information Unit: A Differentiable Primitive for Artificial Consciousness

Gnankan Landry Regis N'guessan, Issa Karambal

Research on artificial consciousness lacks the equivalent of the perceptron: a small, trainable module that can be copied, benchmarked, and iteratively improved. We introduce the R…
