A Robust Prototype-Based Network with Interpretable RBF Classifier Foundations

AAAI 2025technical

Prototype-based classification learning methods are known to be inherently interpretable. However, this paradigm suffers from major limitations compared to deep models, such as lower performance. This led to the development of the so-called deep Prototype-Based Networks (PBNs), also known as prototy…

Fast Adversarial Robustness Certification of Nearest Prototype Classifiers for Arbitrary Seminorms

NeurIPS 2020poster

Methods for adversarial robustness certification aim to provide an upper bound on the test error of a classifier under adversarial manipulation of its input. Current certification methods are computationally expensive and limited to attacks that optimize the manipulation with respect to a norm. We o…

Classification-by-Components: Probabilistic Modeling of Reasoning over a Set of Components

NeurIPS 2019poster

Abstract Neural networks are state-of-the-art classification approaches but are generally difficult to interpret. This issue can be partly alleviated by constructing a precise decision process within the neural network. In this work, a network architecture, denoted as Classification-By-Components ne…
