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

1 code implementation NeurIPS 2019 Sascha Saralajew, Lars Holdijk, Maike Rees, Ebubekir Asan, Thomas Villmann

The decomposition of objects into generic components combined with the probabilistic reasoning provides by design a clear interpretation of the classification decision process.

Robustness of Generalized Learning Vector Quantization Models against Adversarial Attacks

1 code implementation1 Feb 2019 Sascha Saralajew, Lars Holdijk, Maike Rees, Thomas Villmann

The evaluation suggests that both Generalized LVQ and Generalized Tangent LVQ have a high base robustness, on par with the current state-of-the-art in robust neural network methods.

Activation Functions for Generalized Learning Vector Quantization - A Performance Comparison

no code implementations17 Jan 2019 Thomas Villmann, John Ravichandran, Andrea Villmann, David Nebel, Marika Kaden

An appropriate choice of the activation function (like ReLU, sigmoid or swish) plays an important role in the performance of (deep) multilayer perceptrons (MLP) for classification and regression learning.

Regularization in Relevance Learning Vector Quantization Using l one Norms

no code implementations18 Oct 2013 Martin Riedel, Marika Kästner, Fabrice Rossi, Thomas Villmann

We propose in this contribution a method for l one regularization in prototype based relevance learning vector quantization (LVQ) for sparse relevance profiles.
