Activation Functions for Generalized Learning Vector Quantization - A Performance Comparison

Autor: Villmann, Thomas, Ravichandran, John, Villmann, Andrea, Nebel, David, Kaden, Marika

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. Prototype-based classification learning metho

We consider a reject option for prototype-based Learning Vector Quantization LVQ, which facilitates the detection of outliers in the data during the classification process. The rejection mechanism is based on a distance-based criterion and the corres

In this contribution, we focus on reject options for prototype-based classifiers, and we present a comparison of reject options based on statistical models for prototype-based classification as compared to alternatives which are motivated by simple g
