Interpretable Ensembles of Local Models for Safety-Related Applications
Sebastian Nusser, Clemens Otte, Werner Hauptmann · 2008
Abstract. This paper discusses a machine learning approach for binary classification problems which satisfies the specific requirements of safety-related applications. The approach is based on ensembles of local models. Each local model utilizes only a small subspace of the complete input space. This ensures the interpretability and verifiability of the local models, which is a crucial prerequisite for applications in safety-related domains. A feature construction method based on a multi-layer perceptron architecture is proposed to overcome limitations of the local modeling strategy, while keeping the global model interpretable. 1
