Assessing the trade-off between prediction accuracy and interpretability for topic modeling on energetic materials corpora

no code implementations1 Jun 2022 Monica Puerto, Mason Kellett, Rodanthi Nikopoulou, Mark D. Fuge, Ruth Doherty, Peter W. Chung, Zois Boukouvalas

With our accuracy results, we also introduce local interpretability model-agnostic explanations (LIME) of each prediction to provide a localized understanding of each prediction and to validate classifier decisions with our team of energetics experts.

Development of ICA and IVA Algorithms with Application to Medical Image Analysis

no code implementations25 Jan 2018 Zois Boukouvalas

In this work, we first introduce a flexible ICA algorithm that uses an effective PDF estimator to accurately capture the underlying statistical properties of the data.

Independent Component Analysis by Entropy Maximization with Kernels

no code implementations22 Oct 2016 Zois Boukouvalas, Rami Mowakeaa, Geng-Shen Fu, Tulay Adali

ICA algorithms cast in the ML framework often deviate from its theoretical optimality properties due to poor estimation of the source PDF.
