Exploiting auto-encoders and segmentation methods for middle-level explanations of image classification systems

no code implementations9 Jun 2021 Andrea Apicella, Salvatore Giugliano, Francesco Isgrò, Roberto Prevete

We start from the hypothesis that some autoencoders, relying on standard data representation approaches, could extract more salient and understandable input properties, which we call here \textit{Middle-Level input Features} (MLFs), for a user with respect to raw low-level features.

Adaptive Filters in Graph Convolutional Neural Networks

no code implementations21 May 2021 Andrea Apicella, Francesco Isgrò, Andrea Pollastro, Roberto Prevete

Over the last few years, we have witnessed the availability of an increasing data generated from non-Euclidean domains, which are usually represented as graphs with complex relationships, and Graph Neural Networks (GNN) have gained a high interest because of their potential in processing graph-structured data.

A general approach to compute the relevance of middle-level input features

no code implementations16 Oct 2020 Andrea Apicella, Salvatore Giugliano, Francesco Isgrò, Roberto Prevete

This work proposes a novel general framework, in the context of eXplainable Artificial Intelligence (XAI), to construct explanations for the behaviour of Machine Learning (ML) models in terms of middle-level features.
