HOLMES: HOLonym-MEronym based Semantic inspection for Convolutional Image Classifiers

1 code implementation13 Mar 2024 Francesco Dibitonto, Fabio Garcea, André Panisson, Alan Perotti, Lia Morra

Convolutional Neural Networks (CNNs) are nowadays the model of choice in Computer Vision, thanks to their ability to automatize the feature extraction process in visual tasks.

DINE: Dimensional Interpretability of Node Embeddings

no code implementations2 Oct 2023 Simone Piaggesi, Megha Khosla, André Panisson, Avishek Anand

Towards that, we first develop new metrics that measure the global interpretability of embedding vectors based on the marginal contribution of the embedding dimensions to predicting graph structure.

Beyond One-Hot-Encoding: Injecting Semantics to Drive Image Classifiers

1 code implementation1 Aug 2023 Alan Perotti, Simone Bertolotto, Eliana Pastor, André Panisson

Finally, we discuss how this approach can be further exploited in terms of explainability and adversarial robustness.

Fast and Effective GNN Training with Linearized Random Spanning Trees

no code implementations7 Jun 2023 Francesco Bonchi, Claudio Gentile, Francesco Paolo Nerini, André Panisson, Fabio Vitale

We present a new effective and scalable framework for training GNNs in node classification tasks, based on the effective resistance, a powerful tool solidly rooted in graph theory.

GRAPHSHAP: Explaining Identity-Aware Graph Classifiers Through the Language of Motifs

no code implementations17 Feb 2022 Alan Perotti, Paolo Bajardi, Francesco Bonchi, André Panisson

Decoupling the feature space (edges) from a desired high-level explanation language (such as motifs) is thus a major challenge towards developing actionable explanations for graph classification tasks.

Time-varying Graph Representation Learning via Higher-Order Skip-Gram with Negative Sampling

1 code implementation25 Jun 2020 Simone Piaggesi, André Panisson

Representation learning models for graphs are a successful family of techniques that project nodes into feature spaces that can be exploited by other machine learning algorithms.
