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.

The Evolving Causal Structure of Equity Risk Factors

no code implementations9 Nov 2021 Gabriele D'Acunto, Paolo Bajardi, Francesco Bonchi, Gianmarco De Francisci Morales

They link the evolution of the causal structure of equity risk factors with market volatility and a worsening macroeconomic environment, and show that, in times of financial crisis, exposure to different factors boils down to exposure to the market risk factor.

Patterns of Routes of Administration and Drug Tampering for Nonmedical Opioid Consumption: Data Mining and Content Analysis of Reddit Discussions

no code implementations22 Feb 2021 Duilio Balsamo, Paolo Bajardi, Alberto Salomone, Rossano Schifanella

We aimed to find a large cohort of Reddit users interested in discussing the use of opioids, trace the temporal evolution of their interest, and extensively characterize patterns of the nonmedical consumption of opioids, with a focus on routes of administration and drug tampering.
