Differential Privacy for Anomaly Detection: Analyzing the Trade-off Between Privacy and Explainability

no code implementations9 Apr 2024 Fatima Ezzeddine, Mirna Saad, Omran Ayoub, Davide Andreoletti, Martin Gjoreski, Ihab Sbeity, Marc Langheinrich, Silvia Giordano

Anomaly detection (AD), also referred to as outlier detection, is a statistical process aimed at identifying observations within a dataset that significantly deviate from the expected pattern of the majority of the data.

Liquid Neural Network-based Adaptive Learning vs. Incremental Learning for Link Load Prediction amid Concept Drift due to Network Failures

no code implementations8 Apr 2024 Omran Ayoub, Davide Andreoletti, Aleksandra Knapińska, Róża Goścień, Piotr Lechowicz, Tiziano Leidi, Silvia Giordano, Cristina Rottondi, Krzysztof Walkowiak

In this work, we address this challenge for the problem of traffic forecasting and propose an approach that exploits adaptive learning algorithms, namely, liquid neural networks, which are capable of self-adaptation to abrupt changes in data patterns without requiring any retraining.

Knowledge Distillation-Based Model Extraction Attack using Private Counterfactual Explanations

no code implementations4 Apr 2024 Fatima Ezzeddine, Omran Ayoub, Silvia Giordano

To this end, we first propose a novel MEA methodology based on Knowledge Distillation (KD) to enhance the efficiency of extracting a substitute model of a target model exploiting CFs.
