A Formal Resilience Framework for Cyber-Physical Embodied Systems under Device-Level Cyberattacks
Alberto Giaretta
In cyber-physical systems (CPSs), fault tolerance is traditionally achieved by analysing sensor and actuator outputs, detecting progressive drift or sudden failures, and initiating…
Refusal Before Decoding: Detecting and Exploiting Refusal Signals in Intermediate LLM Activations
Matteo Gioele Collu, Riccardo Conte, Alberto Giaretta +4
In this paper, we investigate whether refusal behavior can be predicted from LLM intermediate activations before decoding using linear probes trained on residual stream activations…
From Chat Control to Robot Control: Implications of the Chat Control Proposal for Human-Robot Interaction
Neziha Akalin, Alberto Giaretta
This paper explores how a recent European Union proposal, the so-called Chat Control, which creates regulatory incentives for providers to implement content detection and communica…
From Vulnerabilities to Remediation: A Systematic Literature Review of LLMs in Code Security
Enna Basic, Alberto Giaretta
Large Language Models (LLMs) have emerged as powerful tools for automating programming tasks, including security-related ones. However, they can also introduce vulnerabilities duri…
Learning stochasticity: a nonparametric framework for intrinsic noise estimation
Gianluigi Pillonetto, Alberto Giaretta, Mauro Bisiacco
Understanding the principles that govern dynamical systems is a central challenge across many scientific domains, including biology and ecology. Incomplete knowledge of nonlinear i…
Sparse and nonparametric estimation of equations governing dynamical systems with applications to biology
G. Pillonetto, A. Giaretta, A. Aravkin +2
Data-driven discovery of model equations is a powerful approach for understanding the behavior of dynamical systems in many scientific fields. In particular, the ability to learn m…
