Continuous approximation of collective system behaviour: A tutorial

L Bortolussi, J Hillston, D Latella, M Massink - Performance Evaluation, 2013 - Elsevier
In this paper we present an overview of the field of deterministic approximation of Markov
processes, both in discrete and continuous times. We will discuss mean field approximation of …

Data-driven statistical learning of temporal logic properties

E Bartocci, L Bortolussi, G Sanguinetti - … on formal modeling and analysis of …, 2014 - Springer
We present a novel approach to learn logical formulae characterising the emergent behaviour
of a dynamical system from system observations. At a high level, the approach starts by …

[HTML][HTML] System design of stochastic models using robustness of temporal properties

E Bartocci, L Bortolussi, L Nenzi… - Theoretical Computer …, 2015 - Elsevier
l can be condensed into an update vector v l , giving the net change in population variables
due to η l : v l … Additionally, each reaction η l has an associated rate function f l ( X ) giving the …

[HTML][HTML] Smoothed model checking for uncertain continuous-time Markov chains

L Bortolussi, D Milios, G Sanguinetti - Information and Computation, 2016 - Elsevier
We consider the problem of computing the satisfaction probability of a formula for stochastic
models with parametric uncertainty. We show that this satisfaction probability is a smooth …

Robustness of bayesian neural networks to gradient-based attacks

…, L Laurenti, A Patane, L Bortolussi… - Advances in …, 2020 - proceedings.neurips.cc
Vulnerability to adversarial attacks is one of the principal hurdles to the adoption of deep
learning in safety-critical applications. Despite significant efforts, both practical and theoretical, …

Qualitative and quantitative monitoring of spatio-temporal properties

L Nenzi, L Bortolussi, V Ciancia, M Loreti… - Runtime Verification: 6th …, 2015 - Springer
We address the specification and verification of spatio-temporal behaviours of complex
systems, extending Signal Spatio-Temporal Logic (SSTL) with a spatial operator capable of …

Monitoring mobile and spatially distributed cyber-physical systems

E Bartocci, L Bortolussi, M Loreti, L Nenzi - Proceedings of the 15th ACM …, 2017 - dl.acm.org
… We say thatσ is piecewise constant when for any , σ() is a … s such that s() = σ()(t), for any
L. Different kinds of signals … In the rest of the paper we will use ⃗x(,t) to denote ⃗x()(t). …

On the robustness of temporal properties for stochastic models

[HTML][HTML] Dysferlinopathy course and sportive activity: clues for possible treatment

C Angelini, E Peterle, A Gaiani, L Bortolussi… - Acta …, 2011 - ncbi.nlm.nih.gov
LGMD2B is a frequent proximo-distal myopathy with rapid evolution after age 20. Exacerbating
factors may be physical exercise and inflammation. There is very little information about …

A robust genetic algorithm for learning temporal specifications from data

L Nenzi, S Silvetti, E Bartocci, L Bortolussi - Quantitative Evaluation of …, 2018 - Springer
We consider the problem of mining signal temporal logical requirements from a dataset of
regular (good) and anomalous (bad) trajectories of a dynamical system. We assume the …
