An Energy-Aware Approach to Design Self-Adaptive AI-based Applications on the Edge

1 code implementation31 Aug 2023 Alessandro Tundo, Marco Mobilio, Shashikant Ilager, Ivona Brandić, Ezio Bartocci, Leonardo Mariani

In this paper, we present an energy-aware approach for the design and deployment of self-adaptive AI-based applications that can balance application objectives (e. g., accuracy in object detection and frames processing rate) with energy consumption.

Deductive Controller Synthesis for Probabilistic Hyperproperties

no code implementations10 Jul 2023 Roman Andriushchenko, Ezio Bartocci, Milan Ceska, Francesco Pontiggia, Sarah Sallinger

Our specification language builds on top of the logic HyperPCTL and enhances it with structural constraints over the synthesized controllers.

DeepSTL -- From English Requirements to Signal Temporal Logic

no code implementations21 Sep 2021 Jie He, Ezio Bartocci, Dejan Ničković, Haris Isakovic, Radu Grosu

In this paper we propose DeepSTL, a tool and technique for the translation of informal requirements, given as free English sentences, into Signal Temporal Logic (STL), a formal specification language for cyber-physical systems, used both by academia and advanced research labs in industry.

Neural Network-based Control for Multi-Agent Systems from Spatio-Temporal Specifications

no code implementations6 Apr 2021 Suhail Alsalehi, Noushin Mehdipour, Ezio Bartocci, Calin Belta

We propose a framework for solving control synthesis problems for multi-agent networked systems required to satisfy spatio-temporal specifications.

Predictive Monitoring with Logic-Calibrated Uncertainty for Cyber-Physical Systems

no code implementations31 Oct 2020 Meiyi Ma, John Stankovic, Ezio Bartocci, Lu Feng

We develop a novel approach for monitoring sequential predictions generated from Bayesian Recurrent Neural Networks (RNNs) that can capture the inherent uncertainty in CPS, drawing on insights from our study of real-world CPS datasets.

Analysis of Bayesian Networks via Prob-Solvable Loops

no code implementations18 Jul 2020 Ezio Bartocci, Laura Kovács, Miroslav Stankovič

Prob-solvable loops are probabilistic programs with polynomial assignments over random variables and parametrised distributions, for which the full automation of moment-based invariant generation is decidable.

Control from Signal Temporal Logic Specifications with Smooth Cumulative Quantitative Semantics

1 code implementation25 Apr 2019 Iman Haghighi, Noushin Mehdipour, Ezio Bartocci, Calin Belta

We present a framework to synthesize control policies for nonlinear dynamical systems from complex temporal constraints specified in a rich temporal logic called Signal Temporal Logic (STL).

A Roadmap Towards Resilient Internet of Things for Cyber-Physical Systems

no code implementations16 Oct 2018 Denise Ratasich, Faiq Khalid, Florian Geissler, Radu Grosu, Muhammad Shafique, Ezio Bartocci

Furthermore, this paper presents the main challenges in building a resilient IoT for CPS which is crucial in the era of smart CPS with enhanced connectivity (an excellent example of such a system is connected autonomous vehicles).

A Robust Genetic Algorithm for Learning Temporal Specifications from Data

no code implementations13 Nov 2017 Laura Nenzi, Simone Silvetti, Ezio Bartocci, Luca Bortolussi

We consider the problem of mining signal temporal logical requirements from a dataset of regular (good) and anomalous (bad) trajectories of a dynamical system.

ARES: Adaptive Receding-Horizon Synthesis of Optimal Plans

no code implementations21 Dec 2016 Anna Lukina, Lukas Esterle, Christian Hirsch, Ezio Bartocci, Junxing Yang, Ashish Tiwari, Scott A. Smolka, Radu Grosu

Inspired by Importance Splitting, the length of the horizon and the number of particles are chosen such that at least one particle reaches a next-level state, that is, a state where the cost decreases by a required delta from the previous-level state.

Temporal Logic as Filtering

1 code implementation27 Oct 2015 Alena Rodionova, Ezio Bartocci, Dejan Nickovic, Radu Grosu

We also provide a quantitative semantics for MTL, which measures the normalized, maximum number of times a formula is satisfied within its associated kernel, by a given signal.

Deep Neural Programs for Adaptive Control in Cyber-Physical Systems

no code implementations13 Feb 2015 Konstantin Selyunin, Denise Ratasich, Ezio Bartocci, Radu Grosu

We introduce Deep Neural Programs (DNP), a novel programming paradigm for writing adaptive controllers for cy-ber-physical systems (CPS).

A Formal Methods Approach to Pattern Synthesis in Reaction Diffusion Systems

no code implementations12 Sep 2014 Ebru Aydin Gol, Ezio Bartocci, Calin Belta

We propose a technique to detect and generate patterns in a network of locally interacting dynamical systems.

Learning Temporal Logical Properties Discriminating ECG models of Cardiac Arrhytmias

no code implementations29 Dec 2013 Ezio Bartocci, Luca Bortolussi, Guido Sanguinetti

We present a novel approach to learn the formulae characterising the emergent behaviour of a dynamical system from system observations.

On the Robustness of Temporal Properties for Stochastic Models

no code implementations3 Sep 2013 Ezio Bartocci, Luca Bortolussi, Laura Nenzi, Guido Sanguinetti

By discussing two examples, we show how to approximate the distribution of the robustness score and its key indicators: the average robustness and the conditional average robustness.

Monitoring with uncertainty

no code implementations24 Aug 2013 Ezio Bartocci, Radu Grosu

We discuss the problem of runtime verification of an instrumented program that misses to emit and to monitor some events.
