Lower bounds for the integrality gap of the bi-directed cut formulation of the Steiner Tree Problem
Ambrogio Maria Bernardelli, Eleonora Vercesi, Stefano Gualandi +2
In this work, we study the metric Steiner Tree problem on graphs focusing on computing lower bounds for the integrality gap of the bi-directed cut (BCR) formulation and introducing…
An Ant Colony System for the Team Orienteering Problem with Time Windows
Roberto Montemanni, Luca Maria Gambardella
This paper discusses a heuristic approach for Team Orienteering Problems with Time Windows. The method we propose takes advantage of a solution model based on a hierarchic generali…
Challenges in Visual Anomaly Detection for Mobile Robots
Dario Mantegazza, Alessandro Giusti, Luca M. Gambardella +2
We consider the task of detecting anomalies for autonomous mobile robots based on vision. We categorize relevant types of visual anomalies and discuss how they can be detected by u…
An Outlier Exposure Approach to Improve Visual Anomaly Detection Performance for Mobile Robots
Dario Mantegazza, Alessandro Giusti, Luca Maria Gambardella +1
We consider the problem of building visual anomaly detection systems for mobile robots. Standard anomaly detection models are trained using large datasets composed only of non-anom…
Training Lightweight CNNs for Human-Nanodrone Proximity Interaction from Small Datasets using Background Randomization
Marco Ferri, Dario Mantegazza, Elia Cereda +5
We consider the task of visually estimating the pose of a human from images acquired by a nearby nano-drone; in this context, we propose a data augmentation approach based on synth…
Sensing Anomalies as Potential Hazards: Datasets and Benchmarks
Dario Mantegazza, Carlos Redondo, Fran Espada +3
We consider the problem of detecting, in the visual sensing data stream of an autonomous mobile robot, semantic patterns that are unusual (i.e., anomalous) with respect to the robo…
