Targeted Adversarial Attacks against Neural Network Trajectory Predictors

no code implementations8 Dec 2022 Kaiyuan Tan, Jun Wang, Yiannis Kantaros

To bridge this gap, in this paper, we propose a targeted adversarial attack against DNN models for trajectory forecasting tasks.

Accelerated Reinforcement Learning for Temporal Logic Control Objectives

no code implementations9 May 2022 Yiannis Kantaros

To address this problem, we propose a novel accelerated model-based reinforcement learning (RL) algorithm for LTL control objectives that is capable of learning control policies significantly faster than related approaches.

Planning and Control of Multi-Robot-Object Systems under Temporal Logic Tasks and Uncertain Dynamics

no code implementations25 Apr 2022 Christos K. Verginis, Yiannis Kantaros, Dimos V. Dimarogonas

We achieve such a construction by designing appropriate adaptive control protocols in the lower level, which guarantee the safe robot navigation/object transportation in the environment while compensating for the dynamic uncertainties.

Model-Based Robust Adaptive Semantic Segmentation

no code implementations29 Sep 2021 Jun Wang, Yiannis Kantaros

To mitigate this challenge, in this paper, we propose model-based robust adaptive training algorithm (MRTAdapt), a new training algorithm to enhance the robustness of DNN-based semantic segmentation methods against natural variations that leverages model-based robust training algorithms and generative adversarial networks.

A Temporal Logic-Based Hierarchical Network Connectivity Controller

no code implementations1 Sep 2020 Hans Riess, Yiannis Kantaros, George Pappas, Robert Ghrist

We show that these constraints along with the requirement of propagating information in the network can be captured by a Linear Temporal Logic (LTL) framework.

Real-Time Detectors for Digital and Physical Adversarial Inputs to Perception Systems

no code implementations23 Feb 2020 Yiannis Kantaros, Taylor Carpenter, Kaustubh Sridhar, Yahan Yang, Insup Lee, James Weimer

To highlight this, we demonstrate the efficiency of the proposed detector on ImageNet, a task that is computationally challenging for the majority of relevant defenses, and on physically attacked traffic signs that may be encountered in real-time autonomy applications.

Reinforcement Learning for Temporal Logic Control Synthesis with Probabilistic Satisfaction Guarantees
