SOAP: Cross-sensor Domain Adaptation for 3D Object Detection Using Stationary Object Aggregation Pseudo-labelling

no code implementations8 Jan 2024 Chengjie Huang, Vahdat Abdelzad, Sean Sedwards, Krzysztof Czarnecki

We consider the problem of cross-sensor domain adaptation in the context of LiDAR-based 3D object detection and propose Stationary Object Aggregation Pseudo-labelling (SOAP) to generate high quality pseudo-labels for stationary objects.

Recursive Constraints to Prevent Instability in Constrained Reinforcement Learning

no code implementations20 Jan 2022 Jaeyoung Lee, Sean Sedwards, Krzysztof Czarnecki

In this work, after describing and motivating our problem with a simple example, we present a suitable constrained reinforcement learning algorithm that prevents learning instability, using recursive constraints.

Fast Falsification of Hybrid Systems using Probabilistically Adaptive Input

1 code implementation11 Dec 2018 Gidon Ernst, Sean Sedwards, Zhenya Zhang, Ichiro Hasuo

We present an algorithm that quickly finds falsifying inputs for hybrid systems, i. e., inputs that steer the system towards violation of a given temporal logic requirement.

Scalable Verification of Markov Decision Processes

no code implementations14 Oct 2013 Axel Legay, Sean Sedwards, Louis-Marie Traonouez

Markov decision processes (MDP) are useful to model concurrent process optimisation problems, but verifying them with numerical methods is often intractable.
