PAMD: Structured Adaptive Distances for Bisimulation Representations in Visual Reinforcement Learning
Daegyeong Roh, Juho Bae, Han-Lim Choi
Many visual reinforcement learning (RL) algorithms learn representations by matching latent distances to a behavioral distance induced by reward and transition similarity. In pract…

Fixed-Time State Transfer via Pontryagin Extremals
Juho Bae, Han-Lim Choi
This paper concerns the problem of fixed-time transition between two states of nonlinear systems (i.e., the point-to-point steering problem). We propose a formulation applicable to…

Learning Safety-Compatible Observers for Unknown Systems
Juho Bae, Daegyeong Roh, Han-Lim Choi
This paper presents a data-driven approach for jointly learning a robust full-state observer and its robustness certificate for systems with unknown dynamics. Leveraging incrementa…
