Metalic: Meta-Learning In-Context with Protein Language Models

ICLR 2025poster

Predicting the biophysical and functional properties of proteins is essential for in silico protein design. Machine learning has emerged as a promising technique for such prediction tasks. However, the relative scarcity of in vitro annotations means that these models often have little, or no, specif…

Jumanji: a Diverse Suite of Scalable Reinforcement Learning Environments in JAX

ICLR 2024poster

Open-source reinforcement learning (RL) environments have played a crucial role in driving progress in the development of AI algorithms. In modern RL research, there is a need for simulated environments that are performant, scalable, and modular to enable their utilization in a wider range of potent…

Combinatorial Optimization with Policy Adaptation using Latent Space Search

NeurIPS 2023poster

Combinatorial Optimization underpins many real-world applications and yet, designing performant algorithms to solve these complex, typically NP-hard, problems remains a significant research challenge. Reinforcement Learning (RL) provides a versatile framework for designing heuristics across a broad…

Efficient Learning of Locomotion Skills through the Discovery of Diverse Environmental Trajectory Generator Priors

ICRA 2023poster

Data-driven learning based methods have recently been particularly successful at learning robust locomotion controllers for a variety of unstructured terrains. Prior work has shown that incorporating good locomotion priors in the form of trajectory generators (TGs) is effective at efficiently learni…

Winner Takes It All: Training Performant RL Populations for Combinatorial Optimization

NeurIPS 2023poster

Applying reinforcement learning (RL) to combinatorial optimization problems is attractive as it removes the need for expert knowledge or pre-solved instances. However, it is unrealistic to expect an agent to solve these (often NP-)hard problems in a single shot at inference due to their inherent com…
