Together, these contributions demonstrate how extended action representations and advanced policy models can advance the efficiency and versatility of RL.

020

EWRL @ewrl-org.bsky.social · 15/09/2025

Finally, we present diffusion policies as a more expressive policy class for maximum entropy RL, and highlight their advantageous properties for stability, flexibility, and scalability in complex domains.

130

EWRL @ewrl-org.bsky.social · 15/09/2025

Building on this foundation, we introduce a novel algorithm for skill discovery with MPs that leverages maximum entropy RL and mixture-of-expert models to autonomously acquire diverse, reusable skills.

120

EWRL @ewrl-org.bsky.social · 15/09/2025

However, standard MP-based approaches result in open-loop policies; to address this, we extend them with online replanning of MP trajectories and off-policy learning strategies that exploit single-time step information.

110

EWRL @ewrl-org.bsky.social · 15/09/2025

This parametrization allows black-box RL algorithms to adapt MP parameters to diverse contexts and initial states, providing a pathway toward versatile skill acquisition.

EWRL @ewrl-org.bsky.social · 15/09/2025

they encode trajectories with a concise set of parameters, naturally yielding smooth behaviors and enabling exploration in parameter space rather than in raw action space.

EWRL @ewrl-org.bsky.social · 15/09/2025

Abstract: Reinforcement learning (RL) with primitive actions often leads to inefficient exploration and brittle behaviors. Extended action representations, such as motion primitives (MPs), offer a more structured approach:

EWRL @ewrl-org.bsky.social · 10/09/2025

I will suggest a framework for answering these questions through the medium of potential-based shaping - in which 'liking' provides immediate, but preliminary and ultimately cancellable, information about the true, long-run worth of outcomes.

010

EWRL @ewrl-org.bsky.social · 10/09/2025

How could it be that we, or an agent, could `want' something that it does not `like', or `like' something that it would not be willing to exert any effort to acquire?

110

EWRL @ewrl-org.bsky.social · 10/09/2025

I will talk about an example of the complexity that has important psychological and neural resonance - namely the distinct concepts of 'liking' and 'wanting'. The former characterizes an immediate hedonic experience; and the latter the motivational force associated with that experience.

EWRL @ewrl-org.bsky.social · 10/09/2025

Abstract: As reinforcement learners, humans and other animals are excellent at improving their otherwise miserable lot in life. This is often described in terms of optimizing utility. However, understanding utility in a non-circular manner is surprisingly difficult.
