MO2: Model-Based Offline Options

no code implementations5 Sep 2022 Sasha Salter, Markus Wulfmeier, Dhruva Tirumala, Nicolas Heess, Martin Riedmiller, Raia Hadsell, Dushyant Rao

The ability to discover useful behaviours from past experience and transfer them to new tasks is considered a core component of natural embodied intelligence.

Attention-Privileged Reinforcement Learning

no code implementations19 Nov 2019 Sasha Salter, Dushyant Rao, Markus Wulfmeier, Raia Hadsell, Ingmar Posner

Image-based Reinforcement Learning is known to suffer from poor sample efficiency and generalisation to unseen visuals such as distractors (task-independent aspects of the observation space).

Imagine That! Leveraging Emergent Affordances for 3D Tool Synthesis

no code implementations30 Sep 2019 Yizhe Wu, Sudhanshu Kasewa, Oliver Groth, Sasha Salter, Li Sun, Oiwi Parker Jones, Ingmar Posner

In this paper we explore the richness of information captured by the latent space of a vision-based generative model.

Attention Privileged Reinforcement Learning for Domain Transfer

no code implementations25 Sep 2019 Sasha Salter, Dushyant Rao, Markus Wulfmeier, Raia Hadsell, Ingmar Posner

Applying reinforcement learning (RL) to physical systems presents notable challenges, given requirements regarding sample efficiency, safety, and physical constraints compared to simulated environments.

TACO: Learning Task Decomposition via Temporal Alignment for Control

1 code implementation ICML 2018 Kyriacos Shiarlis, Markus Wulfmeier, Sasha Salter, Shimon Whiteson, Ingmar Posner

Many advanced Learning from Demonstration (LfD) methods consider the decomposition of complex, real-world tasks into simpler sub-tasks.
