Reinforcement Learning with Action Sequence for Data-Efficient Robot Learning
Training reinforcement learning (RL) agents on robotic tasks typically requires a large
number of training samples. This is because training data often consists of noisy trajectories …

Action abstractions for amortized sampling
As trajectories sampled by policies used by reinforcement learning (RL) and generative flow
networks (GFlowNets) grow longer, credit assignment and exploration become more …

Predicting the Future with Simple World Models
World models can represent potentially high-dimensional pixel observations in compact
latent spaces, making it tractable to model the dynamics of the environment. However, the …

An inductive bias for slowly changing features in human reinforcement learning
Identifying goal-relevant features in novel environments is a central challenge for efficient
behaviour. We asked whether humans address this challenge by relying on prior knowledge …

Evaluating alignment between humans and neural network representations in image-based learning tasks
Humans represent scenes and objects in rich feature spaces, carrying information that
allows us to generalise about category memberships and abstract functions with few …

Meta-learning: Data, architecture, and both
We are encouraged by the many positive commentaries on our target article. In this
response, we recapitulate some of the points raised and identify synergies between them …

Simplifying Latent Dynamics with Softly State-Invariant World Models
To solve control problems via model-based reasoning or planning, an agent needs to know
how its actions affect the state of the world. The actions an agent has at its disposal often …

Two-shot learning of continuous interpolation using a conceptor-aided recurrent autoencoder
Generalizing from only two time series towards unseen intermediate patterns poses a
significant challenge in representation learning. In this paper, we introduce a novel …
