Beyond Fixed Tasks: Unsupervised Environment Design for Task-Level Pairs
Introducing ATLAS, a method that generates joint curricula across both tasks and levels using unsupervised environment design. Rather than fixing tasks while designing environments, ATLAS automatically produces solvable yet challenging task-level pairs for policy training, substantially outperforming random sampling in complex scenarios.
Transformers Use Causal World Models in Maze-Solving Tasks
We identify World Models in transformers trained on maze-solving tasks, using Sparse Autoencoders and attention pattern analysis to examine their construction and demonstrate consistency between feature-based and circuit-based analyses.
Structured World Representations in Maze-Solving Transformers
Transformers trained to solve mazes form linear representations of maze structure, and acquire interpretable attention heads which facilitate path-following.
A Configurable Library for Generating and Manipulating Maze Datasets
A dataset to generate simple Maze-like environments for use with Transformers.
Sparse Relational Reasoning with Object-Centric Representations
Assessing the extent to which sparsity and structured (Obect-Centric) representations are beneficial for neural relational reasoning.
Nonlocal Thresholds for Improving the Spatial Resolution of Pixel Detectors
Investigating the potential use of charge sharing between neighboring pixels in HEP sensors to increase resolution and radiation hardness.
