Constructing an Optimal Behavior Basis for the Option Keyboard

arXiv:2505.00787v2 Announce Type: replace-cross Abstract: Multi-task reinforcement learning aims to quickly identify solutions for new tasks with minimal or no additional interaction with the environment. Generalized Policy Improvement (GPI) addresses this by combining a set of base policies to produce…

One-Shot Multi-Label Causal Discovery in High-Dimensional Event Sequences

arXiv:2509.23213v2 Announce Type: replace-cross Abstract: Understanding causality in event sequences with thousands of sparse event types is critical in domains such as healthcare, cybersecurity, or vehicle diagnostics, yet current methods fail to scale. We present OSCAR, a one-shot causal autoregressive…

CTRL-ALT-DECEIT: Sabotage Evaluations for Automated AI R&D

arXiv:2511.09904v1 Announce Type: new Abstract: AI systems are increasingly able to autonomously conduct realistic software engineering tasks, and may soon be deployed to automate machine learning (ML) R&D itself. Frontier AI systems may be deployed in safety-critical settings, including to…

MVU-Eval: Towards Multi-Video Understanding Evaluation for Multimodal LLMs

arXiv:2511.07250v2 Announce Type: replace-cross Abstract: The advent of Multimodal Large Language Models (MLLMs) has expanded AI capabilities to visual modalities, yet existing evaluation benchmarks remain limited to single-video understanding, overlooking the critical need for multi-video understanding in real-world scenarios (e.g.,…

RoboBenchMart: Benchmarking Robots in Retail Environment

arXiv:2511.10276v1 Announce Type: cross Abstract: Most existing robotic manipulation benchmarks focus on simplified tabletop scenarios, typically involving a stationary robotic arm interacting with various objects on a flat surface. To address this limitation, we introduce RoboBenchMart, a more challenging and…
