Light Cones For Vision: Simple Causal Priors For Visual Hierarchy

arXiv:2603.24753v1 Announce Type: new Abstract: Standard vision models treat objects as independent points in Euclidean space, unable to capture hierarchical structure like parts within wholes. We introduce Worldline Slot Attention, which models objects as persistent trajectories through spacetime worldlines, where…

Debugging Concept Bottleneck Models through Removal and Retraining

arXiv:2509.21385v2 Announce Type: replace-cross Abstract: Concept Bottleneck Models (CBMs) use a set of human-interpretable concepts to predict the final task label, enabling domain experts to not only validate the CBM’s predictions, but also intervene on incorrect concepts at test time.…

Consequentialist Objectives and Catastrophe

arXiv:2603.15017v2 Announce Type: replace-cross Abstract: Because human preferences are too complex to codify, AIs operate with misspecified objectives. Optimizing such objectives often produces undesirable outcomes; this phenomenon is known as reward hacking. Such outcomes are not necessarily catastrophic. Indeed, most…

The Geometry of Efficient Nonconvex Sampling

arXiv:2603.25622v1 Announce Type: cross Abstract: We present an efficient algorithm for uniformly sampling from an arbitrary compact body $mathcal{X} subset mathbb{R}^n$ from a warm start under isoperimetry and a natural volume growth condition. Our result provides a substantial common generalization…

Flow matching on homogeneous spaces

arXiv:2603.24829v1 Announce Type: new Abstract: We propose a general framework to extend Flow Matching to homogeneous spaces, i.e. quotients of Lie groups. Our approach reformulates the problem as a flow matching task on the underlying Lie group by lifting the…
