GeoMem-VLA: Internalizing 3D Scene Understanding into Temporal Memory for Vision-Language-Action Models

Geometric structure is essential for robotic manipulation and understanding the 3D world. Most VLA models rely on 2D representations of current observations, while geometry-aware approaches often require additional 3D information. However, geometry inferred independently from individual observations is often discarded...

VLA-Trace: Diagnosing Vision-Language-Action Models through Representation and Behavior Tracing

VLA-Trace is presented, a progressive diagnostic framework that analyzes VLA models through a unified evidence chain from representation dynamics to causal control attribution and behavioral manifestation to highlight future directions for representation-preserving adaptation, causal VLA circuits, and compositional sem...
