Voxelized 3D Gaussian Representation for Dense Visual SLAM on Embedded Vision System

A voxelized compact 3D Gaussian representation for SLAM system that reduces the number and the parameter size of Gaussian ellipsoids is proposed, and a novel residual codebook-based quantization method is proposed to further compress 3D Gaussian attributes.

DiffSAC: Diffusion-guided Sampling for Consensus-based Robust Estimation

A novel Diffusion-guided Sampling for Consensus-based Robust Estimation (DiffSAC) framework that refines the confidence for each data point, indicating whether it belongs to a good minimum set, rather than ranking the data points as in previous work, significantly reduces the need to process numerous bad sets.

Teach and Grow: An Agent-Centered Architecture for General Robot Learning

Vision-language-action (VLA) and world-action models typically absorb unfamiliar manipulation tasks through additional robot data collection and policy optimization. This recurring retraining burden slows the acquisition of new behavior. We present Teach-and-Grow Learning (TGL), a training-free architecture that turns...
