TokenFlow: Latent Token Rectified Flow Matching for 3D Point Cloud Generation

3D point clouds generation requires capturing both part-level layout and surface detail while preserving permutation equivariance. Existing latent generative models often encode an entire shape into a single vector, which limits their ability to retain part-level structure. We propose TokenFlow, a hierarchical flow mat...

Not All Errors Matter: Decision-Relevant Prediction Error Predicts Planning Quality

Decision-Relevant Prediction Error (DRPE), which measures prediction error on the state dimensions that affect decisions, is introduced and sufficient conditions under which DRPE correctly ranks models and total prediction error cannot are formalized.
