Abstract

fetched live from OpenAlex

The ability to estimate the motion of objects is crucial for robotic agents to act and interact in their environments. This is particularly challenging for non-rigid objects, as they exhibit complex dynamics with large degrees of freedom. This work presents a methodology to learn deformation models of 3D elastic objects based on graph networks. Our approach exploits physical reasoning by introducing soft constraints into the loss function during training. We evaluate the proposed method in a simulation framework developed for robotic manipulation tasks. Results show that such a physics-informed model is able to predict more accurate object motions with less data than a purely data-driven based model.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
