SI-Diff: A Framework for Learning Search and High-Precision Insertion with a Force-Domain Diffusion Policy

The paper frames the work as diffusion policyModern Robot LearningDiffusion policyA robot policy that generates actions using diffusion-model techniques.. Start here because it defines what success means and which assumptions the rest of the method inherits.
