Backpropagating Through Simulation: Analytic Policy Gradients for Sample and Learning Efficient Differentiable Continuous Control

Researchers propose Analytic Policy Gradients (APG), a method that computes exact policy gradients through backpropagation in differentiable simulators, contrasting with model-free approaches like PPO that rely on sampled rewards. Testing across four continuous control tasks shows APG achieves superior sample efficiency, with a segmented backpropagation scheme that mitigates gradient degradation on long-horizon problems.

RigidFormer: Learning Rigid Dynamics using Transformers

RigidFormer is a Transformer-based neural network that learns rigid-body dynamics simulation from mesh-free point cloud inputs, addressing computational bottlenecks in existing mesh-dependent methods. The model uses object-level reasoning with anchor-based attention mechanisms and enforces physical rigidity constraints through differentiable Kabsch alignment, demonstrating superior performance and generalization across benchmarks.
