Deep-Unfolded Coordination
Summary
Deep Coordinator is a novel deep-unfolding framework that significantly enhances distributed optimization for multi-agent robotics problems by dynamically adjusting hyperparameters of the ADMM-DDP solver. This architecture unrolls a fixed number of ADMM-DDP iterations into a neural network, using learnable functions to map the optimizer state to subsequent hyperparameters at solve-time. It is the first deep-unfolding framework to adapt penalty parameters for a non-convex optimizer in real-time. The framework addresses the issue of degenerate solutions often seen with supervised training by proposing an unsupervised learning scheme. In simulations involving fleets of cars and quadrotors, Deep Coordinator achieved comparable trajectory quality while operating 6.18-9.44x faster than traditional solvers. Furthermore, it demonstrated robust scalability, maintaining its performance advantages on systems up to 8x larger than those used for training.
Key takeaway
For Machine Learning Engineers developing multi-agent robotics systems, Deep Coordinator offers a significant performance advantage. If you are struggling with slow distributed optimization or complex hyperparameter tuning for solvers like ADMM-DDP, consider integrating deep-unfolding frameworks. This approach can accelerate trajectory generation by 6.18-9.44x. It also scales effectively to larger fleets, reducing computational overhead and speeding up development cycles for complex robotic deployments.
