Large Scale Distributed Collaborative Unlabeled Motion Planning with Graph Policy Gradients

no code implementations11 Feb 2021 Arbaaz Khan, Vijay Kumar, Alejandro Ribeiro

We are able to demonstrate the scalability of our methods for a large number of robots by employing a graph neural network (GNN) to parameterize policies for the robots.

Sufficiently Accurate Model Learning

no code implementations19 Feb 2019 Clark Zhang, Arbaaz Khan, Santiago Paternain, Alejandro Ribeiro

In this paper, we investigate a method to regularize model learning techniques to provide better error characteristics for traditional control and planning algorithms.

Scalable Centralized Deep Multi-Agent Reinforcement Learning via Policy Gradients

no code implementations22 May 2018 Arbaaz Khan, Clark Zhang, Daniel D. Lee, Vijay Kumar, Alejandro Ribeiro

When the number of agents increases, the dimensionality of the input and control spaces increase as well, and these methods do not scale well.

Memory Augmented Control Networks

no code implementations ICLR 2018 Arbaaz Khan, Clark Zhang, Nikolay Atanasov, Konstantinos Karydis, Vijay Kumar, Daniel D. Lee

The third part uses a network controller that learns to store those specific instances of past information that are necessary for planning.

Neural Network Memory Architectures for Autonomous Robot Navigation

no code implementations23 May 2017 Steven W. Chen, Nikolay Atanasov, Arbaaz Khan, Konstantinos Karydis, Daniel D. Lee, Vijay Kumar

This work is a first thorough study of memory structures for deep-neural-network-based robot navigation, and offers novel tools to train such networks from supervision and quantify their ability to generalize to unseen scenarios.
