Specializing Inter-Agent Communication in Heterogeneous Multi-Agent Reinforcement Learning using Agent Class Information

no code implementations14 Dec 2020 Douglas De Rizzo Meneghetti, Reinaldo Augusto da Costa Bianchi

Inspired by recent advances in agent communication with graph neural networks, this work proposes the representation of multi-agent communication capabilities as a directed labeled heterogeneous agent graph, in which node labels denote agent classes and edge labels, the communication type between two classes of agents.

Detecting soccer balls with reduced neural networks: a comparison of multiple architectures under constrained hardware scenarios

1 code implementation28 Sep 2020 Douglas De Rizzo Meneghetti, Thiago Pedro Donadon Homem, Jonas Henrique Renolfi de Oliveira, Isaac Jesus da Silva, Danilo Hernani Perico, Reinaldo Augusto da Costa Bianchi

We train multiple open implementations of MobileNetV2 and MobileNetV3 models with different underlying architectures, as well as YOLOv3, TinyYOLOv3, YOLOv4 and TinyYOLOv4 in an annotated image data set captured using a mobile robot.
