Decentralized Gaussian Processess for Multi-Robot Systems

Demonstration code of decentralized methods for Gaussian processes [1]. For further details check the paper here. A 3-minute presentation of the paper can be found here.

Contents

The code implements:

• Decentralized Nested Pointwise Aggregation of Experts (DEC-NPAE)
• Distributed Nested Pointwise Aggregation of Experts (DIST-NPAE)

The source code of the factorized training and the centralized NPAE [2] can be found in the GRBCM [3] GitHub repository.

Execution

Install the gpml toolbox.

Execute:
