Adapting simulated character interactions to different morphologies and interaction scenarios

Abstract

Some implementations relate to methods, systems, and computer-readable media for adapting simulated character interactions to different morphologies and interaction scenarios. The system accesses a graph representing a control policy for a simulated character's movements in a virtual environment. This graph undergoes encoding and processing through a graph neural network to generate latent embeddings for the graph. A fixed-length latent vector is determined from the latent embeddings. This vector is input to a feedforward neural network, generating control signals for the character's actions. Through a reinforcement learning loop, the character's motions are continuously refined by iteratively adjusting the graph based on evaluating the actions of the simulated character via a reward function, adapting the control policy to different character morphologies and/or interaction scenarios.
