Summary

A model-driven approach is proposed for developing families of Reinforcement Learning (RL) training environments, addressing the labor-intensive and error-prone manual process typically required for creating multiple, slightly varied environments. These environment families are crucial for training RL agents in realistic scenarios and for curriculum learning paradigms. The approach utilizes a hybrid genetic algorithm, combining population-based global search with heuristic local search, to generate diverse environment families. Mutations and constraints within this system are expressed as model transformations, which are then operationalized into the search process by a state-of-the-art model transformation engine. The soundness of this method is demonstrated through its application in a wildfire mitigation scenario and for facilitating curriculum learning, with a prototype tool developed to support the process.

Key takeaway

For Machine Learning Engineers developing complex Reinforcement Learning agents, manually creating diverse training environments is inefficient. You should consider adopting a model-driven approach to automate the generation of environment families, especially for curriculum learning or scenarios like wildfire mitigation. This method, leveraging hybrid genetic algorithms and model transformations, can significantly reduce development time and errors, allowing you to scale your agent training more effectively.
