Researchers have developed a robust method for training lightweight agents in imperfect-information card games like Gin Rummy and Leduc Hold'em. By using a fixed, strong expert agent as a benchmark, they identified key training techniques that significantly improve agent performance. These include trust region updates, well-aimed rewards, a curriculum of increasingly difficult opponents, warm starting, and retaining the best model checkpoint. The study also found that certain architectural choices and training methods, such as learned state embeddings, imitation learning, and using large language models as opponents, were not beneficial or were too computationally expensive.
