Transformer-augmented reinforcement learning in the Unity Food Collector environment
Can a transformer beat the MLP inside PPO and SAC? A three-way study placing the transformer on the actor, the critic, or both, with a CoordConv-ResNet encoder, the failure modes that shaped it, and held-out results across five agents.
- Unity ML-Agents Food Collector (5×40×40 grid sensor, hybrid action space)
