Greedy rollout
WebJun 16, 2024 · In Kool et al. , a Graph Attention Network encodes the d-dimensional representation of the node coordinates, and an attention-based decoder successively builds the solution; the model is trained end-to-end using the REINFORCE procedure with greedy rollout baseline. Webα (Policy LR): 0.01. β (Value LR): 0.1. Let’s first look at the results of using a simple baseline of whitening rewards: Our agent was able to achieve an average score of 234.4 over 50 ...
