Contrastive learning-based agent modeling for deep reinforcement learning

no code implementations30 Dec 2023 Wenhao Ma, Yu-Cheng Chang, Jie Yang, Yu-Kai Wang, Chin-Teng Lin

However, existing agent modeling approaches typically assume the availability of local observations from other agents (modeled agents) during training or a long observation trajectory for policy adaption.

Supervised Discriminative Sparse PCA with Adaptive Neighbors for Dimensionality Reduction

1 code implementation9 Jan 2020 Zhenhua Shi, Dongrui Wu, Jian Huang, Yu-Kai Wang, Chin-Teng Lin

Approaches that preserve only the local data structure, such as locality preserving projections, are usually unsupervised (and hence cannot use label information) and uses a fixed similarity graph.
