Wasserstein Discriminant Dictionary Learning for Graph Representation

2024 · IEEE Transactions on Pattern Analysis and Machine Intelligence

Mining discriminative graph topological information plays an important role in promoting graph representation ability. However, it suffers from two main issues: (1) the difficulty/complexity of computing global inter-class/intra-class scatters, commonly related to mean and covariance …

TVDO: Tchebycheff Value-Decomposition Optimization for Multiagent Reinforcement Learning

2024 · IEEE Transactions on Neural Networks and Learning Systems

In cooperative multiagent reinforcement learning (MARL), centralized training with decentralized execution (CTDE) has recently attracted more attention due to the physical demand. However, the most dilemma therein is the inconsistency between jointly-trained policies and individually …
