Researchers have introduced AdNGCL, a novel framework for graph contrastive learning designed to overcome the limitations of static negative sampling. This adaptive approach utilizes a hardness-aware scheduler (HANS) to dynamically manage the selection of negative samples based on their informativeness and computational cost. By adjusting sample selection based on contrastive loss trends and budget constraints, AdNGCL aims to improve the robustness and efficiency of representation learning. AI
