Graph Level Task
Graph-level tasks involve applying machine learning models, particularly Graph Neural Networks (GNNs) and Large Language Models (LLMs), to analyze and reason about entire graph structures, aiming to predict properties or classifications of the graph as a whole. Current research focuses on improving the efficiency and accuracy of these models, addressing challenges like over-smoothing in GNNs and the "lost-in-distance" problem in LLMs when processing complex graph information, often through techniques like graph sparsification, instruction tuning, and novel prompting methods. This field is significant because effective graph-level analysis is crucial for diverse applications across numerous domains, including social network analysis, drug discovery, and recommendation systems, enabling more sophisticated insights from complex relational data.
