Graph Based Active Learning
Graph-based active learning aims to efficiently train machine learning models on graph-structured data by strategically selecting a minimal subset of nodes for labeling. Current research focuses on developing novel acquisition functions that consider both node informativeness (e.g., uncertainty, diversity) and representativeness within the graph structure, often incorporating graph neural networks (GNNs) and graph signal processing techniques. This approach is crucial for applications where labeling data is expensive or time-consuming, improving the efficiency and effectiveness of various tasks, including node classification, entity cluster repair, and even antimicrobial peptide design. The resulting label-efficient models offer significant advantages across diverse domains.
