ALINC: Active Learning for Inductive Node Classification via Graph Sampling
Researchers have introduced ALINC, a new active learning framework designed for inductive node classification tasks involving numerous independent graphs. Unlike traditional methods that select individual nodes, ALINC focuses on sampling entire graphs, which is crucial in domains where node annotation requires a full-graph analysis. The framework bridges a methodological gap by adapting node-level utility measures to graph-level selection criteria using various aggregation mechanisms. Experiments show that CoreSet, TypiClust, and BADGE are top graph sampling strategies, and the choice of aggregation method significantly impacts performance and cost. AI
