ITR: Iterative Transductive Refinement with a Graph-Reliability Gate for Zero-Shot Agricultural CLIP Classification
ITR (Iterative Transductive Refinement), a parameter-free, training-free method that refines the frozen-CLIP zero-shot posterior over a whole unlabelled test batch by iterating, for two rounds, three established operators: k-nearest-neighbour (k-NN) label propagation on CLIP image features, lightweight LLM-free agricul...
