Researchers have developed a new multiclass learning framework designed for scenarios where obtaining exact labels is difficult or costly. This framework utilizes a weak supervision mechanism based on responses to queries about label subsets, rather than direct label assignments. The proposed method includes an unbiased estimator for target risk and introduces corrected risk estimators to combat overfitting, with theoretical analysis and experimental validation demonstrating its effectiveness.
