Researchers have introduced Coupled Calibration and Learning (CCL), a novel algorithm for distilling knowledge from large language models (LLMs) to smaller student models. CCL addresses the issue of transferring teacher bias and errors, especially under covariate shift where target-domain reward feedback is unavailable. The method iteratively calibrates the teacher model using source question feedback and then employs this calibrated teacher to train the student model on target questions. Theoretical analysis shows that CCL can converge to zero Kullback-Leibler divergence with an oracle student, effectively mitigating persistent teacher bias without requiring reward feedback on target data.
