DualOPSD: Closing the Feedback Loop in On-Policy Self-Distillation

On-policy self-distillation (OPSD) combines student generated trajectories with dense supervision from a privileged teacher of the same model. Its pointwise clipping protects the student from locally incompatible teacher directions, but the fixed teacher receives no feedback about the supervision the student rejects, w...

miR-6615-3p-androgen receptor axis modulates granulosa cell fate via the MDM2-p53-BCL2 pathway in hen Prehierarchical follicles

Results suggest that miR-6615-3p downregulates AR and is associated with reduced MDM2 expression, enhanced p53 activation, and decreased BCL2 expression, indicating that it may regulate cell fate and steroid hormone synthesis, at least in part, through the MDM2-p53-BCL2 signaling pathway.

DualOPSD: Adaptive Privileged Teachers for On-Policy Self-Distillation

DualOPSD, an asymmetric alternating framework that adapts both policies, reduces truncation across all three scales, and makes later supervision responsive to the learner and does not require another rollout.
