Step-Level On-Policy Distillation: Interpolating Between On-Policy Distillation and Supervised Fine-Tuning

Changhui Sun, Lanbo Liu, Hang Lei +11

On-policy distillation (OPD) aligns a student model with a teacher's logit distribution on student-generated trajectories. This approach has achieved strong empirical gains and can…

First measurements of the branching fractions of $J / ψ$ and $ψ (3686) \to Σ^{0} Σ ˉ^{0} η$

BESIII Collaboration, M. Ablikim, M. N. Achasov +771

Based on $(10087 \pm 44) \times 1 0^{6}$ $J / ψ$ and $(2712 \pm 14) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector at the BEPCII collider, the hadronic decays $J/ψ\to…
