Recovering General Capabilities via Uncertainty-Calibrated Multi-Teacher On-Policy Distillation

The proposed Uncertainty-Calibrated MOPD (UCMOPD), which addresses limitations of standard MOPD through two complementary mechanisms, improves the general-capability average over standard MOPD by $4.48\% and $7.86\% while maintaining vertical-domain performance.

Counteraction-Aware Multi-Teacher On-Policy Distillation for General Capability Recovery with Domain Preservation

Counteraction-Aware Multi-Teacher On-Policy Distillation is proposed, which addresses issues with decoupled alternating training and gap-based sample selection and outperforms all baselines in general capability recovery while maintaining domain-specific behavior.

Manifold-Constrained Noise Optimization for Diverse Diffusion Sampling

MoNO is proposed, a training-free method that performs Manifold-constrained Noise Optimization on a low-dimensional, quality-stabilizing noise manifold that combines Riemannian updates on an affine low-frequency sphere to preserve prior likelihood and fix unstable high-frequency components by construction.
