Adaptive Dual-Teacher Distillation with Subnetwork Rectification for Bridging Semantic Gaps in Black-Box Domain Adaptation

The paper introduces Adaptive Dual-Teacher Distillation with Subnetwork Rectification (DDSR), a method for black-box domain adaptation that fuses predictions from a black-box source model and a vision‑language model to generate reliable pseudo‑labels for the target domain. DDSR uses adaptive prediction fusion, subnetwork regularization to prevent overfitting, iterative refinement of pseudo‑labels and prompts, and class‑wise prototypes for self‑training. Experiments on several benchmark datasets show that DDSR outperforms existing state‑of‑the‑art approaches, even those that have access to source data or source model parameters.

Adaptive Mutual Distillation for Balanced Multi-Task Post-Training of Large Language Models

The paper introduces Adaptive Mutual Distillation (AMD), a post‑training framework that jointly trains two large language models using different task‑balancing strategies. AMD evaluates and selects distillation weight adjustments via short training probes and task‑wise validation, leading to models that outperform supervised fine‑tuning baselines on six benchmarks across three backbones. Merging the two AMD models further improves performance, surpassing multi‑task fine‑tuning by an average of 2.91 points.
