SD-LoRA: Training-Time Structural Distillation into LoRA for Few-Shot Vision-Language Adaptation

SD‑LoRA introduces a training‑time structural distillation framework that embeds token‑level graph reasoning into a lightweight LoRA‑adapted CLIP model for few‑shot vision‑language adaptation. During training, a heterogeneous graph teacher captures patch‑patch, global‑local, and visual‑text relations over high‑resolution ViT tokens, and its structural bias is transferred to the CLIP‑LoRA backbone via implicit distillation and Prototype Predictive Alignment. At inference, the graph teacher is discarded, requiring only a single CLIP‑LoRA forward pass and a cache‑based classifier, yielding significant accuracy gains across 11 few‑shot benchmarks without extra computation.

MLLMCLIP: Feature-Level Distillation of MLLM for Robust Vision-Language Representations

MLLMCLIP introduces a heterogeneous distillation framework that transfers multimodal knowledge from a generative Multimodal Large Language Model (MLLM) teacher directly into a discriminative CLIP student, eliminating the need for synthetic hard negatives. The method uses an attention-based per-layer token selection and a CKA-based distillation loss to bridge architectural differences between the two models. As a result, MLLMCLIP achieves state‑of‑the‑art compositional accuracy and improves zero‑shot classification and image‑text retrieval performance.

Visual Distribution Anchoring for Efficient Prompt Tuning

arXiv:2607. 28967v1 Announce Type: cross Abstract: Prompt tuning adapts vision--language models with few trainable parameters, but existing approaches trade off efficiency and adaptation: static textual prompts can overfit source classes, image-conditioned prompts add per-instance computation, and multimodal tuning modifies the visual branch.

UINO-FSS: Unifying Representation Learning and Few-shot Segmentation via Hierarchical Distillation and Mamba-HyperCorrelation

The paper introduces UINO-FSS, a unified framework for few-shot semantic segmentation that merges knowledge from DINOv2 and SAM into a single-encoder architecture. It employs coarse-to-fine multimodal distillation, a bottleneck adapter for embedding alignment, a meta-visual prompt generator, and a mask decoder, enhanced by Mamba-based 4D correlation mining. Experiments on PASCAL-5i and COCO-20i demonstrate state‑of‑the‑art performance in 1‑shot settings, achieving 80.6% mIoU on PASCAL-5i and 64.5% on COCO-20i.

One Model, Many Graphs: Learning over Attributed Graphs across Heterogeneous Modalities with Vision-Language Models

arXiv:2607. 19128v1 Announce Type: new Abstract: Vision-language models (VLMs) provide a unified representation space for textual and visual information, yet their potential as general-purpose backbones for graph-structured data remains largely unexplored.

On the Few-Shot Adaptation of Vision-Language Models: A Few Gradient Signs Are All You Need

The paper investigates few-shot adaptation of vision-language models, noting that gradient magnitudes are poorly calibrated while the signs of a few top-magnitude gradients remain informative. It proposes two state‑free optimizers, SignSparseSGD and DynSignSparseSGD, which use gradient magnitudes only to select update locations and fixed‑magnitude signs to determine update directions. Across 11 datasets, three CLIP backbones, and five shot levels, these methods match or surpass parameter‑efficient and optimization‑based baselines, show reduced sensitivity to long training schedules, and require no task‑specific modules or optimizer state beyond a single shared configuration.
