Researchers introduce the Mimic Score, a geometry-based metric for evaluating data quality in large datasets by measuring gradient alignment with pre-trained models. The proposed Grad-Mimic framework enables efficient data selection, reducing training steps for CLIP models by 20.7% and filtering datasets without expensive computations or validation sets.
Researchers introduce CloudWeb, an adversarial attack that manipulates remote sensing images with realistic cloud and haze patterns to hijack vision-language retrieval systems in multimodal RAG pipelines. The attack achieves significant success rates—increasing weather-related evidence injection from 0.71% to 43.29% on benchmark tests—demonstrating that input-space threats to retrieval stages remain largely undefended in production systems.
Researchers introduce Open-SAT, a training-free algorithm that uses Large Language Models to refine query embeddings for satellite image retrieval tasks. The method improves upon existing vision-language models by leveraging LLM-guided contextual refinement at inference time, achieving up to 16% F1 score improvement on open-vocabulary satellite imagery tasks without requiring additional training.
Researchers introduce CLIP-Inspector, a backdoor detection method for prompt-tuned CLIP models that reconstructs hidden triggers using out-of-distribution images to identify if a model has been maliciously compromised. The technique achieves 94% detection accuracy and enables post-hoc model repair, addressing critical security vulnerabilities in outsourced machine learning services.
