ViSAR: Training-Free Adaptive-$k$ Retrieval for Visual Document Question Answering

ViSAR (Visual Semantic Activation Retrieval), a training-free adaptive-$k$ retrieval method for late-interaction visual document retrieval, is introduced and it is shown that the similarity matrix structure correlates with answer accuracy, suggesting future directions for retrieval quality-aware document understanding.

RouteGraph-Mona: Confusion-Aware Routing Fine-Tuning for Mineral Image Classification

Mineral image classification is important for geological exploration and resource development, but it remains challenging due to substantial intra-class variations in appearance and high inter-class visual similarity. Multi-cognitive Visual Adapter (Mona) is a vision-oriented parameter-efficient adapter that adapts pre...

Signal or Noise? Auditing Rotation-Induced Saliency Drift in Medical and Aerial Imaging

Post-hoc saliency maps such as Grad-CAM are increasingly used to audit why a deployed vision model made a decision, yet the heatmap drifts when the input is rotated, even when the prediction is unchanged. In domains with no canonical orientation, such as histopathology and aerial imagery, this undermines using saliency...

Disease Burden over Skin Tone: Decomposing the Dermatology-AI Generalization Gap

Dermatology artificial intelligence (AI) models are predominantly trained on light-skinned, cancer-focused image collections, yet they are increasingly proposed for deployment in resource-constrained settings where patients differ from training populations along two confounded axes: skin tone and disease distribution....

Federated LoRA Adaptation of BiomedCLIP Across Four International Chest X-Ray Cohorts

Federated LoRA adaptation improves shared-class AUC on all four cohorts over the unadapted BiomedCLIP backbone over the unadapted BiomedCLIP backbone, showing that the gains come from federated adaptation rather than from the pretrained model's zero-shot ability.

InstEditSeg: Instruction-Driven Image Editing for Polyp and Skin Lesion Segmentation

InstEditSeg is proposed, a unified generative framework that reformulates medical segmentation as an instruction-driven image editing problem, and achieves accuracy competitive with strong discriminative baselines, and demonstrates concrete advantages of the generative formulation.

InsightSeg: Reusing Correction Insights for Guideline-Consistent Segmentation

InsightSeg is introduced, an episodic memory mechanism that converts successful correction episodes into reusable, visually grounded insights that improves both first-pass and final guideline-consistent segmentation performance while requiring fewer refinement steps, demonstrating that multi-agent refinement can become...

What AI gets wrong and what failure teaches us

Jennifer Neville did not want to go into computer science—but that’s exactly where she landed. Neville discusses the starts and stops that led to her professional sweet spot and her work identifying “surprising failures” making it hard for AI to handle complexity.  The post What AI gets wrong and what failure teaches us appeared first on Microsoft Research.
