MIDR: Enrichment-Augmented Indexing for Multimodal Document Retrieval

MIDR (Multimodal Indexing for Document Retrieval), a training-free framework for enrichment-augmented indexing that shifts multimodal reasoning to index time, establishes index-time multimodal reasoning as a compelling accuracy-deployment alternative to serving-time visual late interaction.

GazeRefine: Expert Gaze as a Test-Time Prompt for Training-Free Medical Image Segmentation

The results show strong performance on colonoscopy images and competitive performance on prostate MRI, supporting gaze-guided prototype refinement as a promising approach for segmentation-label-efficient, human-in-the-loop medical image segmentation.

HiLRP: Toward One Trustworthy Explanation for Vision Transformer: Conservation-Valid Attribution via Attention Primitives

HiLRP alone preserves conservation across windowed, spatial-reduction, multi-axis, and linear-attention models, where naive extensions can produce zero or inflated relevance, and localizes attribution failures in class activation mapping.

TimeSteer: Inference-Time Speech Scheduling in Joint Audio-Visual Diffusion Models

A training-free framework that localizes each utterance's source span through Source Span Localization and transfers the associated audio-visual latent content from the source interval to the specified target interval through Region-Aware Latent Remapping is proposed.

StainPresetNet: Stain Preset Network for Fast Multi-to-Multi Stain Normalization

This work proposes StainPresetNet - a novel framework that combines structural preservation with dataset-level color mapping while maintaining computational efficiency, and implements pixel-wise normalization guided by preset reference images, enabling multi-directional adaptability without retraining.

ViTAMINS: An Empirical Study of Training Self-Supervised Vision Transformers with Synthetic Hard Negatives

This work introduces ViTAMINS, a method that integrates synthetic hard negatives into unsupervised vision transformer pretraining to improve representation quality and motivate reconsidering contrastive learning as a simpler yet powerful alternative to dominant generative and self-distillation approaches.

SinkPruner: Sink-Free Visual Token Pruning for Multimodal Large Language Models

SinkPruner is proposed, a training-free visual token pruning framework for efficient MLLM inference that follows a coarse-to-fine design with two key modules: a visual sanitizer that filters high-norm redundancies and alleviates attention sink and attention dispersion, and a text-guided pruner that further retains toke...

Semi-Supervised Virtual Staining via Morphology Preservation and Histopathological Realism Constraints

A stable semi-supervised virtual staining framework that jointly exploits both limited paired data and abundant unpaired source images is proposed, which suppress structural and appearance drift, stabilize semi-supervised stain translation, and promote the preservation of diagnostically relevant information.

From Terminology to Diagrams: Visual-Instruction Generation for Scientific Diagram Understanding

A framework for generating large-scale diagram-grounded instruction data by leveraging terminology derived from scientific curricula is introduced, and augmenting existing models such as LLaVA OneVision with SciGram establishes new state-of-the-art performance on diagram question answering.

Beyond the Image Plane: World-Grounded Queries for Multi-Object Tracking

This work introduces PLANET, an end-to-end multi-object tracker designed to move beyond the image plane, and lifts existing 2D tracking datasets into 3D by embedding reconstructed 3D scene geometry into the features and positional encodings used during query formation.

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.
