From Knowing to Abstaining: Bridging the Representation-Action Gap in Vision-Language Models

Rep2Act, a representation-to-action alignment method that translates latent answerability awareness into explicit abstention decisions, is introduced, a representation-to-action alignment method that translates latent answerability awareness into explicit abstention decisions.

Tokenizer-Generator Coupling in Medical Image Generation

Latent medical image generators usually treat the tokenizer as fixed preprocessing. We test whether this separation holds in a controlled ChestMNIST study at $64\times64$ that crosses discrete tokenizers, generator families, and sampler settings under a shared latent grid, with continuous-latent reference cells. The ra...

Beyond Flat Labels: Level-Restricted Contrastive Learning for Hierarchical Fine-Grained Vision Classification

This work proposes to restrict contrastive comparisons to categories within the same taxonomic level, and adopts a group-balanced design, ensuring each taxonomic level receives adequate optimization and improves both hierarchical consistency and classification accuracy from coarse to fine granularity.

Driving Video Retrieval for Complex Queries with Structured Grounding

STRIVE-D, a data-calibrated retrieval framework for driving videos, uses weakly labeled in-domain videos to estimate when a query rule is reliable, adapt rules that mismatch observed data, and fuse calibrated rule scores with vision-language and keyword-based retrieval signals.

Diagnosing Visual Ignorance in Vision-Language Models

Across three VLMs and twelve benchmarks, this work tracks the answer-relevant information decodable at each decoder layer and measures when it becomes coupled to the final output, and distinguishes the availability of visual information from its influence on prediction.

FIS-DiT: Breaking the Few-Step Video Inference Barrier via Training-Free Frame Interleaved Sparsity

While the overall inference latency of Video Diffusion Transformers (DiTs) can be substantially reduced through model distillation, per-step inference latency remains a critical bottleneck. Existing acceleration paradigms primarily exploit redundancy across the denoising trajectory; however, we identify a limitation wh...

Probabilistic Object Detection with Conformal Prediction

Conformal Prediction (CP) is a distribution-free method for constructing prediction sets with marginal finite-sample coverage guarantees, making it a suitable framework for reliable uncertainty quantification in safety-critical object detection. However, object detection introduces structured multi-output predictions,...

TrajGANR: Trajectory-Centric Urban Multimodal Learning via Geospatially Aligned Neural Representations

Many urban prediction tasks depend not only on the static attributes of a location, such as the visual appearance of its built environment, but also on its dynamic function: how people navigate and use it over time. Predicting congestion, travel demand, or road safety risks, for instance, requires mobility information...

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.
