An Empirical Study of VLM Pipelines for Long-Document QA

Three of the strongest pipelines succeed on different questions, and an oracle that picks the best pipeline per question gains roughly thirteen points over the best single pipeline, though evidence-type routing recovers almost none of it.

S2Planner: Multi-Scale Semantic Planner for End-to-End Autonomous Driving

S2Planner is presented, a trajectory planner that combines three front-facing cameras with ego-motion history and the current driving command, and a coarse-to-fine decoder then uses trajectory self-attention and camera-projected cross-attention to refine candidate waypoints.

ReCalMatch:Reliability-Calibrated Semantic Guidance for Semi-Supervised Fine-Grained Recognition

ReCalMatch is a reliability-calibrated semantic framework for semi-supervised fine-grained recognition that down-weights pseudo-labels that are visually confident but semantically inconsistent, and consistently improves strong SSL baselines.

Investigating White Blood Cells as a Source of False-Positive Malaria Parasite Detection in African Blood-Smear Images

White blood cells (WBCs) present on every Giemsa-stained thick blood smear share visual properties with early-stage Plasmodium falciparum ring-form trophozoites: small size, round morphology, and intense purple staining. They are a plausible but untested source of false positives in parasite-only detectors. We trained...

Evidence-Driven Differential Diagnosis of Malignant Melanoma

An anatomic-site aware masked transformer is introduced, which effectively models the patient context by considering all lesions in a patient by considering all lesions in a patient, which can be variable in count, and their site of incidence.

QINA: Quantum-Inspired Nonlinear Adapters for Pretrained Vision Models

Adapting large pretrained vision models under limited data and frozen-backbone constraints remains a central challenge in transfer learning. While lightweight adapters and parameter-efficient fine-tuning methods are widely adopted, most rely on generic multilayer perceptrons or low-rank linear updates, offering limited...

CATCH: Counterfactual Anatomical Tissue Inpainting with Conditional Haar Diffusion

BraTS local synthesis replaces masked regions in T1-weighted brain MRI with plausible tumor-free tissue while preserving observed anatomy. We present CATCH, conditional 3D diffusion in an invertible Haar-wavelet domain. Its denoiser receives noisy target coefficients, voided-image coefficients, and a signed mask; tumor...

UNWIND: Any-Length Facial Video for Stress Detection without Temporal Windowing

UNWIND is introduced, a facial-video framework for stress detection that analyzes a complete recording as a single model input, eliminating the need for temporal windowing or external segmentation and showing that complete-recording inference can be performed within a single unified model.

GeoRefer-Bench: A Benchmark from Referring Pixels to Verifiable Geospatial Reasoning

Referring segmentation in overhead imagery is inherently relational: a query may ask for the buildings north of the road or the pond closest to a residential area, so the correct referent can contain one object, several objects, or none. Existing benchmarks mainly score mask overlap, which cannot verify whether a model...

CoSWA-YOLOv12: Scale-Invariant Tiny Object Detection and Segmentation of Malaria Parasites

Automated microscopy could widen access to malaria diagnosis in low-resource settings, but the deadliest species, P. falciparum, presents in its early ring stage as an object only a few tens of pixels wide. Such tiny targets are systematically under-detected: overlap-based label assignment starves them of positive samp...

AgriCountDINO: Parameter-Efficient Exemplar-Guided Counting and Localization in Agriculture

AgriCountDINO, a parameter-efficient exemplar-guided framework for joint counting and localization, is introduced, a parameter-efficient exemplar-guided framework for joint counting and localization that improves upon the best compared zero-shot method by 6.0\% without target-domain training or fine-tuning.

Frame-to-Panorama Localization and Context-Aware Sampling for Scene-Specific Ship Detection in a Smart Marina Testbed

Results demonstrate that highly redundant infrastructure video streams can be transformed into compact, spatially and contextually diverse training sets for scene-specific detector adaptation while substantially reducing annotation effort.

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.
