A multi-center analysis of deep learning methods for video polyp detection and segmentation

This multi-center study evaluates deep learning methods for real-time video polyp detection and segmentation, demonstrating that integrating sequence data and temporal information significantly enhances diagnostic precision by addressing the challenges of variable polyp appearance and reducing missed detection rates in colonoscopy.

CubeComposer: Spatio-Temporal Autoregressive 4K 360° Video Generation from Perspective Video

CubeComposer is a novel spatio-temporal autoregressive diffusion model that overcomes the computational limitations of existing methods to natively generate high-quality, seam-free 4K-resolution 360° videos from perspective inputs by decomposing them into cubemap representations and employing efficient context management and continuity-aware techniques.

RANGER: Sparsely-Gated Mixture-of-Experts with Adaptive Retrieval Re-ranking for Pathology Report Generation

The paper proposes RANGER, a novel framework for pathology report generation that combines a sparsely-gated Mixture-of-Experts decoder with an adaptive retrieval re-ranking module to overcome limitations in existing transformer-based approaches by enabling dynamic expert specialization and reducing noise from external knowledge retrieval.
