LaCoGSEA: Unsupervised deep learning for pathway analysis via latent correlation

arXiv
Motivation: Pathway enrichment analysis is widely used to interpret gene expression data. Standard approaches, such as GSEA, rely on predefined phenotypic labels and pairwise comparisons, which limits their applicability in unsupervised settings. Exi... read more 

Geometry-Free Conditional Diffusion Modeling for Solving the Inverse Electrocardiography Problem

arXiv
This paper proposes a data-driven model for solving the inverse problem of electrocardiography, the mathematical problem that forms the basis of electrocardiographic imaging (ECGI). We present a conditional diffusion framework that learns a probabili... read more 

Issues regarding the Indexing of Publication Types and Study Designs

arXiv
Objectives. Major research and implementation efforts have been devoted to indexing articles according to the major topics discussed, but much less effort to indexing their publication types and study designs (collectively, PTs). In this Perspective,... read more 

Scale-Aware Self-Supervised Learning for Segmentation of Small and Sparse Structures

arXiv
Self-supervised learning (SSL) has emerged as a powerful strategy for representation learning under limited annotation regimes, yet its effectiveness remains highly sensitive to many factors, especially the nature of the target task. In segmentation,... read more 

Adaptive Domain Shift in Diffusion Models for Cross-Modality Image Translation

arXiv
Cross-modal image translation remains brittle and inefficient. Standard diffusion approaches often rely on a single, global linear transfer between domains. We find that this shortcut forces the sampler to traverse off-manifold, high-cost regions, in... read more 

CONQUER: Context-Aware Representation with Query Enhancement for Text-Based Person Search

arXiv
Text-Based Person Search (TBPS) aims to retrieve pedestrian images from large galleries using natural language descriptions. This task, essential for public safety applications, is hindered by cross-modal discrepancies and ambiguous user queries. We ... read more 

Splat-Portrait: Generalizing Talking Heads with Gaussian Splatting

arXiv
Talking Head Generation aims at synthesizing natural-looking talking videos from speech and a single portrait image. Previous 3D talking head generation methods have relied on domain-specific heuristics such as warping-based facial motion representat... read more 

TwinPurify: Purifying gene expression data to reveal tumor-intrinsic transcriptional programs via self-supervised learning

arXiv
Advances in single-cell and spatial transcriptomic technologies have transformed tumor ecosystem profiling at cellular resolution. However, large scale studies on patient cohorts continue to rely on bulk transcriptomic data, where variation in tumor ... read more 

Learning temporal embeddings from electronic health records of chronic kidney disease patients

arXiv
We investigate whether temporal embedding models trained on longitudinal electronic health records can learn clinically meaningful representations without compromising predictive performance, and how architectural choices affect embedding quality. Mo... read more 

Health-SCORE: Towards Scalable Rubrics for Improving Health-LLMs

arXiv
Rubrics are essential for evaluating open-ended LLM responses, especially in safety-critical domains such as healthcare. However, creating high-quality and domain-specific rubrics typically requires significant human expertise time and development co... read more
