REVEAL++: Differentiable Phenotypic Grouping for Vision-Language Retinal Modeling of Alzheimer's Disease Risk

Researchers introduce REVEAL++, an advanced vision-language model that uses continuous phenotypic grouping to improve Alzheimer's disease risk prediction from retinal imaging data. Unlike prior discrete clustering approaches, the framework treats disease risk similarity as a learnable, differentiable signal, demonstrating superior performance on UK Biobank data for early cognitive decline detection.

Graph-Guided Universum Learning in Generalized Eigenvalue Proximal SVMs for Alzheimer's Disease Classification

Researchers have developed two improved machine learning models (UG-GEPSVM and IUG-GEPSVM) that use graph-based structures to enhance Alzheimer's disease detection from MRI scans. By treating mild cognitive impairment samples as intermediate data points with geometric relationships rather than independent variables, the models achieve 88.07% average accuracy and demonstrate superior performance compared to existing classification methods.

What Do LLMs Know About Alzheimer's Disease? Multi-loss Fine-Tuning and Probing for AD Detection

Researchers demonstrate that fine-tuned large language models, particularly BERT, T5, and Llama-1B, achieve state-of-the-art performance in detecting Alzheimer's disease from speech transcripts across multiple datasets. The study reveals how these models encode disease-related linguistic signals through fine-tuning, advancing the potential for early AD diagnosis through text analysis.
