Researchers have developed a generalizable feature extractor for Alzheimer's disease-related brain MRI tasks, demonstrating the effectiveness of transfer learning in neuroimaging. By adapting a pre-trained 3D convolutional neural network (CNN) using Low-Rank Adaptation (LoRA) with only about 1% additional trainable parameters, the model achieved high accuracy in classifying cognitive states and predicting biomarkers. Notably, the adapted model performed well on unseen datasets without retraining, suggesting its potential as a reusable foundation model for Alzheimer's research, even with limited labeled data. AI
