What's Happening?
A recent study has employed advanced deep learning techniques to improve the early detection of Alzheimer’s disease using MRI data. The research utilized various models, including EfficientNetB2, InceptionV3, and RegNetx006, on rescaled MRI images to diagnose Alzheimer’s at early stages. The study involved 24,661 neuroimaging data points, processed using Google Colab infrastructure with TensorFlow and Python. The dataset was divided using stratified 10-fold cross-validation to address class imbalance issues. The ADNI-3 dataset, which includes genetic, clinical, cognitive, imaging, and biochemical biomarkers, was central to the analysis. The study also introduced a new model combining EfficientNetB2 with a Feature Pyramid Network (FPN) to enhance multi-scale feature extraction, crucial for identifying early signs of Alzheimer’s.
