Abstract

Alzheimer’s disease (AD) is an irreversible neurodegenerative disease, so early identification of Alzheimer’s disease and its early stage disorder, mild cognitive impairment (MCI), is of great significance. However, currently available labeled datasets are still small, so the development of semi-supervised classification algorithms will be beneficial for clinical applications. We propose a novel uncertainty-aware semi-supervised learning framework based on the improved evidential regression. Our framework uses the aleatoric uncertainty (AU) from the data itself and the epistemic uncertainty (EU) from the model to optimize the evidential classifier and feature extractor step by step to achieve the best performance close to supervised learning with small labeled data counts. We conducted various experiments on the ADNI-2 dataset, demonstrating the effectiveness and advancement of our method.
