Explainable CNN-attention Networks (C-Attention Network) for Automated Detection of Alzheimer's Disease

no code implementations25 Jun 2020 Ning Wang, Mingxuan Chen, K. P. Subbalakshmi

In this work, we propose three explainable deep learning architectures to automatically detect patients with Alzheimer`s disease based on their language abilities.

Personalized Early Stage Alzheimer's Disease Detection: A Case Study of President Reagan's Speeches

no code implementations WS 2020 Ning Wang, Fan Luo, Vishal Peddagangireddy, K. P. Subbalakshmi, R. Chandramouli

In this paper, we show that machine learning-based unsupervised clustering of and anomaly detection with linguistic biomarkers are promising approaches for intuitive visualization and personalized early stage detection of Alzheimer`s disease.
