Dr. Jo, along with colleagues, published a research paper titled "Deep Learning Detection of Informative Features in tau PET for Alzheimer's Disease Classification" in BMC Bioinformatics (doi: 10.1186/s12859-020-03848-0) in 2020. The study developed a deep learning-based framework combining 3D CNN and LRP algorithms to identify informative features in tau PET images for Alzheimer's disease classification.
