  1. 1. The Use of Decision Trees to Detect Alzheimer's Disease

    Kandidat-uppsats, Umeå universitet/Institutionen för datavetenskap

    Författare :Janis Pettersson; [2021]
    Nyckelord :Decision Tree; Machine Learning; Alzheimer s Disease; Dementia; Open Access Series of Imaging Studies OASIS ; C4.5; CART; CHAID; Weka 3;

    Sammanfattning : Alzheimer's Disease is the most common disease of dementia, which may involve the decline of memory, communication, and judgement, yet it is hard to diagnose. The machine learning algorithms, Decision Trees, provide a possible solution to reduce the difficulty of the diagnosis process of Alzheimer's Disease. LÄS MER
