Enriching Neural Models with Targeted Features for Dementia Detection

Abstract: Alzheimer's disease (AD) is an irreversible brain disease that can dramatically reduce quality of life, most commonly manifesting in older adults and eventually leading to the need for full-time care. Early detection is fundamental to slowing its progression; however, diagnosis can be expensive, time-consuming, and invasive. In this work we develop a neural model based on a CNN-LSTM architecture that learns to detect AD and related dementias using targeted and implicitly-learned features from conversational tr… Show more

“…We used stochastic gradient descent + momentum (SGD + Momentum) [42] as the optimizer for training. Since the cookie theft sub-dataset is unbalanced we added a class weight correction by increasing the penalty for misclassifying the less frequent class during model training to reduce the affect of data bias, as in [12]. The class weight correction ratio used in this paper is 7 : 3.…”
