From aging to early-stage Alzheimer's: Uncovering handwriting multimodal behaviors by semi-supervised learning and sequential representation learning

作者:

Highlights:

• We propose a paradigm unveiling handwriting changes due to aging and Alzheimer‘s.

• Our new semi-supervised learning and sequential representation learning are key.

• Semi-supervised learning brings to light handwriting multimodal behavioral trends.

• Our sequential representation learning uncovers temporal feature representations.

• Classification based on temporal representations outperforms the state of the art.
