This study focuses on effectively modeling multimodal longitudinal data, particularly in the field of biomedicine, to address the lack of approaches in the literature.
The study introduces Longitudinal Ensemble Integration (LEI), a novel framework for sequential classification that outperformed existing methods in the early detection of dementia.
LEI's superiority is attributed to its utilization of intermediate base predictions from individual data modalities, leading to better integration over time and consistent identification of important features for dementia prediction.
The research highlights the potential of LEI for sequential classification tasks involving longitudinal multimodal data.
