Abstract

Wearable devices and mobile sensors enable the real-time collection of an
abundant source of physiological and behavioural data unobtrusively. Unlike
traditional in-person evaluation or ecological momentary assessment (EMA)
questionnaire-based approaches, these data sources open many possibilities in
remote patient monitoring. However, defining robust models is challenging due to
the data's noisy and frequently missing observations.

This work proposes an attention-based Long Short-Term Memory (LSTM) neural
network-based pipeline for predicting mobility impairment based on WHODAS 2.0
evaluation from such digital biomarkers. Furthermore, we addressed the missing
observation problem by utilising hidden Markov models and the possibility of
including information from unlabelled samples via transfer learning. We validated
our approach using two wearable/mobile sensor data sets collected in the wild and
socio-demographic information about the patients.

Our results showed that in the WHODAS 2.0 mobility impairment prediction task,
the proposed pipeline outperformed a prior baseline while additionally providing
interpretability with attention heatmaps. Moreover, using a much smaller cohort
via task transfer learning, the same model could learn to predict generalised
anxiety severity accurately based on GAD-7 scores.
