Domain Adaptation for IMU Data to Enhance Objective Assessment of Friedreich Ataxia

Tran, M., Ranaweera, K., Ngo, T., Pathirana, P., Milne, S., Horne, M., Delatycki, M., & Corben, L. (2026). Domain Adaptation for IMU Data to Enhance Objective Assessment of Friedreich Ataxia. IEEE Journal of Biomedical and Health Informatics, PP. doi:10.1109/JBHI.2026.3702417 

 Our approach leverages a convolutional neural network (CNN) architecture to automatically learn high-level representations from raw IMU signals, minimizing reliance on manual feature engineering. Central to our method is a two-stage training strategy that incorporates domain adversarial learning, enabling knowledge transfer between two IMU-based assessment tools: the Ataxia Instrumented Measures cup (AIM-C) and spoon (AIM-S). This strategy enhances learning from each device by exploiting shared underlying representations.
