Xijia (Simon) Wei

Brief biography
I am currently a PhD student at University College London (UCL) under the supervision of Prof Nadia Berthouze , Dr Youngjun Cho and Dr Kevin Chetty. I focus on sensor fusion based ubiquitous computing. Specifically, I explore multimodal machine learning architecture to allow models automatically learn communicative features from multisensory data without human intervention to make robust inferences under various real-life scenarios. I am currently developing a novel wireless sensing system that can recognise the quality of body movement and physiological signals.
Prior to joining UCL, I studied Artificial Intelligence (MSc) under the supervision of Dr Valentin Radu and Electronics and Electrical Engineering (BEng), supervised by Prof Tughrul Arslan, both at the University of Edinburgh.
