Query: A Machine Learning Approach to Digital Contact Tracing: TC4TL Challenge   Contact tracing is a method used by public health organisations to try
prevent the spread of infectious diseases in the community. Traditionally
performed by manual contact tracers, more recently the use of apps have been
considered utilising phone sensor data to determine the distance between two
phones. In this paper, we investigate the development of machine learning
approaches to determine the distance between two mobile phone devices using
Bluetooth Low Energy, sensory data and meta data. We use TableNet architecture
and feature engineering to improve on the existing state of the art (total nDCF
0.21 vs 2.08), significantly outperforming existing models.
