Abstract
Our first and key finding is that there is a logarithmic relationship between the CIWA-Ar score and the tremor energy in the [5,15] Hz range. Based on training on 84 recordings from 50 patients with the clinical diagnosis of AWS, and testing on a separate set of 33 patients with AWS, the proposed logarithmic relationship provides a CIWA-Ar Root Mean Square Error (RMSE) of 0.91 (with respect to a consensus rating from 3 expert physicians on a 7 point scale). This compares to a RMSE of 1.04 for junior physicians, 0.94 for junior nurses, 0.94 for senior nurses, and 0.95 for expert physicians.
