Accuracy metrics to compare the analytical models of LS12 and this work, in addition to our restricted ML model.

Metric	LS12	New model	ML
RMSE	0.111	0.116	0.11
Med. Abs. Err.	0.0223	0.0054	0.004
Med. Rel. Err.	0.158	0.059	0.098

Notes. RMSE is the root mean squared error, med. abs err is the median absolute error, and med. rel err is the median relative error.

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.

Initial download of the metrics may take a while.
