The method predicts the value that is the mean prediction of all individual regression tree predictors. Like most machine learning techniques, regression random forest has some free parameters that can be optimized. There are among others, the number of trees, number of predictor variables randomly...
This article surveys measurements of celestial (chiefly solar) altitudes documented from twelfth- and thirteenth-century Latin Europe. It consists of four
of activity at the Maragha observatory, Shams al-Dīn Muḥammad al-Wābkanawī (c. 1254–1320) adopted all of al-Maghribī’s parameter values in hisZīj, but decreased his value for the mean longitude of the moon at epoch by 0;13,11∘. By comparing the times of the new moons ...
