Title
(EN) Indoor and outdoor mark distinguishing method, classifier training method and device and medium
(ZH) 室内外标记的区分方法、分类器的训练方法及设备和介质
Abstract
(EN)
The invention discloses an indoor and outdoor mark distinguishing method, a classifier training method, classifier training equipment and a medium. The distinguishing method comprises the steps of collecting measurement report data of a target user; inputting the measurement report data of the target user into a random forest classifier for classifying indoor and outdoor marks of the user; and determining indoor and outdoor marks of the target user according to classification calculation of the random forest classifier. The misjudgment rate is effectively reduced in the aspect of determining the indoor and outdoor marks of the user, and the real-time performance in the process of determining the indoor and outdoor marks of the user is effectively guaranteed.
