Problems solved by technology

Since it takes a lot of input time for users to manually input destination information and causes inconvenience to passengers, how to provide users with destination recommendation services through the service platform is of great significance
[0004] Although the existing methods can also realize the prediction of the destination by manually selecting and combining the features in the user's historical orders, this manual method takes a lot of time and labor costs, and it is difficult for humans to find nonlinear feature combinations , the prediction accuracy of the user's destination is low

Abstract

The invention discloses a method and device for predicting a destination and a storage medium, and the method comprises the steps: obtaining historical order data, and generating training set data with a label according to the historical order data; constructing a plurality of decision trees according to the training set data, and generating a plurality of multi-feature combinations based on the plurality of decision trees; screening the multi-feature combination of which the prediction accuracy is higher than a first threshold according to the prediction effect of the decision tree; and classifying the users based on the multi-feature combination of which the prediction accuracy is higher than a first threshold, the corresponding decision tree and a set threshold, and performing personalized destination prediction according to a classification result. According to the invention, personalized prediction of the destination can be carried out, and the destination prediction effect is improved while the labor cost is saved.

Description

technical field [0001] The present invention relates to the technical field of data processing, and in particular, the present invention relates to a method, device and storage medium for predicting a destination. Background technique [0002] Online car-hailing has brought a lot of convenience to people's travel, and users can conveniently reserve vehicles through the service platform. [0003] When booking a vehicle, generally speaking, the user needs to define the destination by himself. Since it takes a lot of input time for users to manually input destination information and causes inconvenience to passengers, how to provide destination recommendation services for users through the service platform is of great significance. [0004] Although the existing methods can also realize the prediction of the destination by manually selecting and combining the features in the user's historical orders, this manual method takes a lot of time and labor costs, and it is difficult f...
