Abstract

The invention relates to a vehicle source transaction probability prediction method and device, an electronic device and a storage medium. The vehicle source transaction probability prediction method comprises the following steps: obtaining dimension data of a predicted vehicle source; using a vehicle source transaction prediction model to process the dimension data to obtain a prediction value, wherein the vehicle source transaction prediction model is trained based on a LightGBM model and is trained to predict a prediction transaction value of the vehicle source in a preset time period; and determining the transaction probability of the predicted vehicle source in the preset time period according to the predicted transaction value. According to the invention, the problem of low accuracy of the prediction result of the vehicle transaction probability in the related technology is solved, and the accuracy of the prediction result of the vehicle transaction probability is improved.

Description

technical field [0001] The present application relates to the field of machine learning, in particular to a method, device, electronic device and storage medium for predicting the transaction probability of vehicle sources. Background technique [0002] With the development of the domestic economy, automobiles have become a must-have travel tool for families, and the annual circulation of second-hand cars in the market is also increasing. For second-hand car trading platforms, the efficiency of vehicle circulation greatly affects the revenue of the platform. If the transaction probability of vehicles on the platform can be evaluated, vehicles with different transaction probabilities can be given corresponding operating strategies to quickly match different car purchase intentions. Car dealers can increase the turnover rate of vehicles. [0003] In the related art, methods for estimating the transaction probability of used cars are mainly classified into rule-based methods o...
