Second-hand vehicle pricing method, device and equipment and computer readable medium

Abstract

The invention provides a second-hand vehicle pricing method, a device, equipment and a computer readable medium. The method comprises the following steps: a parameter acquisition step, namely obtaining vehicle parameters of a second-hand vehicle to be priced; a data processing step, acquiring reference vehicle parameters based on the vehicle parameters; a pricing model generation step of constructing n vehicle pricing models based on the vehicle parameters and the reference vehicle parameters, and weighting the n vehicle pricing models by using BOOST to obtain a vehicle weighted pricing model,and a pricing step of obtaining pricing of a second-hand vehicle by using the vehicle weighted pricing model based on the vehicle parameters. According to the invention, a data set expansion mode isprovided; according to the method, the pricing of the second-hand vehicle is more objective and accurate, a single-model BOOST fusion mechanism is provided, the pricing result of the fused weighted pricing model is more accurate, a profit rate calculation mode is provided, the retail price and auction price of the second-hand vehicle can be estimated at the same time, and the pricing efficiency and accuracy are improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a used car pricing method, device, equipment and computer readable medium. Background technique [0002] At present, with the improvement of people's living standards, the speed of car renewal is getting faster and faster. According to the data released by the China Automobile Dealers Association, the transaction volume of second-hand cars in my country reached 10.3907 million in 2016, breaking through 10 million for the first time. The auto market is going through a blowout development stage. In the second-hand car market, second-hand cars are non-standard products, and there is no unified pricing method. Currently, the pricing services in the market are uneven, the pricing coverage is not high, and the pricing is inaccurate. It is impossible to buy and sell second-hand cars for consumers and car dealers. Cars provide accurate price services. Therefore, in the tr...

Problems solved by technology

[0003] In the existing technology, only the existing data set is used for training. When the existing data set is small, the pricing deviation of used cars is relatively large. In the existing technology, the existing pricing model is simply synthesized, and the pricing result is It is still not ideal, and the pricing function of used cars in the existing technology is single, and it is impossible to give auction prices and retail prices at the same time, and it is also impossible to calculate profit margins
