Embodiment Construction

[0025] The following describes in detail the embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to be used to explain the present application, but should not be construed as a limitation to the present application.

[0026] For some products, with regard to product value forecasting, due to the short forecast time, the probability of a product’s fundamental changes and emergencies occurring during the forecast period is relatively small. Technical data plays a leading role and influences Compared with the value prediction problem, the factors are highly concentrated, which greatly reduces the negative impact of "ignoring variable bias", and product value prediction is more sui...

Abstract

The invention relates to the technical field of data processing, in particular to a product value sorting prediction method and device, equipment and a storage medium, and the method comprises the steps: obtaining the current transaction data of a plurality of products; and inputting the current transaction data of the plurality of products into a preset product value prediction model to obtain an actual value feature of each product, and predicting a value sorting prediction result within a target duration based on the actual value feature of each product, the preset product value prediction model is obtained by performing multiple different sorting prediction training on a neural network based on the product transaction record data. Therefore, the problems of relatively poor prediction accuracy, relatively low prediction efficiency and the like of the current product value sorting are solved.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular, to a prediction method, device, device and storage medium for product value ranking. Background technique [0002] For some products, investors always expect to understand the market with the ability to surpass competitors in order to obtain excess returns. Therefore, quantitative analysis and prediction of some product markets to determine product value ranking will help investors understand this Pricing laws and influencing factors of complex systems. [0003] However, there are too many influencing factors for product value and complex patterns, and the input features cannot represent all the influencing factors, which leads to ignoring variable bias, especially when using machine learning models to predict product value ranking. This bias is due to the fitting ability of the model. Stronger is easier to be amplified, making the prediction performance of t...
