Embodiment 1

[0040] In order to solve the uneven situation of the above-mentioned e-commerce field sales prediction expert method and the simple moving average statistical method accuracy rate; the present invention uses 3 models; LightGBM, WaveNet (CNN+DNN), LSTM to historical sales data (Time Series; time Sequence TS) is weighted as the final prediction model after prediction.

[0041] LightGBM: Predict the prediction target as a regression problem; in product sales forecasting, it can effectively combine discrete features such as product attributes (such as categories, periodicity) and continuous features of continuous sales through time sliding windows. The traditional moving average method can only extract time-related statistical features, and cannot process category features; at the same time, it cannot predict multiple commodities (Mulit_Step) at one time. Specific predictions such as Figure 5 , which can solve the problem of predicting multiple commodities at a time.

Abstract

The invention discloses a model construction method based on machine learning. The model construction method comprises a data processing step of processing received historical data of a product to obtain product statistical characteristics and promotion characteristics; a data transmission step of transmitting the product statistical characteristics and the promotion characteristics to an LGB model, a WaveNet model and an LSTM model for data processing; and a prediction model construction step of weighting the data processed by the LGB model, the WaveNet model and the LSTM model to obtain a prediction model. The invention also provides a sales prediction method based on machine learning. According to the model construction method based on machine learning, a final prediction model is formed by mixing a plurality of models such as a classic time sequence model and a deep learning model, so that the prediction accuracy of product sales is greatly improved, and more accurate inventory management and operation planning data can be provided for a user.

Description

technical field [0001] The invention relates to the technical field of machine learning, in particular to a machine learning-based model building method and a sales forecasting method. Background technique [0002] At present, in the field of Internet + e-commerce; the traditional method of predicting the sales of each product based on the experience of business experts is called the expert method. Its advantage is fast and concise; the disadvantage is that the accuracy rate is uneven. Because the accuracy of sales forecast has a decisive impact on inventory management and operation planning. Therefore, improving the prediction accuracy of product sales has become a technical problem to be solved urgently by those skilled in the art. [0003] The existing implementation plan has the following methods: as the agricultural product production and marketing decision-making method, device and system provided in the invention authorized patent CN201510133375.X, according to the ...
