Traditional Chinese medicinal material supply and demand relationship prediction method and device based on machine learning and medium

Abstract

The invention discloses a traditional Chinese medicinal material supply and demand relationship prediction method based on machine learning, and the method comprises the steps: obtaining a past year ecological environment data set and a past year yield data set of each traditional Chinese medicinal material production area, and inputting the data sets into a CNN-LSTM network model based on an attention mechanism for training; the CNN-LSTM network model based on the attention mechanism is used for predicting the yield data of the traditional Chinese medicinal materials in the next year; acquiring a past year sales volume data set of the traditional Chinese medicinal materials, inputting past year sales volume data into the hybrid prediction model, and predicting the sales volume data of the traditional Chinese medicinal materials in the next year; and determining a supply-demand relationship according to the predicted traditional Chinese medicinal material yield data and the traditional Chinese medicinal material sales volume data. The method can accurately predict the excess and sales volume of the medicinal materials in the next year based on the machine learning algorithm according to the yield data and sales volume data of the medicinal materials over the years, and determines the production-marketing-supply-demand relationship of the medicinal materials in the next year according to the prediction result, thereby providing reliable data support for employees in the medicinal material industry, and improving the medicinal material quality. And a correct operation decision can be made.

Description

technical field [0001] The invention belongs to the technical field of neural networks, and in particular relates to a method, device and medium for predicting the relationship between supply and demand of medicinal materials based on machine learning. Background technique [0002] The source of the Chinese herbal medicine industry lies in the planting of Chinese herbal medicines, and Chinese herbal medicines are the most special economic crops. Most of the Chinese herbal medicines have a longer growth cycle than ordinary crops, so they are much more affected by their ecological environment than ordinary crops, and different medicinal materials are affected by their The influence of growing conditions in the place of origin may also be different. However, if the current planting of medicinal materials in the place of origin is violated by the harsh ecological environment, the output, sales volume and price of the entire Chinese herbal medicine industry chain will be greatly ...
