Training method of PSO-BP neural network model, storage medium and terminal

Abstract

The invention discloses a training method of PSO-BP neural network model for heavy metal content prediction, a storage medium and terminal equipment. The training method includes: measuring content ofheavy metal of sample soil to acquire heavy metal content data of the sample soil; performing spectrum reflectivity treatment on the sample soil to acquire a spectrum reflectivity curve of the samplesoil after being treated; according to the heavy metal content data of the sample soil and the spectrum reflectivity curve of the sample soil after being treated, performing feature waveband selection to acquire feature waveband of the sample soil; building the PSO-BP neural network model; inputting the feature waveband of the sample soil into the PSO-BP neural network model for training study until the PSO-BP neural network model converges. Accuracy of soil heavy metal content estimation and predication through the model trained by the method is improved greatly.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to a training method, storage medium and terminal equipment of a PSO-BP neural network model for heavy metal content prediction Background technique [0002] Soil is a limited and important natural resource, and heavy metal pollutants in the environment have the characteristics of circulation and extremely difficult to degrade, especially the heavy metals in the soil are both enriched, which will eventually cause the existing or potential degradation of soil quality, ecological environment Deterioration and other phenomena, and can reach the human body through the food chain, directly endangering human health. For example, South China is one of the most important mineral belts in China. At present, many mineral resources are mainly distributed in the upper reaches or tributaries of the Pearl River Delta water system and the mountainous areas of important agri...
