Embodiment Construction

[0056] The present invention is described below in combination with specific embodiments.

[0057] In a non-limiting embodiment, in terms of weather forecasting, using the method of the present invention, it is only necessary to provide digital historical data such as maximum temperature and minimum temperature within a period of time, and the future maximum temperature and minimum temperature can be predicted and other information, and there is no need to provide other additional data assistance in the process, and the prediction results can also be intuitively reflected.

[0058] Taking temperature prediction as an example, it provides temperature information in N rows and 2 columns, and the column attributes are the highest temperature and the lowest temperature respectively. After receiving the raw data, the device starts preprocessing, that is, the raw temperature data of N rows and 2 columns is normalized to a value between 0 and 1; then the input and output matrix of th...

Abstract

The invention discloses a weather prediction method, which includes the steps: providing temperature information values, normalizing the temperature information values, establishing an input/output matrix of a training sample, predicting weather through a neural network based on the output matrix, and the like. Original training data modes can be automatically distinguished by an improved algorithm, and are subjected to sample establishing and normalization. The weather prediction method is applicable to various complex circumstances, is high in flexibility, and needs no auxiliary data to complete prediction, and prediction results can be restored within a numeric range corresponding to original training data.

Description

technical field [0001] The invention mainly relates to technical fields such as weather forecasting and data mining. Background technique [0002] 1. Data mining technology: [0003] With the development of storage devices and database technology, data storage is no longer a problem. On the contrary, people have begun to feel overwhelmed by a large amount of data. Therefore, there is an urgent need for a scientific method to convert massive data into practically meaningful knowledge for people. And law, data mining is the technology produced under this background. [0004] In the late 1980s, data mining quietly emerged as a new research field. The purpose of data mining research is to discover those hidden information with specific rules that people are interested in in large data sets. With the development of data mining, this technology is applied in many fields such as business management, government office, scientific research and engineering development. [0005] In...
