The invention relates to the technical field of
air temperature forecasting, and discloses an
air temperature forecasting model construction method based on
machine learning, which comprises the following steps of: collecting live data, namely, high-low temperature and rainfall per 3h of 78 national meteorological stations in Hubei province, and EC high-resolution mode analysis and forecasting data; preprocessing the data, cleaning the
original data, and generating a sample set; utilizing a
machine learning method to establish a 3h-by-3h
air temperature forecasting model of the sub-stations; inputting the
training set data in the three groups into an air
temperature forecasting model, and extracting the features of the
training set data; outputting a result, and performing applicability evaluation on the air
temperature forecasting model; optimizing the air
temperature forecasting model, inputting the
test set or new data into the air temperature forecasting model, and calculating an average absolute error; and deploying the trained model on an intelligent grid service platform to carry out model business. In conclusion, the temperature forecasting capability is improved, and the automatic, objective and intelligent forecasting level is improved.
