Embodiment Construction

[0082] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0083] Refer to attached figure 1 , further describe in detail the steps realized by the present invention.

[0084] Step 1, preprocessing the meteorological data.

[0085] In the first step, a 3×2 two-dimensional matrix is ​​constructed using a one-dimensional data containing six attribute values.

[0086] The six attribute values ​​refer to atmospheric pressure, dry bulb temperature, dew point temperature, wind speed, wind direction, and total cloud cover.

[0087] The construction method of the 3×2 two-dimensional matrix is ​​that the first two values ​​of the six attribute values ​​are sequentially used as the first row of the two-dimensional matrix, and the middle two values ​​of the six attribute values ​​are sequentially used as the first row of the two-dimensional matrix. In the second row, the last 2 values ​​of the 6 attribute values ​​are used a...

Description

technical field [0001] The invention belongs to the technical field of computers, and further relates to a method for filling meteorological data based on a convolution automatic encoding and decoding algorithm in the technical field of meteorological data processing. The present invention can be applied to specific application scenarios such as meteorological data processing and meteorological data analysis. Aiming at the limitations of existing meteorological data filling algorithms, the missing meteorological data can be filled according to the correlation between the attribute characteristics of meteorological data learned many times. its weather data value. Background technique [0002] Fill Gap is a method due to missing data. Missing data refers to the data that should have been obtained but were not obtained for some reason at the time of data collection. It refers to the incomplete value of one or some attributes in the existing data set. In scientific research, ...
