Abstract
This application discloses a data compression method and a computing device. The disclosed method is applied to the computing device. The method includes receiving, by the computing device, to-be-compressed data, and identifying a data type of the to-be-compressed data. The method further includes selecting one or more data compression models based on the identified data type and compressing the to-be-compressed data based on the selected one or more data compression models.
Claims15
A data compression method performed by a computing device, comprising:
- receiving, by a first processor of the computing device, to-be-compressed data;
- obtaining, by the first processor of the computing device, M data type identification models;
- determining, by the first processor of the computing device, M probability sets corresponding to the to-be-compressed data based on the M data type identification models;
- identifying, by the first processor of the computing device, a data type of the to-be-compressed data by obtaining P intermediate values based on the M probability sets and weight ratios of the M data type identification models, the data type of the to-be-compressed data corresponding to an intermediate value in the P intermediate values and that is greater than an accuracy threshold, the data type including a text type, a picture type, or a video type;
- selecting, by the first processor of the computing device, a data compression model based on the data type;
- sending, by the first processor of the computing device, the to-be-compressed data and information related to the selected data compression model to a second processor of the computing device;
- compressing, by the second processor of the computing device, the to-be-compressed data to obtain compressed data based on the selected data compression model;
- and
- sending, by the second processor of the computing device, the compressed data to the first processor of the computing device.
