Abstract

The invention provides a data compression method, which comprises the following steps: obtaining a plurality of values of a parameter and an occurrence probability of each of the plurality of values;comparing the occurrence probability with a preset threshold value, wherein the value, smaller than the preset threshold value, of the occurrence probability is a first set of values, and the value, larger than or equal to the preset threshold value, of the occurrence probability is a second set of values; preprocessing the first group of values; and encoding the second set of values and the preprocessed first set of values. By means of the data compression method, the maximum codeword length can be reduced advantageously, so that the requirement of the code table for the storage space is reduced. The invention further provides a corresponding data compression device and a computer readable storage medium.

Description

technical field [0001] The invention belongs to the field of data processing, and in particular relates to a data compression method and device and a computer-readable storage medium. Background technique [0002] With the continuous enhancement of computing and processing capabilities of various electronic devices and the increase of communication between electronic devices, the amount of data stored in electronic devices and the amount of data transmitted between electronic devices are also increasing. A typical example is the neural network used in the field of artificial intelligence. With the increasing computing power and the increasing complexity of the problems to be solved, and the gradual increase in the performance requirements of the neural network, the depth of the deep neural network is getting deeper and deeper. , The scale is getting bigger and bigger, and the large-scale neural network corresponds to a large number of parameters. The storage and transmission...
