Abstract

The invention discloses a data processing method. The data processing method comprises the following steps: acquiring significant digits of data in various channels of various levels of a data model;determining fixed-point levels of the various channels on the basis of the significant digits; and carrying out fixed-point on data in the channels according to the fixed-point levels of the various channels to obtain first fixed-point data. The invention further discloses a data processing device and a computer readable storage medium. The fixed-point level of the various channels is determined according to the significant digits, fixed-point of different levels can be adopted by the different channels, the bytes of data are reduced, storage space is expanded, and thus, model operation rate is improved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data processing method, device and computer-readable storage medium. Background technique [0002] The concept of deep learning originated from the study of artificial neural networks. A multi-layer perceptron with multiple hidden layers is a deep learning structure. Deep learning combines low-level features to form more abstract high-level representation attribute categories or features to discover distributed feature representations of data. [0003] At present, when the data in the deep learning model is fixed-point, it is fixed-point to 8 bits. However, when some data in the deep learning model is fixed-point to 4 bits, it will not cause the loss of precision after the data is fixed-point, or when fixed-point When it is 8 bits, the resulting precision loss is not within the preset precision loss, and it needs to be fixed-point converted to 16 bits. If the...
