Problems solved by technology

[0004] In the prior art, the common method of model compression is to prune the model (that is, delete the smaller parameters in the model or the parameters that meet certain conditions), and store the parameters in the form of a sparse matrix, so that although the compression effect, but the accuracy loss of the model is also inevitable; in addition, there are also compression methods that adopt the method of retraining the cropped model to reduce the loss of model accuracy, but the computing performance when using the model to reason and predict is significantly reduced

Embodiment Construction

[0020] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0021] The core principle of the present invention: the parameter data of the convolutional layer and the fully connected layer in the pre-trained convolutional neural network model are cyclically retrained as discrete data in the preset format, and the converted model has no loss of precision; the preset format Discrete data is stored in low bits.

[0022] Among them, the parameter data of the convolutional layer and the fully connected layer in the model are all in FP32 format (32-bit floating-point storage format).

[0023] Further, before the parameter data of the convolutional layer and / or the fully connected layer in the convolutional neural network model are cyclically trained to obtain the d...

Abstract

The invention provides a convolutional neural network model based data processing method and device. The method includes steps: cyclically training parameter data of a convolutional layer and / or a full connection layer in a convolutional neural network model to acquire discrete data in a preset format; storing the discrete data in the preset format by preset bits. According to the technical scheme, the parameter data are converted into the discrete data which are then stored by the preset bits, and consequently compression storage of the model is realized while accuracy loss of the model after conversion is avoided; due to adoption of the discrete data in the preset format, operation efficiency is greatly improved.
