Abstract

The invention provides a data processing method, device and equipment. The method comprises the steps: generating a sub-data set for target data after the target data of a target row in an input dataset is obtained for the input data set with a plurality of rows and a plurality of columns; determining a first storage position corresponding to the target data, and storing a sub-data set corresponding to the target data into a first storage medium according to the first storage position; determining a second storage position corresponding to initial data in an output data set, and reading a sub-data set corresponding to the initial data from the first storage medium according to the second storage position; and obtaining an output data set according to the sub-data set corresponding to theinitial data. According to the technical scheme, frequent execution of data reading operation is avoided, bandwidth is saved, and reading and writing efficiency is remarkably improved.

Description

technical field [0001] The present application relates to the Internet field, in particular to a data processing method, device and equipment thereof. Background technique [0002] In machine learning technology, CNN (Convolutional Neural Network, Convolutional Neural Network) is a feed-forward neural network, its artificial neurons can respond to surrounding units within a part of the coverage, and it has excellent performance for large-scale image processing. CNN is a multi-layer neural network, each layer is composed of multiple two-dimensional planes, and each plane is composed of multiple independent neurons. Generally, CNN can be composed of a convolutional layer and a pooling layer. The function of the convolutional layer is to extract various features of the image. The function of the pooling layer is to perform two feature extractions on the original features to reduce the feature resolution. Drastically reduce training parameters and reduce the degree of model ove...
