Problems solved by technology

However, in practice, the length of the pulse signal sequence is usually longer, that is, the value of N is often relatively large, resulting in low efficiency of pooling the pulse signal sequence in the case of limited hardware resources, which in turn affects the input SNN network model data processing efficiency

Abstract

The invention provides a data processing method and device based on a spiking neural network. The method comprises the following steps: compressing each pulse signal sequence generated by input data to obtain each compressed code of the input data; and pooling each compressed code through a pulse neural network to obtain target data. According to the data processing method based on the pulse neural network provided by the embodiment of the invention, the pulse signal sequence is compressed to form the compressed code, so that the length of the compressed code is greatly reduced compared with the length of the pulse signal sequence, and the requirement on the pulse storage space is exponentially reduced during storage. And because the length of the formed compressed code is short, the calculation time can be shortened exponentially during pooling calculation, the pooling efficiency is improved, and the processing efficiency of the data input into the SNN network model is further improved.

Description

technical field [0001] The present application relates to the technical field of spiking neural networks, and in particular, to a data processing method and device based on spiking neural networks. Background technique [0002] With the development of brain science and brain-like computing technology, Spiking Neural Network (SNN) is considered to be a computing model close to the way of brain information processing, which can imitate the human brain to process data such as images or speech. The advantages of low power consumption and simple structure. [0003] In the related art, when using the spiking neural network to process data such as images or sounds, the SNN network model is used to encode input data, such as image frames or voice data, to form multiple pulse signal sequences based on pulse frequency coding, and then pass the SNN network model. Pooling is performed to pool multiple pulse signal sequences into one output to obtain the target result. [0004] The pul...
