Abstract

The invention provides a data storage method of a weight matrix. The method comprises the following steps: generating a connection matrix, a data type table and a special value table according to the weight matrix; storing a connection matrix, a data type table and a special value table; wherein the connection matrix and the weight matrix have the same structure, and each element of the connection matrix is the connection type of the weight value of the corresponding element in the weight matrix; the connection type is divided into valid connection and invalid connection; the data type table comprises data types which are sequentially arranged and correspond to the weight values which are effectively connected in the weight matrix; the data type comprises a special value type and a plurality of preset value types, each preset value type corresponds to a preset weight value of one effective connection, the special value type corresponds to a special weight value, and the weight values of other effective connections except the preset weight values are all special weight values; the special value table comprises all special weight values which are sequentially arranged in the weight matrix. The invention also provides a weight matrix data acquisition method and apparatus, and an electronic device.

Description

technical field [0001] The present disclosure relates to the field of brain-like computing, and in particular, to a method for storing data of a weight matrix, a method and apparatus for acquiring data of a weight matrix, and an electronic device. Background technique [0002] Brain-like computing technology has been widely used in intelligence science, cognitive science, information processing, artificial intelligence and other fields, such as image (video) recognition, image (video) processing, speech recognition, etc. [0003] The human brain includes a large number of neurons (such as about 100 billion), and the brain-like chip (neuromorphic chip) simulates the work of the human brain by setting a large number of electronically simulated neurons. The working process of neurons also needs to use a lot of "weights (such as connection weights)", these weights can exist in the form of "weight matrix", that is, each element of the weight matrix is ​​a weight value (such as a ...
