An online learning chip based on a stacked width learning model

Abstract

The invention provides an online learning chip based on a stacked width learning model, which includes a main controller, a memory, and a reconfigurable processing unit array; The reconfigurable processing unit array outputs initialized configuration information; the reconfigurable processing unit array configures each feature node and enhanced node one-to-one to the processing unit according to the initialized configuration information; the input memory inputs the identification training sample features into the model circuit; Output the processing result to the output memory, and then feed back the performance value information to the main controller; judge the calculated performance value to update the width configuration information or depth configuration information in the configuration information memory; when the calculated performance value ≥ set When the performance threshold is set, the online learning stops and the online learning chip solidifies. The chip has low computing resources, low power consumption, strong real-time performance, and online learning capabilities.

Description

technical field [0001] The present invention relates to the technical field of a stacked width learning model, and more specifically, relates to an online learning chip based on a stacked width learning model. Background technique [0002] The Broad Learning System (BLS) is an efficient and shallow incremental neural network learning model. It maps the input into a set of feature nodes, which in turn maps the feature nodes into a set of augmentation nodes. The output of the width model can be expressed as a weighted combination of feature nodes and enhancement nodes. The width learning system can use existing nodes to obtain new feature nodes or enhanced nodes through some kind of mapping such as random mapping, and dynamically add new feature nodes or enhanced nodes to achieve better learning effects. [0003] The width learning system has similar performance to the deep neural network, but compared with the deep neural network, the width learning system has low complexit...

Problems solved by technology

The information content of a single configuration information is small, and it has a real-time switching effect. Therefore, it belongs to a dynamic reconstruction processor and is an ideal chip for realizing the operation of online learning neural networks. However, it is still blank to use CGRA to realize the operation of online learning neural networks.
