Abstract

The embodiment of the invention discloses a method and system for recognizing handwritten numbers. Samples in original space are mapped to hidden space, and then the optimum target dimensionality (namely, the number of negative eigenvalues) of the samples in the hidden space is determined, so that the samples in the hidden space have the better linear separability after being mapped to low-dimensional space, and therefore the recognition rate of handwritten number recognition is improved.

Description

technical field [0001] The invention relates to the field of pattern recognition, more specifically, to a handwritten numeral recognition method and system. Background technique [0002] Handwritten digit recognition has always been a research hotspot in the field of pattern recognition. In modern society, there are countless application fields related to handwritten digit recognition, such as mail sorting, taxation, finance and other fields. When it comes to digital recognition, people often have high requirements for the precision and accuracy of the recognition system. With the rapid development of the economy, there are more and more financial statements and checks to be processed every day. If it can be automatically processed by computer, it can save a lot of financial resources, material resources and manpower. Therefore, one of the key links in the design of a processing system for this type of problem is to design a digital recognition method with high reliability...
