Embodiment Construction

[0035] The content of the invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] Handwriting recognition is a relatively mature technology in both theory and application. Due to the widespread popularization of mobile terminals, this technology is widely used. The present invention is mainly based on establishing an association model of data uncertainty and data relationship uncertainty to evaluate the effect of handwriting recognition.

[0037] Such as figure 1 As shown, the convolutional neural network handwriting recognition sorting stability evaluation system of the present invention includes three modules: a handwriting recognition module, a parameter estimation module and an uncertainty calculation module. The handwriting recognition module is a convolutional neural network, which inputs handwriting data, and then outputs the predicted probability that the handwriting belongs to each category through t...

Abstract

The invention relates to a system and method for evaluating the stability of convolutional neural network handwriting recognition and sorting effects, including a convolutional neural network handwriting recognition module, a parameter estimation module and an uncertainty calculation module. Among them, the convolutional neural network handwriting recognition module takes the user's handwritten data as input data, passes through the convolutional neural network (CNN), and finally outputs the predicted classification probability, and sorts according to this classification; the parameter estimation module uses the convolutional neural network (CNN) )'s handwriting recognition module output: take the predicted probability of the recognition module as input, and use statistical methods to estimate the parameters required for the calculation of the uncertainty of the relationship; the uncertainty calculation module takes the parameters output by the parameter estimation module as input data , by designing a fusion probabilistic calculation model of data uncertainty and data relationship uncertainty, to estimate the stability of convolutional neural network handwriting recognition ranking results.

Description

technical field [0001] The invention belongs to the field of effect evaluation, and in particular relates to a system and method for evaluating the stability of handwriting recognition and sorting by a convolutional neural network. Background technique [0002] Handwriting recognition refers to the process of informatizing the orderly trajectory generated when writing on a handwriting device into the internal code of Chinese characters. In fact, it is a mapping process from the coordinate sequence of the handwritten trajectory to the internal code of Chinese characters. It is the most natural human-computer interaction. , One of the most convenient means. With the popularization of mobile information tools such as smart phones and PDAs, handwriting recognition technology has also entered the era of large-scale application. [0003] The standard for evaluating the quality of a handwritten character is mainly determined by the accuracy of the recommended characters after reco...
