python实现用逻辑回归识别和分类人工手写数字-Classifying MNIST digits using Logistic Regression

本文主要实现手写数字识别，利用多类逻辑回归与神经网络两种方法实现,并编写有GUI界面。(This paper mainly implements handwritten numeral recognition, using multiple logic regression and neural network to achieve two methods, and the preparation of a GUI interface.)

逻辑回归算法来进行分类，并计算查全率和召回率(Logical regression algorithm is used to classify .and to calculate recall and recall rate)
