Simple Digit Recognition Using MATLAB with Backpropagation Neural Network

This is a straightforward digit recognition application that utilizes Backpropagation (BP) neural network for training and incorporates a user-friendly graphical user interface (GUI). The application enables users to identify digits through image recognition technology. Users simply input digital images into the application, which then processes them through the BP neural network training pipeline to generate recognition results. The implementation involves key MATLAB functions such as patternnet for neural network creation, train for network training, and sim for recognition inference. The GUI components are built using MATLAB's App Designer or GUIDE toolbox, handling image preprocessing steps including normalization and feature extraction before feeding data to the neural network. This application offers exceptional usability and accessibility, making it suitable for both beginners exploring machine learning concepts and experienced users seeking practical pattern recognition solutions.
