Detailed Documentation
This project implements the Backpropagation algorithm for neural networks to recognize handwritten digits. The program is developed in MATLAB and contains directly executable code. The implementation includes key neural network components such as forward propagation, error calculation, and weight updates through gradient descent. Additionally, it supports input data preprocessing techniques like normalization and standardization to enhance recognition accuracy. The code structure features modular functions for network initialization, training iteration management, and performance evaluation metrics including confusion matrix analysis and accuracy calculation. Users can customize network architecture parameters such as hidden layer sizes and activation functions (sigmoid/ReLU) through configurable variables.
