C++ Machine Learning Project: Digit Recognition with Support Vector Machine (SVM) Overview This project aims to implement a digit recognition system using Support Vector Machine (SVM) in C++. SVM is a powerful supervised learning algorithm used for classification tasks.

Features Dataset: Utilize the MNIST dataset for training and testing. Preprocessing: Implement preprocessing steps such as normalization and feature extraction. SVM Implementation: Develop SVM classifier using libraries like LIBSVM or implement from scratch. Training: Train the SVM model on the training dataset. Testing: Evaluate the model's accuracy on the test dataset. Prediction: Implement a function to predict digits based on input images. Performance Metrics: Calculate and display metrics like accuracy, precision, and recall. User Interface (Optional): Develop a simple CLI or GUI for interacting with the model. Technology Stack Language: C++ Libraries: LIBSVM (or similar for SVM implementation) Dataset: MNIST dataset (or similar digit recognition dataset) Development Tools: IDE like Visual Studio or Code::Blocks Implementation Steps Dataset Preparation: Download and preprocess the MNIST dataset. SVM Model Development: Implement SVM classifier using chosen library or custom implementation. Training: Train the SVM model on the training dataset. Testing and Evaluation: Test the model on the test dataset and calculate performance metrics. Prediction Function: Implement a function to predict digits based on user input. User Interface (Optional): Develop a simple interface for easy interaction with the model. Example Code Snippet (SVM Training) cpp Copy code // Example using LIBSVM for SVM training

#include #include "svm.h"

int main() { // Load training data svm_problem prob; // Initialize prob with your training data (features and labels)

// Set SVM parameters
svm_parameter param;
svm_set_default_parameter(&param);
param.svm_type = C_SVC;
param.kernel_type = RBF;
param.gamma = 0.5;

// Train SVM model
svm_model *model = svm_train(&prob, &param);

// Save model for future use
svm_save_model("svm_model.model", model);

// Free memory
svm_free_and_destroy_model(&model);
svm_destroy_param(&param);

return 0;

} Conclusion This project provides a hands-on experience with machine learning in C++, focusing on implementing a digit recognition system using SVM. It enhances understanding of SVM algorithms, dataset handling, and model evaluation in a practical context.

Further Enhancements Experiment with different SVM kernels (linear, polynomial). Optimize hyperparameters for better accuracy. Extend to recognize more complex images or datasets beyond digits.
