"MATLAB is a powerful tool for machine learning, with a wide range of built-in functions and toolboxes that can be used to develop and implement machine learning models. MATLAB projects for machine learning provide students and researchers with the opportunity to apply their knowledge of machine learning algorithms and techniques to real-world problems. Machine learning is a field of artificial intelligence that deals with the development of algorithms and models that can learn from data and make predictions or decisions without being explicitly programmed. Machine learning techniques can be applied to a wide range of applications, including image and speech recognition, natural language processing, and predictive modeling. "
