AI (Artificial Intelligence) and ML (Machine Learning) refer to a branch of computer science focused on the development of systems and algorithms that can perform tasks that typically require human intelligence, such as understanding natural language, recognizing patterns and making predictions.

ML is a subfield of AI and refers to the use of algorithms and statistical models to enable a system to improve its performance on a specific task over time, without being explicitly programmed. ML algorithms use data to train and learn, allowing the system to make predictions or take actions based on patterns in the data.

In practical applications, AI and ML are used in various fields such as computer vision, natural language processing, speech recognition, robotics, and decision-making systems. These technologies have the potential to revolutionize many industries and improve the quality of life for people around the world.
