The main difference between Artificial Intelligence (AI) and Machine Learning (ML) lies in their scope and functionality within the field of computer science.
Artificial Intelligence is a broad discipline focused on creating systems capable of performing tasks that typically require human intelligence. These tasks include reasoning, decision-making, problem-solving, understanding natural language, and visual perception. AI encompasses a wide range of techniques and methodologies, including rule-based systems, expert systems, evolutionary algorithms, and, notably, machine learning.
Machine Learning, on the other hand, is a Subset of AI that involves the development of algorithms and statistical models that enable computers to learn and improve from experience without being explicitly programmed for each specific task. ML systems identify patterns in data and use these patterns to make predictions or decisions. The key characteristic of machine learning is its ability to adapt and optimize performance as it is exposed to more data over time.
