Understanding the difference between Machine Learning and Artificial Intelligence Introduction Machine learning and artificial intelligence (AI) are two closely related fields of study that are often used interchangeably, but they are different. Understanding the difference between them is crucial for anyone interested in working with or learning about these technologies. What is Machine Learning? Machine learning is a subfield of AI that focuses on developing algorithms and statistical models that enable computers to learn from data and make predictions or decisions without being explicitly programmed. It involves using techniques like supervised learning, unsupervised learning, and reinforcement learning to train models on large amounts of data and then using these models to make predictions or decisions in new, unseen situations. What is Artificial Intelligence? Artificial Intelligence, on the other hand, is a broader field that encompasses machine learning and other techniques such
