Machine learning and deep learning are both subfields of artificial intelligence, but they differ in complexity and application. Machine learning focuses on algorithms that learn from data through statistical techniques and require less computational power compared to deep learning. Deep learning, a subset of machine learning, involves neural networks with many layers, requiring large datasets and significant computational resources to train. In formal education, machine learning may be introduced as a foundational concept, while deep learning is usually tackled in advanced courses. Informally, deep learning is often pursued by enthusiasts or practitioners via online tutorials and self-learning platforms.
