Machine Learning vs Deep Learning | Differences and Use Cases

Machine learning and deep learning are two branches of artificial intelligence (AI) that enable machines to learn from data without being explicitly programmed. These techniques are used to make predictions or decisions based on patterns in large data sets.

Machine learning involves the use of statistical algorithms and mathematical models to identify patterns in data, and uses these patterns to make predictions or decisions. For Use Case, machine learning can be used to recommend movies to a user based on their viewing history, or to detect fraudulent transactions in a credit card dataset.

Deep learning is a subset of machine learning that involves the use of artificial neural networks to model complex patterns in data. These neural networks are designed to learn from data in a way similar to how the human brain processes information. Deep learning is particularly useful for applications involving images, speech, and natural language processing, and has been used to develop self-driving cars, voice assistants, and image recognition software.

Both machine learning and deep learning are rapidly growing fields that are revolutionizing the way we interact with technology, and are increasingly being used in a wide range of applications across industries.
