Machine learning

Machine learning (ML) is a subfield of artificial intelligence (AI) that gives computers the ability to learn without being explicitly programmed. ML algorithms are trained on data and then used to make predictions or decisions. ML is used in a wide range of applications, including image recognition, natural language processing, and fraud detection.

Supervised learning: In supervised learning, the ML algorithm is trained on a dataset that has been labeled with the correct answers. For example, an ML algorithm could be trained on a dataset of images of cats and dogs, and then used to classify new images of animals as either cats or dogs.
Unsupervised learning: In unsupervised learning, the ML algorithm is trained on a dataset that has not been labeled. The algorithm then finds patterns and structures in the data. For example, an ML algorithm could be trained on a dataset of customer purchase data, and then used to identify customer segments.
Reinforcement learning: In reinforcement learning, the ML algorithm learns by interacting with its environment. The algorithm receives rewards for good actions and punishments for bad actions, and it learns to adjust its behavior accordingly. For example, an ML algorithm could be trained to play a game by interacting with the game environment and receiving rewards for winning and punishments for losing.

ML is closely related to data engineering and data science. Data engineering is the process of designing and constructing the data pipelines and infrastructure that are needed to support ML algorithms. Data science is the process of using ML algorithms to extract insights from data. Together, data engineering and data science are essential for enabling organizations to use ML to achieve their business goals.
