This article describe about Machine Learning, which is a type of artificial intelligence that provides computers with the ability to learn without being explicitly programmed. Machine Learning focuses on the development of computer programs that can teach themselves to grow and change when exposed to new data. It is important because as models are exposed to new data, they are able to independently adapt. They learn from previous computations to produce reliable, repeatable decisions and results. Machine Learning algorithms are often categorized as being supervised or unsupervised. Supervised algorithms can apply what has been learned in the past to new data. Unsupervised algorithms can draw inferences from datasets.
