Artificial Intelligence,Machine Learning, Deep Learning: Defining the Terms

Because of the rapid growth of the technology, there may confusion in differentiating the terms artificial intelligence (AI), machine learning (ML) and deep learning (DL). While the concepts are interrelated, there is a clear distinction in the terms.

AI is the all-encompassing concept involving the simulation of intelligent behavior in computers. When a machine completes tasks based on a set of stipulated rules that solve problems (algorithms), this is called artificial intelligence.

ML is a category of algorithm that allows software applications to become more accurate in predicting outcomes without being explicitly programmed. While ML algorithms can be used for many different tasks including supporting AI, AI can use methods other than ML.

DL is a technique that involves a family of algorithms that process information in deep “neural” networks. An algorithm is considered to be deep if the input data is passed through a series of nonlinearities or nonlinear transformations before it becomes output. DL is an area of ML research with the objective of moving ML closer to AI.
