Machine Learning (AI)

Machine Learning  as a way to achieve AI is one of  the current hot topic’s in the tech world. AI and machine learning algorithms aren’t new.  The field of AI dates back to the 1950s. An IBM researcher, Arthur Lee Samuels,  developed one of the earliest machine learning programs. He developed a self-learning program for playing checkers. He coined the term machine learning, and his approach to machine learning was explained in a paper published in the IBM Journal of Research and Development in 1959. [source IBM].

Computers use mathematical algorithms to learn, and different algorithms learn in different ways and are used for different solutions using ML.
