I still come across the terms data science, AI, ML among others being used interchangeably to mean the same thing. As data professionals it is important to define and educate so everyone can talk the same language.
Data Science is the broad field of study that combines domain expertise, programming skills, data analytics and knowledge of mathematics and statistics to extract meaningful insights from data
Artificial Intelligence (AI) is the theory and development of computer systems able to simulate human intelligence. Branches of AI include machine learning, vision, expert systems, natural language processing (NLP), robotics and fuzzy logic.
Machine learning (ML) is a subset of AI involving algorithms that provide systems the ability to automatically learn and improve from experience without being explicitly programmed.
Deep Learning is a subset of ML that utilises artificial neural networks learning from large datasets to solve complex problems
