Data science is an interdisciplinary field that uses statistical, computational, mathematical, and domain-specific methods to extract knowledge and insight from structured and unstructured data. It includes data analysis, machine learning, visualization, experimentation, and related techniques for understanding phenomena and solving data-driven problems.
An interdisciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from data in various forms, both structured and unstructured, similar to data mining. Data science is a "concept to unify statistics, data analysis, machine learning, and their related methods" in order to "understand and analyze actual phenomena" with data. It employs techniques and theories drawn from many fields within the context of mathematics, statistics, information science, and computer science.
A broad grouping of mathematics, statistics, probability, computing, data visualization to extract knowledge from a heterogeneous set of data (images, sound, text, genomic data, social network links, physical measurements, etc.). The methods and tools derived from artificial intelligence are part of this family.
