Data Science Tutorial
This Data Science tutorial is written by industry experts to provide basic and advanced concepts of Data Science.
It is written in very simple language to provide maximum benefit to beginners as well as professionals. Here, you will get everything in simple and easy steps.
What is Data Science?
Data science is a field of computer science. It is a multi-disciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from structured and unstructured data.
Data science is the same concept as data mining and big data where we use the most powerful hardware, the most powerful programming systems, and the most efficient algorithms to solve problems.
Data science comprises the "concept to unify statistics, data analysis, machine learning and their related methods" in order to "understand and analyze actual phenomena" with data. It uses the techniques and theories drawn from many fields like mathematics, statistics, computer science, and information science.
Turing award winner Jim Gray imagined data science as a "fourth paradigm" of science (empirical, theoretical, computational and now data-driven) and asserted that "everything about science is changing because of the impact of information technology" and the data deluge.
Why Data Science?
Data Science is used to discover hidden patterns from the raw data. It facilitates you to extract knowledge from structured or unstructured data and makes you able to translate a business problem into a research project and then translate it back into a practical solution.
Before learning Data Science, it will be good if you have the basic knowledge of Artificial Intelligence, Big Data and Data Mining etc.
