What is Data Science?
Data science is a field of study that focuses on extracting knowledge and insights from data in various forms, either structured or unstructured, similar to Business Intelligence. Data Science is complex and has a lot of different branches and specializations, but since this article is mostly a guide for people who are interested in statistics and not so much in Business Intelligence and Data Mining, I will focus on general Data Science and not on any particular subfield. The idea behind Data Science is to take data from various sources, apply different algorithms and methods to it, and get meaningful insights from it. Data Science is a combination of statistics, computer science, mathematics, and domain knowledge (similar to Business Intelligence).
Data science is an interdisciplinary field about techniques to process data and extract knowledge from data. It is the machine learning of the 21st century. Data science is a combination of machine learning and statistics. Data science can be applied to a wide range of problems including: -Machine learning -Natural language processing -Information retrieval -Data mining -Financial prediction -Simulation -Visualization -Classification -Predictive modeling -Survey design -Information visualization -Business intelligence -Data cleaning -Combinatorial optimization -Clustering -Recommendation systems -Search engines -Database programming -Data warehousing -Data fusion -Text mining
What are the applications of Data Science?
Data Science itself is a big field. I would argue that it is a combination of many fields and disciplines. A true data scientist should know about statistics and probability, about machine learning and artificial intelligence, about database technology and database design, about data visualization and presentation, about data wrangling and cleaning. And then there are the skills that are not strictly related to the technical aspects of the job: knowledge of project management, communication skills, and so on. But Data Science is basically a HUGE field. It is hard to define it. Some people use the definition that Data Science is …….
