About Data Science

  • Data science, is an interdisciplinary field of scientific methods, processes, algorithms and systems to extract knowledge or insights from data in various forms, either structured or unstructured.
  • Data jango providing the  best data science course in Hyderabad with industry experts. 
  • The most important interdisciplinary field of all is Machine Learning (a branch of Artificial Intelligence). Simply speaking, Machine Learning is the field of study, that gives computers the ability to learn from data, without being explicitly programmed.
  • In this course we will cover all necessary concepts to make a successful Data Scientist. The concepts we cover are Descriptive Statistics, Inferential Statistics, Basic Python, Pandas, NumPy, StatsModels, Scikit-Learn, Mathematics behind Machine Learning Algorithms (Gradient Descent, SVM, Kernal SVM, etc.), error analysis and most of the accuracy measures, techniques of fine tuning the model.
  •  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.
  • 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.
  • In 2012, when Harvard Business Review called it “The Sexiest Job of the 21st Century”, the term “data science” became a buzzword. It is now often used interchangeably with earlier concepts like business analytics, business intelligence, predictive modeling, and Statistics. Even the suggestion that data science is sexy was a paraphrased reference to Dr. Hans Rosling’s 2011 BBC documentary quote, “Statistics, is now the sexiest subject around” . Nate Silver referred to data science as a sexed up term for statistics. In many cases, earlier approaches and solutions are now simply re-branded as “data science” to be more attractive, which can cause the term to become “dilute[d] beyond usefulness.” While many university programs now offer a data science degree, there exists no consensus on a definition or suitable curriculum contents. To its discredit, however, many data science and big data projects fail to deliver useful results, often as a result of poor management and utilization of resources.
