Data Science Training


E school cart providing 100% Result Oriented Data Science Training in Hyderabad this course duration is 3 months. 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. 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.
