Fundamentals of Data Science

by Sanjeev J. Wagh, Manisha S. Bhende, Anuradha D. Thakare

Overview

Fundamentals of Data Science is designed for students, academicians and practitioners with a complete walkthrough right from the foundational groundwork required to outlining all the concepts, techniques and tools required to understand Data Science.

Data Science is an umbrella term for the non-traditional techniques and technologies that are required to collect, aggregate, process, and gain insights from massive datasets. This book offers all the processes, methodologies, various steps like data acquisition, pre-process, mining, prediction, and visualization tools for extracting insights from vast amounts of　data　by the use of various scientific methods, algorithms, and processes

Readers will learn the steps necessary to create the application with SQl, NoSQL, Python, R, Matlab, Octave and Tablue.

This book provides a stepwise approach to building solutions to data science applications right from understanding the fundamentals, performing data analytics to writing source code. All the concepts are discussed in simple English to help the community to become Data Scientist without much pre-requisite knowledge.

　

Features :

• Simple strategies for developing statistical models that analyze　data　and detect patterns, trends, and relationships in　data　sets.
• Complete roadmap to Data Science approach with dedicatedsections which includes Fundamentals, Methodology and Tools.
• Focussed approach for learning and practice various Data Science Toolswith Sample code and examples for practice.
• Information is presented in an accessible way for students, researchers and academicians and professionals.
