The stock market,the social media giants like Facebook,twitter,log files etc. Most literature reviews describe the learning process of discovering and documenting all that is already known about a particular topic before attempting to add to it. This tutorial is designed for Computer Science graduates as well as Software Professionals who are willing to learn data science in simple and easy steps using Python as a programming language. generate this kind of so called structured or unstructured data ,which is coined as the big data. What does this mean in comparison to data scientist? If not properly done, dirty data can obfuscate the 'truth' hidden in the data set and completely mislead results. Businesses use data scientists to source, manage, and analyze large amounts of unstructured data. For example, collaborative filtering is a type of recommendations algorithm with elements related to both supervised and unsupervised learning. It involves developing methods of recording, storing, and analyzing data to effectively extract useful information. Ultimately, the value doesn't come from data, math, and tech itself. Much to learn by mining it. In simple words, a Data Scientist is one who practices the art of Data Science.
