Complete Coursera Big Data Specialization - University of California, San Diego

The University of California, San Diego's Big Data Specialization was developed alongside Splunk. It is another new upstart specialization which got underway this Fall, and focuses mainly on what first comes to mind when you think Big Data: the Hadoop/Spark ecosystem. It does, however, have some other topics thrown in as well, including hot topics such as graph analytics and machine learning.


The specialization contains the following courses:

▪  Introduction to Big Data
▪  Hadoop Platform and Application Framework
▪  Introduction to Big Data Analytics
▪  Machine Learning With Big Data
▪  Introduction to Graph Analytics
▪  Big Data - Capstone Project

Specialization coordinator Natasha Balac was kind enough to provide some further insight for us, answering the following questions.

▪  Introduction to Big Data

▪  Hadoop Platform and Application Framework

▪  Introduction to Big Data Analytics

▪  Machine Learning With Big Data

▪  Introduction to Graph Analytics

▪  Big Data - Capstone Project
