Introduction to Big Data Analytics

Announcements

  • Data analytics is an emerging interdisciplinary area of machine learning, data mining, predictive analytics, text mining, forecasting and optimization, and statistics.

Big data analytics is the process of examining big data to uncover hidden patterns, unknown correlations and other useful information that can be used to make better decisions. With big data analytics, data scientists and others can analyze huge volumes of data that conventional analytics and business intelligence solutions can't touch. Consider that your organization could accumulate billions of rows of data with hundreds of millions of data combinations in multiple data stores and abundant formats. High-performance analytics is necessary to process that much data in order to figure out what's important and what isn't.

Big data is now a reality: The volume, variety and velocity of data coming into your organization continue to reach unprecedented levels. The Big Data phenomenon has emerged as a result of vast amounts of data that are becoming available across a wide range of application domains across science, business, and government.

Data may originate from many disparate sources, including:

  • scientific instruments;
  • digitally-authored media, including text, images, audio, and emails;
  • streaming data from weblogs, videos, financial/commercial transactions;
  • from ubiquitous sensing and control applications in engineered and natural systems;
  • social interactional data from social networks, twitter feeds and click streams; or
  • scientific data from large-scale surveys, and brain research.

The data can be temporal, spatial, or dynamic; structured or unstructured; and the information and knowledge derived from data can differ in representation, complexity, granularity, context, quality, provenance, reliability, and trustworthiness. This phenomenal growth means that you must not only understand big data in order to decipher the information that truly counts, but also understand the possibilities of big data analytics.

When you successfully complete this non-credit course, you will receive 18 educational contact hours (1.8 Continuing Education Units, or CEUs).
