Time and Date : Friday, November 15 Place : Room 1901, 19th floor Title: Analytics over Big Data for Operational Intelligence Umeshwar Dayal Big Data Lab, Hitachi America Ltd, R&D Santa Clara, CA, USA Abstract As sensors become pervasive, and as machines and devices become increasingly interconnected (in the "Internet of Things"), huge volumes of data are being generated and captured. Big data is characterized not just by volume, but also by velocity (streaming, real-time data) and variety (structured, semi-structured, and unstructured data of many different types: logs, social media, text, files, images, video). Analytics over big data hold the promise of improving business operations by delivering actionable insights at the scale and speed required by the business. Through scenarios drawn from a number of industries, this talk will illustrate the need for a new analytics architecture and platform that goes beyond traditional business intelligence. I will describe some of the research challenges in realizing such a platform, and I will introduce the research we are starting to do in the newly formed Hitachi America Big Data Lab to address some of these challenges and to build some representative big data analytics applications.
