“Issues And Challenges In Mining Large Data Sets”

By Dr. Fatos Xhafa, Technical University Of Catalonia, Spain


Big Data is an emerging disruptive technology with a large potential for causing changes in business practices, markets and commerce, and consequently in consumers’ lives. Big Data is seen as a new valuable asset for enterprises (also coined as “new oil”). However, the challenge is how to turn data into value, namely, how to extract knowledge from Big Data and incorporate it into business workflows and decision support systems and improve business processes, increase efficiency, increase consumer satisfaction, reduce costs, etc.

In this talk we will discuss the main drivers behind big data and the life cycle of the big data along several  real life use cases from businesses. Several techniques about building knowledge and intelligence from Big Data willbe discusssed. Then, we will focus on the challenges of various implementation approaches and issuess of mining large data sets such as scalability and memory issues faced. We will conclude the talk with some lessons learned and challenges on the Big data fundamental shift: how to efficiently process, mine and analyse large data sets!
