Big Data or Right Data?

27 Luglio 2015
- Cappella Guinigi
Big data nowadays is a fashionable topic, independently of what people mean when they use this term. But being big is just a matter of volume, although there is no clear agreement in the size threshold. On the other hand, it is easy to capture large amounts of data using a brute force approach. So the real goal should not be big data but to ask ourselves, for a given problem, what is the right data and how much of it is needed. For some problems this would imply big data, but for the majority of the problems much less data will and is needed. In this keynote we explore the trade-offs involved and the main problems that come with big data: scalability, redundancy, bias, noise, spam, and privacy.
