This episode features a discussion of “Big Data.” It’s a term that refers to the collection of very large quantities of digital information, and the use of powerful analytic tools to detect deep trends and patterns in that data that would otherwise be invisible. It has many potential uses, such as helping us to better visualize economic trends, climate trends, and demographic trends. But it also carries some serious risks, such as loss of privacy and vulnerability to manipulation and control. There are two guests. Dave Nielsen is a Technical Program Manager in the Big Data Technologies group at Intel Corporation, and is also the co-founder of CloudCamp, an organization that helps educate professionals about Cloud Computing. Bhairav Mehta is a Senior Data Scientist and Technical Program Manager at Apple, where he specializes in data analytics, data science and big data. Martin Wasserman hosts.
