The information explosion propelled by the advent of online social media, the Internet, and global-scale communications has rendered learning from data increasingly important. At any given time around the globe, large volumes of data are generated by today’s ubiquitous communication, imaging, and mobile devices such as cell phones, surveillance cameras, medical and e-commerce platforms, as well as social networking sites. While many find this intrusive and raise legitimately “Big Brother” concerns, there is no denying that tremendous economic growth and improvement in quality of life hinge upon harnessing the potential benefits of analyzing massive data.
