More is less: Signal processing and the data deluge

The data deluge is changing the operating environment of many sensing systems from data-poor to data-rich––so data-rich that we are in jeopardy of being overwhelmed. Managing and exploiting the data deluge require a reinvention of sensor system design and signal processing theory. The potential pay-offs are huge, as the resulting sensor systems will enable radically new information technologies and powerful new tools for scientific discovery.
