\section{Research Direction}  We are using this observing mode in the first efforts to detect and image a new class of radio transient called "fast radio bursts" (FRBs; Thornton et al. 2013, Science, 341, 53). FRBs are believed to be cataclysmic events that originate half way across the universe. Their great distance has only been inferred; no direct distance measurement exists, since FRBs have only been dtected with telescopes with a poor ability to localize sources. Our commissioning of the VLA and the algorithms for millisecond transient detection has positioned us to make the first precise localization of FRBs.  I am interested in developing the concept of \emph{real-time anomaly detection} for massive data streams from radio interferometers. Real-time anomaly detection allows dynamic, data-based decisions that can change the way we collect data. In the study of radio transients, real-time detection allows us to throttle the data stream to only the brief moments of interest. This process of \emph{data triage} will be a key strategy to extracting science in data-intensive searches for "a needle in the haystack".
