Doing the Impossible (Almost): A Survey of Approximation Algorithms that Make Queries Vastly Faster

Computing various quantities such as medians or the number of unique elements requires a lot of time, a lot of memory, or both. It is, however, possible to get really close to the exact answer with much less time and much less memory. Some of these algorithms are much simpler than you might expect. Ted will describe a selection of these algorithms including some not yet published results. Ted will also outline how these algorithms can be applied to practical problems like anomaly detection.
