In recent times, large high-dimensional datasets have become ubiquitous. Video and image repositories, financial, and sensor data are just a few examples of such datasets in practice. Many applications that use such datasets require the retrieval of data items similar to a given query item, or the Nearest Neighbors (NN or k-NN) of a given item. Another common query is the retrieval of multiple sets of nearest neighbors, i.e., multi k-NN, for different query items on the same data.
