Abstract
Methods and apparatus relating to improved SIMD (Single Instruction, Multiple Data) K-nearest-neighbors implementations are described. An embodiment provides a technique for improving SIMD implementations of the multidimensional K-Nearest-Neighbors (KNN) techniques. One embodiment replaces the non-SIMD friendly part of the KNN algorithm with a sequence of SIMD operations. For example, in order to avoid branches in the algorithm hotspot (e.g., the inner loop), SIMD operations may be used to update the list of nearest distances (and neighbors) after each iteration. Other embodiments are also disclosed and claimed.
