A NonMetric Space Library ('NMSLIB' <https://github.com/nmslib/nmslib>) wrapper, which according to the authors "is an efficient crossplatform similarity search library and a toolkit for evaluation of similarity search methods. The goal of the 'NMSLIB' <https://github.com/searchivarius/nmslib> Library is to create an effective and comprehensive toolkit for searching in generic nonmetric spaces. Being comprehensive is important, because no single method is likely to be sufficient in all cases. Also note that exact solutions are hardly efficient in high dimensions and/or nonmetric spaces. Hence, the main focus is on approximate methods". The wrapper also includes Approximate Kernel kNearestNeighbor functions based on the 'NMSLIB' <https://github.com/searchivarius/nmslib> 'Python' Library.
