TY - T1 - Efficient Autotuning of Hyperparameters in Approximate Nearest Neighbor Search SN - / UR - http://hdl.handle.net/10138/303722 T3 - Lecture Notes in Artificial Intelligence A1 - Jääsaari, Elias; Hyvönen, Ville; Roos, Teemu A2 - PB - Springer Y1 - 2019 LA - eng AB - Approximate nearest neighbor algorithms are used to speed up nearest neighbor search in a wide array of applications. However, current indexing methods feature several hyperparameters that need to be tuned to reach an acceptable accuracy–speed trade-off. A grid search in the parameter space is often impractically slow due to a time-consuming index-building procedure. Therefore, we propose an algorithm for automatically tuning the hyperparameters of indexing methods based on randomized space-part...
