Acceleration Method for Extracting Critical Features with Hash-based group and recording medium thereof

摘要

The present invention relates to a method for accelerating extraction of a core element using a hash based group. The method for accelerating the extraction of the core element according to the present invention comprises: a first step of grouping original data based on hash; a second step of performing a random pruning operation with respect to the grouped data; and a third step of applying a principal component analysis algorithm to the randomly pruned data and processing the same. The present invention can largely reduce calculation time and enhance accuracy of a result when the main component analysis algorithm is performed.
