ALGORITHM OF PRUNING OF HYBRID NEURAL NETWORKS ENSEMBLE
Journal Title: Електроніка та системи управління - Year 2018, Vol 1, Issue 55
Abstract
Despite the fact that the ensemble is usually more accurate than a single network, existing ensemble techniques tend to create unreasonably large ensembles that increase the use of memory and computation costs. The ensemble's pruning solves this problem. The article analyzes the compromise between accuracy and diversity and it is proved that classifiers, which are more accurate and make more predictions in the minority group, are more important for the construction of the subensemble. A metric that takes into account accuracy and diversity is proposed to evaluate the contribution of a separate classifier that will help to allocate the required number of networks with the best results.
