Tīmeklis2010. gada 9. sept. · Random k-Labelsets for Multilabel Classification. Abstract: A simple yet effective multilabel learning method, called label powerset (LP), considers each distinct combination of labels that exist in the training set as a different class value of a single-label classification task. The computational efficiency and predictive … TīmeklisIt works by randomly generating K numbers and adding them to a set. If a generated number happens to already exist in the set, it places the value of a counter instead which is guaranteed to have not been seen yet. Thus it is guaranteed to run in linear time and does not require a large intermediate structure.
