METHOD FOR REFINING TRAINING DATA SET FOR AUDIO CLASSIFIERS AND METHOD FOR CLASSIFYING DATA

摘要

A method refines labeled training data audio classification of multimedia content. A first set of audio classifiers is trained using labeled audio frames of a training data set having labels corresponding to a set of audio features. Each audio frame of the labeled training data set is classified using the first set of audio classifiers to produce a refined training data set. A second set of audio classifiers is obtained using audio frames of the refined training data set, and highlights are extracted from unlabeled audio frames using the second set of audio classifiers.
