REDUCED MISS RATE IN SOUND TO TEXT CONVERSION USING BANACH SPACES

Abstract:

A computer-implemented method includes: comparing features extracted from a first document that include a sound to features extracted from acoustic files related to the sound; designating the sound in a document of the plurality of documents as a true; designating the sound in the first document as a false negative; generating a first sound vector for the sound in the first document in response to the sound in the first document being designated a false negative; generating a sound vector for each of the documents designated as a true positive; creating a centroid vector for the sound vectors of the documents designated as a true positive; and redesignating the sound in the first document from a false negative to a true positive in response to the first sound vector and the centroid vector being a Banach space.
