Mining negative patterns
WebFor this reason, regex-based classifiers suffer by having low recall. That is, it often misses items that should be classified as positive. In this paper, we provide a neural network solution to this problem by identifying a "negative reversion set," in which false negative items occur much more frequently than in the data set as a whole. Thus, the
