Document classification on neural networks using only positive ... https://www.researchgate.net/.../221300495_Document_classification_on_neural_net... Manevitz et al. [2] have used neural networks to classify positive documents from negative ones. They use a feed forward neural network which is first trained on a set of positive examples (labeled) and then in the test phase the network filters out the positive documents from the negative ones.
