There are many ways in which the law can be classified. In the next post, we will delve further into the next new phenomenon in NLP space - Transfer Learning with BERT and ULMFit. BERT stands for Bidirectional Encoder Representations from Transformers. In order to support easier interpretation and problem detection, the report integrates numerical scores with a color-coded heatmap. For the best performance, use the smallest size that does not result in your text being outrageously cut (this is difficult to estimate). The second central method for the DatasetReader is the text_to_instance method. We recommend that users use pre-trained student models whenever possible to fully take advantage of large-scale pre-training. We apply BERT, a popular Transformer model, on fake news detection using Pytorch.
