Dec 29, 2024 · BERT tokenization involves breaking down text into subword units, which allows the model to handle a vast vocabulary while maintaining the context of the input text. As a result, the pre-trained BERT model can be fine-tuned with just one additional output layer to create state-of-the-art models for a wide range of tasks, such as question answering and language inference, without substantial task-specific architecture modifications. . BERT_CLASS is either a tokenizer to load the vocabulary (BertTokenizer or OpenAIGPTTokenizer classes) or one of the eight BERT or three OpenAI GPT PyTorch model classes (to load the pre-trained weights): BertModel, BertForMaskedLM, BertForNextSentencePrediction, BertForPreTraining, BertForSequenceClassification, BertForTokenClassification, BertForMultipleChoice, BertForQuestionAnswering . Example: Constructs a “Fast” BERT tokenizer (backed by HuggingFace’s tokenizers library). Thanks to the Hugging-face transformers library, which has mostly all the required tokenizers for almost all popular BERT variants and this saves a lot of time for the developer.
