What is ClinicalBERT?
ClinicalBERT is a specialized medical language model that builds upon the BERT architecture, specifically trained on an extensive clinical dataset comprising 1.2 billion words from diverse disease records. The model has been fine-tuned using electronic health records (EHRs) from over 3 million patient records, making it particularly adept at understanding and processing medical text.
Implementation Details
The model utilizes a masked language modeling approach, where tokens in the input text are randomly masked and the model is trained to predict the original tokens using contextual information. Training specifications include a batch size of 32, maximum sequence length of 256, and a learning rate of 5e-5.
