What is MedBERT?
MedBERT is a specialized transformer-based language model designed specifically for biomedical named entity recognition. Built upon the foundation of Bio_ClinicalBERT, this model has been extensively pre-trained on a diverse collection of biomedical datasets including N2C2, BioNLP, and CRAFT community datasets, as well as medical-related Wikipedia articles.
Implementation Details
The model implements a sophisticated pre-training approach using Google's BERT architecture. Training was conducted with carefully selected hyperparameters: batch size of 32, maximum sequence length of 256, and a learning rate of 1·10^-4. The model underwent 200,000 training steps with a duplication factor of 5 for input data masking.
