+MedBERT is a newly pre-trained transformer-based language model for biomedical named entity recognition: initialized with [Bio_ClinicalBERT](https://arxiv.org/abs/1904.03323) & pre-trained on N2C2, BioNLP, and CRAFT community datasets.
 
+## Pretraining
+
+### Data
+The `MedBERT` model was trained on N2C2, BioNLP, and CRAFT community datasets.

+| [NLP Clinical Challenges (N2C2)](https://portal.dbmi.hms.harvard.edu/projects/n2c2-nlp/) | A collection of clinical notes released in N2C2 2018 and N2C2 2022 challenges| 
+| [BioNLP](http://bionlp.sourceforge.net/index.shtml) | It contains the articles released under the BioNLP project. The articles cover multiple biomedical disciplines such as molecular biology, IE for protein and DNA modifications, biomolecular mechanisms of infectious diseases, habitats of bacteria mentioned, and bacterial molecular interactions and regulations |

+
+
+### Procedures
+The model was trained using code from [Google's BERT repository](https://github.com/google-research/bert). Model parameters were initialized with Bio_ClinicalBERT.
+
+### Hyperparameters
+We used a batch size of 32, a maximum sequence length of 128, and a learning rate of 1·10−4 for pre-training our models. The models trained for 200,000 steps. The dup factor for duplicating input data with different masks was set to 5. All other default parameters were used (specifically, masked language model probability = 0.15
+and max predictions per sequence = 22).
