## RadBERT-RoBERTa-4m

This is one variant of our Radiology-BERT models from UC San Diego and VA healthcare system. It is initialized with RoBERTa weights and further trained with 4 million radiology reports deidentified from US VA hospital. The model achieves stronger medical language understanding performance than previous medical domain models such as BioBERT, Clinical-BERT, BLUE-BERT and BioMed-RoBERTa. 

Performances are evaluated on three tasks: 
(a) abnormal sentence classification: sentence classification in radiology reports as reporting abnormal or normal findings; 
(b) report coding: Assign a diagnostic code to a given radiology report for five different coding systems; 
(c) report summarization: given the findings section of a radiology report, extractively select key sentences that summarized the findings.

It also shows superior performance on other radiology NLP tasks which are not reported in the paper.

### How to use

Here is an example of how to use this model to extract the features of a given text in PyTorch:

```python
from transformers import AutoConfig, AutoTokenizer, AutoModel
config = AutoConfig.from_pretrained('zzxslp/RadBERT-RoBERTa-4m')
tokenizer = AutoTokenizer.from_pretrained('zzxslp/RadBERT-RoBERTa-4m')
model = AutoModel.from_pretrained('zzxslp/RadBERT-RoBERTa-4m', config=config)
text = "Replace me by any medical text you'd like."
encoded_input = tokenizer(text, return_tensors='pt')
output = model(**encoded_input)
```
