UCSD-VA-health/RadBERT-RoBERTa-4m

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:

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)
