SciFive

SciFive provided a Text-Text framework for biomedical language and natural language in NLP. Under the T5's framework and desrbibed in the paper SciFive: a text-to-text transformer model for biomedical literature, SciFive achieve state-of-the-art and competitive results on multiple biomedical-natural language tasks.

🎉 UPDATE Jan 2023

We are migrating SciFive into BioT5X: Pretrained T5X Transformer for Biomedical Text Generation and Classification that use T5X and Flaxformer

Google Cloud Storage

Our base Google Cloud Storage URI is at gs://scifive

As described in our paper, we make public 6 version of SciFive, each one has been benchmarked to achieve state-of-the-art on different biomedical task. They are all available on our Google Cloud bucket, we are working on release the models on HuggingFace also.

Instruction on access Cloud Storage from the command line with python library gsutil is described here

gsutil URI for 6 SciFive models:

The following table contains pretrained SciFive checkpoints.

• {size} is either base or large

gsutil URI for Pretrain data:

• Pubmed: gs://scifive/pretrain/pubmed

Example

Below, we give an example of how to use SciFive on Huggingface to generate MedNLI outputs. We also publish our SciFive finetuned on MedNLI for reproducing experiments.

from transformers import AutoTokenizer, AutoModelForSeq2SeqLM

tokenizer = AutoTokenizer.from_pretrained("razent/SciFive-large-Pubmed_PMC-MedNLI")  
model = AutoModelForSeq2SeqLM.from_pretrained("razent/SciFive-large-Pubmed_PMC-MedNLI")
model.cuda()

sent_1 = "In the ED, initial VS revealed T 98.9, HR 73, BP 121/90, RR 15, O2 sat 98% on RA."
sent_2 = "The patient is hemodynamically stable"
text =  f"mednli: sentence1: {sent_1} sentence2: {sent_2}"

encoding = tokenizer.encode_plus(text, padding='max_length', max_length=256, return_tensors="pt")
input_ids, attention_masks = encoding["input_ids"].to("cuda"), encoding["attention_mask"].to("cuda")

outputs = model.generate(
    input_ids=input_ids, attention_mask=attention_masks,
    max_length=8,
    early_stopping=True
)

for output in outputs:
    line = tokenizer.decode(output, skip_special_tokens=True, clean_up_tokenization_spaces=True)
    print(line)
