This is finetune version of [SimCSE: Simple Contrastive Learning of Sentence Embeddings](https://arxiv.org/abs/2104.08821) |
|
, train unsupervised on 570K stroke sentences from : stroke books, quora medical, quora's stroke and human annotates. |
|
|
|
### Extract sentence representation |
|
``` |
|
from transformers import AutoTokenizer, AutoModel |
|
tokenizer = AutoTokenizer.from_pretrained("demdecuong/stroke_simcse") |
|
model = AutoModel.from_pretrained("demdecuong/stroke_simcse") |
|
|
|
text = "What are disease related to red stroke's causes?" |
|
inputs = tokenizer(text, return_tensors='pt') |
|
outputs = model(**inputs)[1] |
|
``` |
|
### Build up embedding for database |
|
|
|
``` |
|
database = [ |
|
'What is the daily checklist for stroke returning home', |
|
'What are some tips for stroke adapt new life', |
|
'What should I consider when using nursing-home care' |
|
] |
|
|
|
embedding = torch.zeros((len(database),768)) |
|
|
|
for i in range(len(database)): |
|
inputs = tokenizer(database[i], return_tensors="pt") |
|
outputs = model(**inputs)[1] |
|
embedding[i] = outputs |
|
|
|
print(embedding.shape) |
|
``` |
|
|
|
### Result |
|
On our Poc testset , which contains pairs of matching question related to stroke from human-generated. |
