# RuBERT for NLI (natural language inference) |
|
|
|
This is the [DeepPavlov/rubert-base-cased](https://huggingface.co./DeepPavlov/rubert-base-cased) fine-tuned to predict the logical relationship between two short texts: entailment, contradiction, or neutral. |
|
|
|
## Usage |
|
How to run the model for NLI: |
|
```python |
|
# !pip install transformers sentencepiece --quiet |
|
import torch |
|
from transformers import AutoTokenizer, AutoModelForSequenceClassification |
|
|
|
model_checkpoint = 'cointegrated/rubert-base-cased-nli-threeway' |
|
tokenizer = AutoTokenizer.from_pretrained(model_checkpoint) |
|
model = AutoModelForSequenceClassification.from_pretrained(model_checkpoint) |
|
if torch.cuda.is_available(): |
|
model.cuda() |
|
|
|
text1 = 'Сократ - человек, а все люди смертны.' |
|
text2 = 'Сократ никогда не умрёт.' |
|
with torch.inference_mode(): |
|
out = model(**tokenizer(text1, text2, return_tensors='pt').to(model.device)) |
|
proba = torch.softmax(out.logits, -1).cpu().numpy()[0] |
|
print({v: proba[k] for k, v in model.config.id2label.items()}) |
|
# {'entailment': 0.009525929, 'contradiction': 0.9332064, 'neutral': 0.05726764} |
|
``` |
|
|
|
You can also use this model for zero-shot short text classification (by labels only), e.g. for sentiment analysis: |
|
|
|
```python |
|
def predict_zero_shot(text, label_texts, model, tokenizer, label='entailment', normalize=True): |
|
label_texts |
|
tokens = tokenizer([text] * len(label_texts), label_texts, truncation=True, return_tensors='pt', padding=True) |
|
with torch.inference_mode(): |
|
result = torch.softmax(model(**tokens.to(model.device)).logits, -1) |
|
proba = result[:, model.config.label2id[label]].cpu().numpy() |
|
if normalize: |
|
proba /= sum(proba) |
|
return proba |
|
|
|
classes = ['Я доволен', 'Я недоволен'] |
|
predict_zero_shot('Какая гадость эта ваша заливная рыба!', classes, model, tokenizer) |
|
# array([0.05609814, 0.9439019 ], dtype=float32) |
|
predict_zero_shot('Какая вкусная эта ваша заливная рыба!', classes, model, tokenizer) |
|
# array([0.9059292 , 0.09407079], dtype=float32) |
|
``` |
|
|
|
Alternatively, you can use [Huggingface pipelines](https://huggingface.co./transformers/main_classes/pipelines.html) for inference. |
|
|
|
