# bert-finetuned-sst2
This model is a fine-tuned version of [bert-base-uncased](https://huggingface.co/bert-base-uncased) on an unknown dataset.
It achieves the following results on the evaluation set:
- Loss: 0.3812
- Accuracy: 0.9083
# Load model directly
```python
from transformers import AutoTokenizer, AutoModelForSequenceClassification
tokenizer = AutoTokenizer.from_pretrained("execbat/bert-finetuned-sst2")
model = AutoModelForSequenceClassification.from_pretrained("execbat/bert-finetuned-sst2")
```
## Use a pipeline as a high-level helper
```python
from transformers import pipeline
label_tags = {'LABEL_0' : "NEGATIVE",
'LABEL_1' : "POSITIVE"}
pipe = pipeline("text-classification", model="execbat/bert-finetuned-sst2")
result = pipe(["what a horrible day!", "what a wonderfull day!"])
encoded_result = [label_tags[i["label"]] for i in result]
print(encoded_result)
```
```python
['NEGATIVE', 'POSITIVE']
```
