# Stance-Tw
This model is a fine-tuned version of [j-hartmann/sentiment-roberta-large-english-3-classes](https://huggingface.co/j-hartmann/sentiment-roberta-large-english-3-classes) to predict 3 categories of author stance (attack, support, neutral) towards an entity mentioned in the text.
- training procedure available in [Colab notebook](https://colab.research.google.com/drive/12DsO5dNaQI3kFO7ohOHZn4EWNewFy2jm?usp=sharing)
- result of a collaboration with [Laboratory of The New Ethos](https://newethos.org/laboratory/)
```
# Model usage
from transformers import pipeline
model_path = "eevvgg/Stance-Tw"
cls_task = pipeline(task = "text-classification", model = model_path, tokenizer = model_path)#, device=0
sequence = ['his rambling has no clear ideas behind it',
'That has nothing to do with medical care',
"Turns around and shows how qualified she is because of her political career.",
'She has very little to gain by speaking too much']
result = cls_task(sequence)
labels = [i['label'] for i in result]
labels # ['attack', 'neutral', 'support', 'attack']
```
## Intended uses & limitations
Model suited for classification of stance in short text. Fine-tuned on a manually-annotated corpus of size 3.2k.
## Training procedure
### Training hyperparameters
The following hyperparameters were used during training:
- optimizer: {'name': 'Adam', 'learning_rate': 4e-5, 'decay': 0.01}
Trained for 3 epochs, mini-batch size of 8.
- loss: 0.719
## Evaluation data
It achieves the following results on the evaluation set:
- macro f1-score: 0.758
- weighted f1-score: 0.762
- accuracy: 0.762
