# T5-base fine-tuned for Sentiment Analysis 👍👎


[Google's T5](https://ai.googleblog.com/2020/02/exploring-transfer-learning-with-t5.html) base fine-tuned on [SST-2](https://huggingface.co/datasets/st2) dataset for **Sentiment Analysis** downstream task.

## Details of T5

The **T5** model was presented in [Exploring the Limits of Transfer Learning with a Unified Text-to-Text Transformer](https://arxiv.org/pdf/1910.10683.pdf) by *Colin Raffel, Noam Shazeer, Adam Roberts, Katherine Lee, Sharan Narang, Michael Matena, Yanqi Zhou, Wei Li, Peter J. Liu*

## Model fine-tuning 🏋️‍

The model has been finetuned for 10 epochs on standard hyperparameters

## Model in Action 🚀

```python
from transformers import T5Tokenizer, T5ForConditionalGeneration

tokenizer = T5Tokenizer.from_pretrained("t5-finetune-sst2")
model = T5ForConditionalGeneration.from_pretrained("t5-finetune-sst2")

def get_sentiment(text):

    inputs = tokenizer("sentiment: " + text, max_length=128, truncation=True, return_tensors="pt").input_ids
    preds = model.generate(inputs)
    decoded_preds = tokenizer.batch_decode(sequences=preds, skip_special_tokens=True)

    return decoded_preds

get_sentiment("This movie is awesome")

# labels are 'p' for 'positive' and 'n' for 'negative'
# Output: ['p']
```
