# Model Card for Model ID

This model is a BLOOM-base adjusted to the sentiment transfer task, developed as part of a FourthBrain workshop on GenerativeAI.

## Model Details

### Model Description

This model is a BLOOM-base adjusted to the sentiment transfer task, where the objective is to reverse the sentiment polarity of a text without contradicting 
the original meaning. Positive reframing induces a complementary positive viewpoint (e.g. glass-half-full) escaping negative patterns. 
Based on the article [Ziems at. al (2022)](https://arxiv.org/abs/2204.02952).

### Input
`### Negative sentence:\n{original_text}\n\n### Reframing strategy: \n{reframing_strategy}\n\n### Reframing sentence:\n`


- **Developed by:** Telmo Correa
- **Model type:** LLM
- **Language(s) (NLP):** English
- **License:** [bigscience-bloom-rail-1.0](https://bigscience.huggingface.co/blog/the-bigscience-rail-license)
- **Finetuned from model :** [https://huggingface.co/bigscience/bloom-7b1](bigscience/bloom-1b7)

## Uses

Model trained as a proof-of-concept fine tuning of BLOOM for sentence rewriting.

### Direct Use

Model is intended to be directly used to rewrite sentences with the provided strategy.

### Out-of-Scope Use

Any uses of the model must abide by the terms of both the original BLOOM model and the Salt-NLP/positive-reframing dataset.

## Bias, Risks, and Limitations

As a fine-tuned version of BLOOM, this model carries all the biases, risks, and limitations. of its original training.

## Training Details

### Training Data

[Salt-NLP/positive-reframing](https://huggingface.co/datasets/SALT-NLP/positive_reframing)

### Training Procedure 

The baseline model [https://huggingface.co/bigscience/bloom-7b1](bigscience/bloom-1b7) was trained through 100 steps over the training split of the training data, with its prompt engineered to request explicit positive sentence reframing:

```
Below is a negative sentence, please select a reframing strategy and write the positive reframed sentence.

### Negative sentence:
NEGATIVE SENTENCE HERE

### Reframing strategy:
STRATEGY HERE

### Reframed sentence:
REFRAMED SENTENCE HERE
```


#### Training Hyperparameters

- **Training regime:** fp16 non-mixed precision, using PEFT and LoRA
