# poem-gen-spanish-t5-small

This model is a fine-tuned version of [flax-community/spanish-t5-small](https://huggingface.co/flax-community/spanish-t5-small) on the [Spanish Poetry Dataset](https://www.kaggle.com/andreamorgar/spanish-poetry-dataset/version/1) dataset.

The model was created during the [First Spanish Hackathon](https://somosnlp.org/hackathon) organized by [Somos NLP](https://somosnlp.org/).

The team who participated was composed by:

- 🇨🇺 [Alberto Carmona Barthelemy](https://huggingface.co/milyiyo)
- 🇨🇴 [Jorge Henao](https://huggingface.co/jorge-henao)
- 🇪🇸 [Andrea Morales Garzón](https://huggingface.co/andreamorgar)
- 🇮🇳 [Drishti Sharma](https://huggingface.co/DrishtiSharma)

It achieves the following results on the evaluation set:
- Loss: 2.8707
- Perplexity: 17.65


## Model description

The model was trained to generate spanish poems attending to some parameters like style, sentiment, words to include and starting phrase.

Example:

```
poema:
  estilo: Pablo Neruda &&
  sentimiento: positivo &&
  palabras: cielo, luna, mar &&
  texto: Todos fueron a verle pasar
```

### How to use

You can use this model directly with a pipeline for masked language modeling:

```python
from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
model_name = 'hackathon-pln-es/poem-gen-spanish-t5-small'
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSeq2SeqLM.from_pretrained(model_name)

author, sentiment, word, start_text = 'Pablo Neruda', 'positivo', 'cielo', 'Todos fueron a la plaza'
input_text = f"""poema: estilo: {author} && sentimiento: {sentiment} && palabras: {word} && texto: {start_text} """
inputs = tokenizer(input_text, return_tensors="pt")

outputs = model.generate(inputs["input_ids"],
                         do_sample = True,
                         max_length = 30,
                         repetition_penalty = 20.0,
                         top_k = 50,
                         top_p = 0.92)
detok_outputs = [tokenizer.decode(x, skip_special_tokens=True) for x in outputs]
res = detok_outputs[0]
```

## Training and evaluation data

The original [dataset](https://www.kaggle.com/andreamorgar/spanish-poetry-dataset/version/1) has the columns `author`, `content` and `title`.
For each poem we generate new examples:
- content: *line_i* , generated: *line_i+1*
- content: *concatenate(line_i, line_i+1)* , generated: *line_i+2*
- content: *concatenate(line_i, line_i+1, line_i+2)* , generated: *line_i+3*

The resulting dataset has the columns `author`, `content`, `title` and `generated`.

For each example we compute the sentiment of the generated column and the nouns. In the case of sentiment, we used the model `mrm8488/electricidad-small-finetuned-restaurant-sentiment-analysis` and for nouns extraction we used spaCy.
