This model, DanteGPT, is a fine-tuned version of GPT-2 designed to generate text in the style of Dante Alighieri’s Divina Commedia. The model emulates Dante's poetic structure, including his use of tercets with a specific rhyme scheme (ABA BCB CDC) and thematic elements of his work, such as divine justice and moral reflection.

Uses

Try It Out

You can try this model interactively using the DanteGPT Space.
Simply enter a text prompt, and the model will generate verses in the style of Dante Alighieri!

Direct Use

The model is designed for generating text in the style of the Divina Commedia and can be used for literary exploration, creative writing, and educational purposes.

Downstream Use

Users may adapt the model for additional fine-tuning on similar literary texts or use it to generate other forms of poetic or stylistic writing.

Out-of-Scope Use

The model may produce inaccurate or nonsensical text when used outside its intended domain. It is not suitable for tasks requiring factual accuracy or ethical decision-making.

Bias, Risks, and Limitations

Biases

The model reflects the content and biases of the original dataset, which is a historical text. Modern ethical, cultural, and social considerations may not align with the themes or language of Dante's work.

Risks

The model may inadvertently generate offensive or inappropriate content when prompted with ambiguous or unrelated topics.
Over-reliance on this model for literary generation without proper human oversight may lead to misrepresentation of Dante’s work.

Recommendations

Users should validate generated content for coherence and appropriateness. It is recommended to use the model in combination with literary expertise to ensure quality.

How to Get Started with the Model

To use the model for text generation, run the following code snippet:

python

from transformers import GPT2LMHeadModel, GPT2Tokenizer

# Load model and tokenizer
tokenizer = GPT2Tokenizer.from_pretrained("maiurilorenzo/dante-gpt")
model = GPT2LMHeadModel.from_pretrained("maiurilorenzo/dante-gpt")

# Generate text
prompt = "Nel mezzo del cammin di nostra vita,"
input_ids = tokenizer.encode(prompt, return_tensors="pt")
output = model.generate(input_ids, max_length=100, num_beams=5, no_repeat_ngram_size=2)

print(tokenizer.decode(output[0], skip_special_tokens=True))

Training Details

Training Data

The model was fine-tuned on the Divina Commedia dataset sourced from the Hugging Face Datasets library (maiurilorenzo/divina-commedia). The dataset contains cleaned and tokenized text from the original work.

Training Procedure

Preprocessing

Removed text exceeding 1024 tokens to ensure compatibility with GPT-2's input limits.
Split the dataset into training and test subsets.
Added special tokens <|startoftext|> and <|endoftext|> to each entry for model training.

Training Hyperparameters

Training regime: FP16 mixed precision
Learning rate: 2e-5
Batch size: 16 (with gradient accumulation to simulate larger batch sizes)
Epochs: 5
Optimizer: AdamW
Scheduler: Linear warm-up with decay

Speeds, Sizes, Times

Training Time: ~1.5 hours on NVIDIA Tesla P100 (16 GB)
Model Size: ~500 MB

Evaluation

Testing Data, Factors & Metrics

Testing Data

A subset of 20 samples from the dataset was held out for testing purposes.

Factors

Evaluation focused on:

Coherence of generated text.
Thematic relevance to the Divina Commedia.

Metrics

Human Evaluation: Subjective assessment of the generated text's quality.

Results

Human Evaluation: 75% accuracy in replicating Dante’s style (based on thematic and stylistic criteria).

Summary

The model successfully generates stylistically accurate text that aligns with the poetic form and thematic elements of Dante’s work. Inconsistencies in rhyme and coherence may occur in longer outputs.

Environmental Impact

Carbon emissions can be estimated using the Machine Learning Impact calculator presented in Lacoste et al. (2019).
