BARTO (base-sized model)

BARTO model pre-trained on Spanish language. It was introduced in the paper Sequence-to-Sequence Spanish Pre-trained Language Models.

Model description

BARTO is a BART-based model (transformer encoder-decoder) with a bidirectional (BERT-like) encoder and an autoregressive (GPT-like) decoder. BART is pre-trained by (1) corrupting text with an arbitrary noising function and (2) learning a model to reconstruct the original text.

BARTO is particularly effective when fine-tuned for text generation (e.g. summarization, translation) but also works well for comprehension tasks (e.g. text classification, question answering).

Intended uses & limitations

You can use the raw model for text infilling. However, the model is mainly meant to be fine-tuned on a supervised dataset.

This model does not have a slow tokenizer (BartTokenizer).

How to use

Here is how to use this model in PyTorch:

from transformers import AutoTokenizer, AutoModel

tokenizer = AutoTokenizer.from_pretrained('vgaraujov/bart-base-spanish')
model = AutoModel.from_pretrained('vgaraujov/bart-base-spanish')

inputs = tokenizer("Hola amigo, bienvenido a casa.", return_tensors="pt")
outputs = model(**inputs)

last_hidden_states = outputs.last_hidden_state
