t2p-mbart-large-cc25-orfeo

t2p-mbart-large-cc25-orfeo is a text-to-pictograms translation model built by fine-tuning the mbart-large-cc25 model on a dataset of pairs of transcriptions / pictogram token sequence (each token is linked to a pictogram image from ARASAAC). The model is used only for inference.

Training details

The model was trained with Fairseq.

Datasets

The Propicto-orféo dataset is used, which was created from the CEFC-Orféo corpus. This dataset was presented in the research paper titled "A Multimodal French Corpus of Aligned Speech, Text, and Pictogram Sequences for Speech-to-Pictogram Machine Translation" at LREC-Coling 2024. The dataset was split into training, validation, and test sets.

Split	Number of utterances
train	231,374
valid	28,796
test	29,009

Evaluation

The model was evaluated with sacreBLEU, where we compared the reference pictogram translation with the model hypothesis.
