t2p-nllb-200-distilled-600M-orfeo
t2p-nllb-200-distilled-600M-orfeo is a text-to-pictograms translation model built by fine-tuning the nllb-200-distilled-600M 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
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 |
Parameters
A full list of the parameters is available in the config.json file. This is the arguments in the training pipeline :
training_args = Seq2SeqTrainingArguments(
output_dir="checkpoints_orfeo/",
evaluation_strategy="epoch",
save_strategy="epoch",
learning_rate=2e-5,
per_device_train_batch_size=32,
per_device_eval_batch_size=32,
weight_decay=0.01,
save_total_limit=3,
num_train_epochs=40,
predict_with_generate=True,
fp16=True,
load_best_model_at_end=True
)
Evaluation
The model was evaluated with sacreBLEU, where we compared the reference pictogram translation with the model hypothesis.
Results

t2p-nllb-200-distilled-600M-orfeo | 86.3 | 86.9 |
Environmental Impact
Fine-tuning was performed using a single Nvidia V100 GPU with 32 GB of memory which took 30 hours in total.
