+# t2p-t5-large-commonvoice
+
+*t2p-t5-large-commonvoice* is a text-to-pictograms translation model built by fine-tuning the [t5-large](https://huggingface.co/google-t5/t5-large) model on a dataset of pairs of transcriptions / pictogram token sequence (each token is linked to a pictogram image from [ARASAAC](https://arasaac.org/)).
+The model is used only for **inference**. 
+
+## Training details
+
+### Datasets
+
+The [Propicto-commonvoice dataset](https://www.ortolang.fr/market/corpora/propicto) is used, which was created from the CommmonVoice v.15.0 corpus. 
+This dataset was built with the method presented in the research paper titled ["A Multimodal French Corpus of Aligned Speech, Text, and Pictogram Sequences for Speech-to-Pictogram Machine Translation](https://aclanthology.org/2024.lrec-main.76/)" at LREC-Coling 2024. The dataset was split into training, validation, and test sets.
+| **Split** | **Number of utterances** |
+|:-----------:|:-----------------------:|
+| train | 527,390 |
+| valid | 16,124 |
+| test | 16,120 |
+
+### Parameters
+
+A full list of the parameters is available in the config.json file. This is the arguments in the training pipeline :
+
+```python
+training_args = Seq2SeqTrainingArguments(
+    output_dir="checkpoints_commonvoice/",
+    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](https://huggingface.co/spaces/evaluate-metric/sacrebleu/blob/d94719691d29f7adf7151c8b1471de579a78a280/sacrebleu.py), where we compared the reference pictogram translation with the model hypothesis.
+
+### Results
+
+Comparison to other translation models :
+| **Model** | **validation** | **test** |
+|:-----------:|:-----------------------:|:-----------------------:|
+| **t2p-t5-large-commonvoice** | 86.3 | 86.5 |
+| t2p-nmt-commonvoice | 86.0 | 82.6 | 
+| t2p-mbart-large-cc25-commonvoice | 72.3 | 72.3 |
+| t2p-nllb-200-distilled-600M-commonvoice | **87.4** | **87.6** |
+
+### Environmental Impact
+
+Fine-tuning was performed using a single Nvidia V100 GPU with 32 GB of memory which took around 30 hours in total.
+
+## Using t2p-t5-large-orféo model with HuggingFace transformers
+
+```python
+from transformers import AutoTokenizer, AutoModelForSeq2SeqLM
+
+source_lang = "fr"
+target_lang = "frp"
+max_input_length = 128
+max_target_length = 128
+
+tokenizer = AutoTokenizer.from_pretrained("Propicto/t2p-t5-large-commonvoice")
+model = AutoModelForSeq2SeqLM.from_pretrained("Propicto/t2p-t5-large-commonvoice")
+
+inputs = tokenizer("Je mange une pomme", return_tensors="pt").input_ids
+outputs = model.generate(inputs.to("cuda:0"), max_new_tokens=40, do_sample=True, top_k=30, top_p=0.95)
+pred = tokenizer.decode(outputs[0], skip_special_tokens=True)
+```
+
+## Linking the predicted sequence of tokens to the corresponding ARASAAC pictograms
+
+```python
+import pandas as pd
+
+def process_output_trad(pred):
+    return pred.split()
+
+def read_lexicon(lexicon):
+    df = pd.read_csv(lexicon, sep='\t')
+    df['keyword_no_cat'] = df['lemma'].str.split(' #').str[0].str.strip().str.replace(' ', '_')
+    return df
+
+def get_id_picto_from_predicted_lemma(df_lexicon, lemma):
+    id_picto = df_lexicon.loc[df_lexicon['keyword_no_cat'] == lemma, 'id_picto'].tolist()
+    return (id_picto[0], lemma) if id_picto else (0, lemma)
+
+lexicon = read_lexicon("lexicon.csv")
+sentence_to_map = process_output_trad(pred)
+pictogram_ids = [get_id_picto_from_predicted_lemma(lexicon, lemma) for lemma in sentence_to_map]
+```
+
+## Viewing the predicted sequence of ARASAAC pictograms in a HTML file
+
+```python
+def generate_html(ids):
+    html_content = '<html><body>'
+    for picto_id, lemma in ids:
+        if picto_id != 0:  # ignore invalid IDs
+            img_url = f"https://static.arasaac.org/pictograms/{picto_id}/{picto_id}_500.png"
+            html_content += f'''
+            <figure style="display:inline-block; margin:1px;">
+                <img src="{img_url}" alt="{lemma}" width="200" height="200" />
+                <figcaption>{lemma}</figcaption>
+            </figure>
+            '''
+    html_content += '</body></html>'
+    return html_content
+    
+html = generate_html(pictogram_ids)
+with open("pictograms.html", "w") as file:
+    file.write(html)
+```
