CatastroBERT

CatastroBERT a model for Extreme weather events detection in French text

This model aims to facilitate the detection of paragraphs or articles relevant to extreme weather events in French text. It is based on the camembert-base model and was trained on manually annotated data (articles summaries) from the Gazette de Lausanne archives collected by impresso

Model Description

• Developed by: Lucas Nicolas

• Language(s) (NLP): French

• Finetuned from model : camembert-base (RoBERTa Checkpoint)

Usage

In Transformers

from transformers import AutoTokenizer, AutoModelForSequenceClassification
import torch


model_name = "epfl-dhlab/CatastroBERT"
tokenizer = AutoTokenizer.from_pretrained(model_name)
model = AutoModelForSequenceClassification(model_name)

def predict(text):
    # Prepare the text data
    inputs = tokenizer.encode_plus(
        text,
        None,
        add_special_tokens=True,
        return_token_type_ids=True,
        padding=True,
        max_length=512,
        truncation=True,
        return_tensors='pt'
    )

    ids = inputs['input_ids'].to('cuda' if torch.cuda.is_available() else 'cpu')
    mask = inputs['attention_mask'].to('cuda' if torch.cuda.is_available() else 'cpu')

    # Get predictions
    with torch.no_grad():
        outputs = model(ids, mask)
        logits = outputs.logits

    # Apply sigmoid function to get probabilities
    probs = torch.sigmoid(logits).cpu().numpy()

    # Return the probability of the class (1)
    return probs[0][0]

#example usage 
text = "Un violent ouragan du sud-ouest est passé cette nuit sur Lausanne."
print(f"Prediction: {predict(text)}")
