Toxic Comment Classification Using RoBERTa

Overview

This project provides a toxic comment classification model based on RoBERTa (Robustly optimized BERT approach). The model is designed to classify comments as toxic or non-toxic, helping in moderating online discussions and improving community interactions.

Load the model

from transformers import pipeline

# Load the model and tokenizer
model_name = "prabhaskenche/pk-toxic-comment-classification-using-RoBERTa"
classifier = pipeline("text-classification", model=model_name)

# Example usage
text = "You're the worst person I've ever met."
result = classifier(text)
print(result)
