🚫 Toxic Comment Classification using BERT

This project classifies toxic as well as sarcastic comments using a fine-tuned BERT model with an accuracy of over 95%. It integrates unlabeled data from the Jigsaw Toxic Comment Classification Challenge and utilizes a custom API wrapper named isomina for training orchestration and evaluation.

🧠 Model

• Base: bert-base-uncased
• Fine-tuned on labeled and pseudo-labeled Jigsaw dataset
• Multi-label classification (toxic, severe_toxic, obscene, threat, insult, identity_hate)
• Trained using custom isomina API wrapper for streamlined experimentation and deployment

---

📊 Output Examples

| Visualization of Predictions |

• In output2.png, we see that a sarcastic message was correctly identified.
