Model Details

• Architecture: google/electra-small-discriminator
• Task: Text emotion classification (6 classes)
• Dataset: dair-ai/emotion
• Classes: sadness, joy, love, anger, fear, surprise

Training

• Platform: Kaggle GPU T4
• Epochs: 4
• Batch size: 16
• Learning rate: 5e-5
• Test Accuracy: 92.65%
• Test F1: 92.69%
• Model Size: 54.2 MB

Why This Won

Higher accuracy, lower loss, 2.5× smaller than v1 (MiniLM), and faster inference. The RTD pretraining objective produces more efficient representations.
