bert-emotion-finetuned

BERT Emotion Classifier (Fine-tuned)

Fine-tuned bert-base-uncased for 6-class emotion classification on the dair-ai/emotion dataset.

Model Description

• Author: Neeraj Gupta (@neeraj)
• Task: Text Classification (Emotion Detection)
• Base model: bert-base-uncased
• Classes: sadness, joy, love, anger, fear, surprise
• Framework: PyTorch + Hugging Face Transformers

Performance

Evaluated on the validation split after training.

Usage

from transformers import pipeline

classifier = pipeline(
    "text-classification",
    model="neeraj-miniOrange/bert-emotion-finetuned"
)

result = classifier("I am so happy today!")
print(result)
# [{'label': 'joy', 'score': 0.98...}]

Training Details

Data split: 70% train / 20% test / 10% validation (stratified)
