# Emotion Classifier
|
| 20 |
+
|
| 21 |
+
This model classifies text into emotional categories based on the MELD (Multimodal EmotionLines Dataset) dataset. It can detect 7 emotions: anger, disgust, fear, joy, neutral, sadness, and surprise.
|
| 22 |
+
|
| 23 |
+
## Model Details
|
| 24 |
+
|
| 25 |
+
- **Model Type:** Fine-tuned transformer-based text classification model
|
| 26 |
+
- **Base Model:** RoBERTa
|
| 27 |
+
- **Training Dataset:** MELD (Multimodal EmotionLines Dataset)
|
| 28 |
+
- **Number of Parameters:** ~125M
|
| 29 |
+
- **Sequence Length:** 128 tokens
|
| 30 |
+
- **Training Approach:** Fine-tuned with cross-validation
|
| 31 |
+
|
| 32 |
+
## Intended Use
|
| 33 |
+
|
| 34 |
+
This model is designed to classify text into emotional categories. It can be used for:
|
| 35 |
+
|
| 36 |
+
- Sentiment analysis in customer feedback
|
| 37 |
+
- Emotion detection in conversations
|
| 38 |
+
- User experience research
|
| 39 |
+
- Content moderation
|
| 40 |
+
- Game development for adaptive emotional responses
|
| 41 |
+
|
| 42 |
+
## Limitations
|
| 43 |
+
|
| 44 |
+
- The model was trained on scripted dialogues from TV shows, which may not fully represent natural conversations
|
| 45 |
+
- Short texts may be harder to classify accurately
|
| 46 |
+
- Cultural and contextual nuances might not be captured
|
| 47 |
+
- The model may reflect biases present in the training data
|
| 48 |
+
|
| 49 |
+

+
- **Accuracy:** [Insert your model's accuracy]
|
| 52 |
+
- **F1 Score:** [Insert your model's F1 score]
|
| 53 |
+
- **Training Dataset Size:** ~13,000 utterances
|
| 54 |
+
|
| 55 |
+
## API Usage
|
| 56 |
+
|
| 57 |
+
```python
|
| 58 |
+
import requests
|
| 59 |
+
|
| 60 |
+
API_URL = "https://api-inference.huggingface.co/models/YourUsername/emotion-classifier-meld"
|
| 61 |
+
headers = {"Authorization": "Bearer YOUR_HF_TOKEN"}
|
| 62 |
+
|
| 63 |
+
def query(payload):
|
| 64 |
+
response = requests.post(API_URL, headers=headers, json=payload)
|
| 65 |
+
return response.json()
|
| 66 |
+
|
| 67 |
+
output = query({"inputs": "I'm feeling excited!"})
|
| 68 |
+
print(output)
|
| 69 |
+
```

+
|
| 73 |
+
This model should be used responsibly. Consider the following ethical guidelines:
|
| 74 |
+
|
| 75 |
+
- Do not use this model to manipulate people's emotions
|
| 76 |
+
- Be transparent when using emotion detection in user-facing applications
|
| 77 |
+
- Do not make high-stakes decisions based solely on this model's outputs
|
