## Usage
|
| 68 |
+
|
| 69 |
+
### Using Transformers
|
| 70 |
+
|
| 71 |
+
```python
|
| 72 |
+
from transformers import pipeline
|
| 73 |
+
|
| 74 |
+
# Using the pipeline
|
| 75 |
+
classifier = pipeline("text-classification", model="your-username/emotion-distilbert-finetuned")
|
| 76 |
+
result = classifier("I feel great today!")
|
| 77 |
+
print(result)
|
| 78 |
+
# Output: [{'label': 'joy', 'score': 0.9876}]
|
| 79 |
+
```
|
| 80 |
+
|
| 81 |
+
### Direct Usage
|
| 82 |
+
|
| 83 |
+
```python
|
| 84 |
+
from transformers import AutoTokenizer, AutoModelForSequenceClassification
|
| 85 |
+
import torch
|
| 86 |
+
|
| 87 |
+
# Load model and tokenizer
|
| 88 |
+
tokenizer = AutoTokenizer.from_pretrained("your-username/emotion-distilbert-finetuned")
|
| 89 |
+
model = AutoModelForSequenceClassification.from_pretrained("your-username/emotion-distilbert-finetuned")
|
| 90 |
+
|
| 91 |
+
# Emotion labels
|
| 92 |
+
emotion_labels = {
|
| 93 |
+
0: "sadness",
|
| 94 |
+
1: "joy",
|
| 95 |
+
2: "love",
|
| 96 |
+
3: "anger",
|
| 97 |
+
4: "fear",
|
| 98 |
+
5: "surprise"
|
| 99 |
+
}
|
| 100 |
+
|
| 101 |
+
# Classify emotion
|
| 102 |
+
text = "I feel great today!"
|
| 103 |
+
inputs = tokenizer(text, return_tensors="pt", truncation=True, padding=True)
|
| 104 |
+
|
| 105 |
+
with torch.no_grad():
|
| 106 |
+
outputs = model(**inputs)
|
| 107 |
+
predicted_class = torch.argmax(outputs.logits, dim=1).item()
|

print(f"Predicted emotion: {emotion_labels[predicted_class]}")
|
| 110 |
+
```

| 116 |
+
with torch.no_grad():
|
| 117 |
+
outputs = model(**inputs)
|
| 118 |
+
probabilities = torch.softmax(outputs.logits, dim=1).squeeze()
|
| 119 |
+
|
| 120 |
+
for i, prob in enumerate(probabilities):
|
| 121 |
+
print(f"{emotion_labels[i]}: {prob:.4f}")
|
| 122 |
+

+
## Performance Notes
|
| 143 |
+
|
| 144 |
+
- Model was trained on a dataset balanced across emotion categories
|
| 145 |
+
- Best model checkpoint was selected based on validation F1 score
|
| 146 |
+
- Model performs well on various text lengths and domains
|
| 147 |
+
- May require domain adaptation for very specific use cases
|
| 148 |
+
|
| 149 |
+
## Limitations
|
| 150 |
+
|
| 151 |
+
- Trained primarily on English text
|
| 152 |
+
- May not generalize well to other languages
|
| 153 |
+
- Performance may vary across different text domains
|
| 154 |
+
- Model predictions should be used with appropriate confidence thresholds
