## Quickstart: Emotion Detection
|
| 163 |
+
|
| 164 |
+
### Basic Inference Example
|
| 165 |
+
Classify emotions in short text inputs using the Hugging Face pipeline:
|
| 166 |
+
|
| 167 |
+
```python
|
| 168 |
+
from transformers import pipeline
|
| 169 |
+
|
| 170 |
+
# Load the fine-tuned NeuroFeel model
|
| 171 |
+
sentiment_analysis = pipeline("text-classification", model="boltuix/NeuroFeel")
|
| 172 |
+
|
| 173 |
+
# Analyze emotion
|
| 174 |
+
result = sentiment_analysis("i love you")
|
| 175 |
+
print(result)
|
| 176 |
+
```
|
| 177 |
+
|
| 178 |
+
**Output**:
|
| 179 |
+
```python
|
| 180 |
+
[{'label': 'Love', 'score': 0.8563215732574463}]
|
| 181 |
+
```
|
| 182 |
+
|
| 183 |
+
This indicates the emotion is **Love ❤️** with **85.63%** confidence.
|
| 184 |
+
|
| 185 |
+
### Extended Example with Emoji Mapping
|
| 186 |
+
Enhance the output with human-readable emotions and emojis:
|
| 187 |
+
|
| 188 |
+
```python
|
| 189 |
+
from transformers import pipeline
|
| 190 |
+
|
| 191 |
+
# Load the fine-tuned NeuroFeel model
|
| 192 |
+
sentiment_analysis = pipeline("text-classification", model="boltuix/NeuroFeel")
|
| 193 |
+
|
| 194 |
+
# Define label-to-emoji mapping

label = result["label"].capitalize()
|
| 217 |
+
emoji = label_to_emoji.get(label, "❓")
|
| 218 |
+
|
| 219 |
+
# Output
|
| 220 |
+
print(f"Text: {text}")
|
| 221 |
