# poltextlab/xlm-roberta-large-pooled-czech-emotions9-v2
### Proposal 2B: German to Czech Emotion Labeling (v2)

## Model Description

This model is designed for **emotion classification** in Czech texts that have been translated from German.  
It was fine-tuned to recognize **nine emotion categories** and trained on a dataset with labeled examples.

## Labels and Their Meanings

| Label | Emotion      |
|--------|----------------|
| 0      | Anger        |
| 1      | Fear         |
| 2      | Disgust      |
| 3      | Sadness      |
| 4      | Joy          |
| 5      | None of them |
| 6      | Enthusiasm   |
| 7      | Hope         |
| 8      | Pride        |

## Evaluation Metrics

The model was evaluated using **precision, recall, f1-score, and accuracy**.

### Classification Report

| Label             | Precision | Recall | F1-score | Support |
|-------------------|-----------|--------|----------|---------|
| Anger (0)         | 0.49      | 0.61   | 0.54     | 777     |
| Fear (1)          | 0.88      | 0.71   | 0.79     | 776     |
| Disgust (2)       | 0.94      | 0.94   | 0.94     | 776     |
| Sadness (3)       | 0.84      | 0.84   | 0.84     | 775     |
| Joy (4)           | 0.82      | 0.81   | 0.81     | 736     |
| None of them (5)  | 0.67      | 0.64   | 0.66     | 1594    |
| Enthusiasm (6)    | 0.62      | 0.61   | 0.62     | 776     |
| Hope (7)          | 0.51      | 0.53   | 0.52     | 777     |
| Pride (8)         | 0.76      | 0.79   | 0.78     | 776     |

#### Overall Performance:

- **Accuracy**: 71%
- **Macro Avg**: Precision: 0.73, Recall: 0.72, F1-score: 0.72
- **Weighted Avg**: Precision: 0.72, Recall: 0.71, F1-score: 0.71

## How to Use

To use this model for text classification in Python:

```python
from transformers import pipeline

classifier = pipeline("text-classification", model="poltextlab/xlm-roberta-large-pooled-czech-emotions9-v2", use_auth_token="<HF_TOKEN>")

text = "Jsem tak ráda, že jste tady!" 
result = classifier(text)
print(result)
```
