# RoBERTa for Multi-label Classification of Policy Instruments
|
| 14 |
+
|
| 15 |
+
This model fine-tunes `roberta-base` for multilabel classification of policies, targets, and themes.
|
| 16 |
+
|
| 17 |
+
## Model Details
|
| 18 |
+
- Base model: roberta-base
|
| 19 |
+
- Max length: 512
|
| 20 |
+
- Output: 47 multilabel classes (PI - Policy Instrument, TG - Target Group, TH - Theme). There are three main classes that have further sub-categories in them.
|
| 21 |
+
- Threshold: 0.25
|
| 22 |
+
|
| 23 |
+
## Intended Use
|
| 24 |
+
Classify policy documents descriptions into thematic categories.
|
| 25 |
+
|
| 26 |
+
## How to Use
|
| 27 |
+
|
| 28 |
+

|
| 54 |
+
|
| 55 |
+
# Threshold
|
| 56 |
+
binary_preds = (probs > 0.25).astype(int)
|
| 57 |
+

|
| 58 |
+
|
| 59 |
+

|
