# Long-Context Attention Regressor (Composite)
|
| 13 |
+
|
| 14 |
+
Predicts a **composite score** combining multiple attention metrics to identify text that benefits from long context.
|
| 15 |
+
|
| 16 |
+
## Usage
|
| 17 |
+
|
| 18 |
+
```python
|
| 19 |
+
from transformers import AutoTokenizer, AutoModelForSequenceClassification
|
| 20 |
+
import torch
|
| 21 |
+
|
| 22 |
+
model = AutoModelForSequenceClassification.from_pretrained("KevinDavidHayes/regressor-composite")
|
| 23 |
+
tokenizer = AutoTokenizer.from_pretrained("KevinDavidHayes/regressor-composite")
|
| 24 |
+
|
| 25 |
+
text = "Your text here..."
|
| 26 |
+
inputs = tokenizer(text, return_tensors="pt", truncation=True, max_length=8192)
|
| 27 |
+
|
| 28 |
+
with torch.no_grad():
|
| 29 |
+
score = model(**inputs).logits.item()
|
| 30 |
+
|
| 31 |
+
# Higher score = text benefits more from long-range attention
|
| 32 |
+
```
|
| 33 |
+
|
| 34 |
+
## Training
|
| 35 |
+
|
| 36 |
+
- **Base model**: ModernBERT-base (8K context)
|
| 37 |
+
- **Target**: Weighted combination: 0.2 * mean_distance + 0.4 * inv_local_ratio + 0.4 * entropy
|
| 38 |
+
- **Labels**: Generated using Qwen2.5-7B-Instruct attention analysis at layer 14
|
| 39 |
+
|
| 40 |
+
## Why Composite?
|
| 41 |
+
|
| 42 |
+
Cross-context correlation analysis showed:
|
| 43 |
+
- mean_distance: r=0.71 (4K→32K)
|
| 44 |
+
- local_ratio: r=0.92
|
| 45 |
+
- entropy: r=0.92
|
| 46 |
+
|
| 47 |
+
The composite weights metrics by their cross-context stability.
