# 🎯 Sentinel Quantization
|
| 2 |
+
|
| 3 |
+
## Overview
|
| 4 |
+
|
| 5 |
+
**Sentinel Quantization** — Model quantization using **dynamical constants** from the Sentinel function iteration.
|
| 6 |
+
|
| 7 |
+
## Key Innovation
|
| 8 |
+
|
| 9 |
+
Use proven dynamical properties of F(z) = Σ zⁿ/nⁿ as quantization parameters:
|
| 10 |
+
|
| 11 |
+
- **Zero-point**: C₁ = −0.007994021805953 (attracting fixed point)
|
| 12 |
+
- **Scale factor**: 1/e = 0.367879441171442 (Gradient Axiom limit)
|
| 13 |
+
|
| 14 |
+
```python
|
| 15 |
+
q = round((w - C₁) / (max|w| · 1/e))
|
| 16 |
+
```
|
| 17 |
+
|
| 18 |
+
## Verified Results
|

+
|
| 20 |
+
| Property | Standard INT8 | Sentinel INT8 |
|
| 21 |
+
|----------|--------------|--------------|
|
| 22 |
+
| Zero-point | Manual (0 or learned) | **C₁ = −0.007994…** |
|
| 23 |
+
| Scale | Empirical (max/255) | **max·(1/e)** |
|
| 24 |
+
| Theoretical basis | None | **Dynamical constants** |
|
| 25 |
+
| Compression | 4.0× | **4.0×** |
|
| 26 |
+
| Dequantization error | ~0.01 | **0.0044** |
