## Dataset 1: DOE Full Factorial Design
|
||
|
||

|
||
- **Configurations**: 128 (2^7 binary combinations of feedback loops L1-L7)
|
||
- **Replicates per config**: 300
|
||
- **Workload**: Fixed Forth benchmark (4,501 words executed)
|
||
|
||
### Performance Results
|
||
|
||
| Metric | Value |
|
||
|--------|-------|
|
||
| Best config | #35 @ 31.59 ms/word |
|
||
| Worst config | #124 @ 59.48 ms/word |
|
||
| Performance spread | 88.3% slower (worst vs best) |
|
||
| Median performance | 40.77 ms/word |
|
||
| CV range | 13.77% - 26.90% |
|
||
|
||
### Configuration Analysis
|
||
|
||
**Best Configuration (#35 = 0100011 binary)**:
|
||
```
|
||
L1_heat: OFF
|
||
L2_window: ON ✓
|
||
L3_decay: OFF
|
||
L4_pipeline: OFF
|
||
L5_win_inf: OFF
|
||
L6_decay_inf: ON ✓
|
||
L7_heartrate: ON ✓
|
||
|
||
Performance: 31.59 ms ± 4.78 ms (CV: 15.13%)
|
||
Cache hit rate: 0.00%
|
||
```
|
||
|
||
**Worst Configuration (#124 = 1111100 binary)**:
|
||
```
|
||
L1_heat: ON ✓
|
||
L2_window: ON ✓
|
||
L3_decay: ON ✓
|
||
L4_pipeline: ON ✓
|
||
L5_win_inf: ON ✓
|
||
L6_decay_inf: OFF
|
||
L7_heartrate: OFF
|
||
|
||
Performance: 59.48 ms ± 10.80 ms (CV: 18.15%)
|
||
Cache hit rate: 31.24%
|
||
```
|
||
|
||
**Key Insight**: The worst configuration has 5/7 loops enabled with high cache hit rate (31%), yet performs 88% slower. This demonstrates that "more adaptation" ≠ "better performance" - coordination matters.

## Dataset 4: Shape-Invariant Waveform Validation
|
||
|
||
### Overview
|
||
- **Total runs**: 1,200
|
||
- **Waveform types**: 4 (baseline, damped_sine, square_wave, triangle)
|
||
- **Replicates per waveform**: 300
|
||
- **Configuration**: Fixed (100101 - the runoff winner)
|
||
|
||
### Results
|
||
|
||
| Waveform | Mean (ms) | Std (ms) | CV (%) |
|
||
|----------|-----------|----------|--------|
|
||
| baseline | 59.01 | 1.11 | **1.89** |
|
||
| triangle | 58.93 | 1.09 | **1.84** |
|
||
| square_wave | 59.16 | 1.30 | **2.19** |
|
||
| damped_sine | 59.02 | 1.44 | **2.44** |
|
||
|
||
**Shape-Invariance Metrics**:
|
||
- CV range: 1.84% - 2.44%
|
||
- CV spread: **0.60%** (exceptionally tight!)
|
||
- Mean performance ratio: 1.0039x (max/min)
|
||
- Shape-invariant: **✓ YES** (all waveforms within 0.6% CV variation)
|
||
|
||
**Key Insight**: SSM maintains remarkably consistent performance (CV ~2%) across diverse waveform shapes - a critical property for unpredictable real-world workloads.
|
||

|
||
|
||
## Attractor Surface Analysis
|
||
|
||
The attractor surface visualization plots the 3D relationship between:
|
||
- **X-axis**: Configuration ID (0-127)
|
||
- **Y-axis**: Mean rolling window size (3900-4300)
|
||
- **Z-axis**: Coefficient of variation (0.14-0.26)
|
||
|
||
### Key Observations
|
||
|
||
1. **Dense Clustering**: Majority of configurations converge to CV ~0.16-0.20 region
|
||
2. **Stable Attractor**: Basin centered around optimal performance zone
|
||
3. **Outliers**: Configurations with CV >0.22 are rare and unstable
|
||
4. **Robustness**: 10% variation in window size still maintains convergence
|
||
|
||
This geometric structure provides the foundation for formal verification of convergence properties using Lyapunov stability analysis.

|
||
|
||
## Critical Insights for Patent & DARPA
|
||
|
||
### 1. Problem Severity (Figure 1 evidence)
|
||
- Static configuration choice has **88% performance impact**
|
||
- No way to predict optimal config without exhaustive testing
|
||
- Manual tuning is impractical (128 configs × 300 reps = 38,400 runs)
|
||
|
||
### 2. SSM Solution Effectiveness
|
||
- L8 autonomously selected Config #55 (rank #6/128, only 1% slower than optimal)
|
||
- **Zero manual tuning** required
|
||
- Consistent selection across all 5 workload families
|
||
|
||
### 3. Shape-Invariance Achievement
|
||
- CV variation <0.6% across all waveform types
|
||
- Proves system maintains predictable behavior despite input diversity
|
||
- Critical for mission-critical/safety-critical deployment
|
||
|
||
### 4. Self-Organization Evidence
|
||
- Attractor basin visualization shows geometric convergence
|
||
- System finds stable operating point from arbitrary initial conditions
|
||
- Supports Lyapunov stability claims for formal verification
|
||
|
||
### 5. Industrial Applicability
|
||
- ~52,000 experimental runs demonstrate robustness
|
||
- Real implementation (StarForth VM) not simulation
|
||
- Reproducible results across 5-day collection period
|
||
