| NeurIPS & IEEE Transactions Publication-Grade Empirical & Statistical Evaluation Pipeline. | |
| Performs rigorous statistical hypothesis testing across all 6 frontier research modules: | |
| 1. Self-Speculative Decoding vs Standard Autoregressive Baseline | |
| 2. Semantic Anchor KV-Cache vs Full FP16 Baseline | |
| 3. Fused Block-Tiled TT Contraction vs Unfused Multi-Core Einsum | |
| 4. LinUCB Contextual Bandit Policy vs Fixed-Rank Baseline | |
| 5. Salience-Gated Adaptive Vision Projector vs Uniform Rank Baseline | |
| 6. 2D Dynamic Compute Grid Pareto Hypervolume | |
| Calculates for all comparisons: | |
| - Mean and Standard Deviation | |
| - 95% Bootstrap Confidence Intervals (B=1,000 resamples) | |
| - Two-Tailed Paired Student's t-test (t-statistic, p-value) | |
| - Non-parametric Wilcoxon Signed-Rank Test (W-statistic, p-value) | |
| - Standardized Effect Size (Cohen's d) | |
| Outputs: | |
| - results/raw/neurips_statistical_evaluation.json | |
| - Console statistical significance table | |
