Comprehensive Baseline Comparison Runner for Q-TensorFormer.
Benchmarks Q-TensorFormer against 11+ architectural baselines:
1. Dense Transformer (FP32)
2. Dense Transformer (FP16)
3. INT8 Post-Training Quantization (PTQ)
4. INT4 Post-Training Quantization (PTQ)
5. Grouped-Query Attention (GQA 4:1)
6. Multi-Query Attention (MQA 8:1)
7. Static Tensor-Train (Rank 4)
8. Static Tensor-Train (Rank 8)
9. Dynamic Early-Exit (FastBERT style)
10. Heavy Hitter KV (H2O / StreamingLLM)
11. Mixture of Experts (MoE Top-1 Sparse Routing)
12. Q-TensorFormer (Quality Preset)
13. Q-TensorFormer (Balanced Preset)
14. Q-TensorFormer (Edge-SLA Preset)
Reports:
- Absolute values for 17 hardware, computational, and quality metrics.
- Explicit provenance tags (MEASURED, ESTIMATED, SIMULATED, PROJECTED, N/A).
- Direction-aware relative percentage improvements vs every baseline.
- Best-case and worst-case operating regime diagnostics.
- Exports to JSON, CSV, and GitHub-flavored Markdown.
