PPL = Perplexity (lower is better). K = number of BSA terms. Δ = deviation from FP32 baseline. K=2 is the optimal sweet spot (near-lossless at 2.7× compression).

Key Finding: K≥4 Provides No Benefit

Our sweep analysis shows that K=2 is the optimal decomposition level. Adding more terms (K=3, K=4) provides diminishing returns — the perplexity delta at K=2 is already within measurement noise (≤+0.08). This means production deployments should use K=2 for the best balance of compression and quality.

Methodology

Dataset

WikiText-2 test split (4,358 sequences) — standard LLM evaluation benchmark.

Quantization

K-term BSA decomposition. Each FP16 weight decomposed into K signed powers of two (shifts + adds).

Metric

Perplexity (PPL) — measures prediction quality. Lower is better. Δ shows deviation from FP32 baseline.

Hardware

AWS Graviton4 r8g.4xlarge (16 vCPU, 128 GB RAM, ARM Neoverse V2). CPU-only — no GPU.

Reproducibility

All benchmarks are fully reproducible. Scripts available upon request for pilot evaluators.
