Solid-state LiDAR public benchmark v0.4

This report records the checked public-data-only v0.4 run. It is a paired temporal-holdout comparison of the frozen continuous_time_outlier_mad_scale=2.5 candidate against the uniform/no-rejection baseline. The candidate was fixed from AgRob train-only diagnostics before this matrix was scored.

  • Schema: slac.solid_state_cross_dataset_benchmark/v0.2
  • Protocol: bounded_continuous_time_uniform_vs_adaptive_mad25_solid_state_lidar
  • Spec SHA-256: f0b9acb4d34171ad10787ffaba6dc0e4e85264b5dc14f6f76828f9255e86227f
  • Provenance sources: 142

Summary

  • Scored datasets: 3/3
  • Scored paired replicates: 27/27
  • Adaptive wins: 25/27 (0.926)
  • Uniform wins: 2/27
  • Mean holdout improvement: 57.20%
  • Median holdout improvement: 72.79%
  • Bootstrap 95% CI: [45.69, 67.43]%

Positive improvement means the adaptive candidate has lower final temporal- holdout point-to-plane RMSE than uniform_none under the frozen protocol.

Public pair/control Replicates Adaptive win rate Mean improvement (95% CI) v0.3 mean Outcome
AgRob Modular-e Livox MID-70 ↔ RS-LiDAR 9 0.778 +16.85% (+5.90, +27.80) −1.34% adaptive 7/9; two retained counterexamples
TIERS LidarsCali VLP-16 ↔ Livox Horizon 9 1.000 +82.48% (+80.03, +85.17) +78.76% adaptive 9/9
AIST GLIM identity control 9 1.000 +72.26% (+70.76, +73.60) +65.67% adaptive 9/9

Compared with v0.3, the aggregate mean improvement increases by 9.50 percentage points, AgRob changes from mixed-negative to 7/9 adaptive wins, and the other two public controls remain adaptive wins in every replicate.

Failure and interpretation gates

All 54 variant artifacts have rank 6 and sufficient holdout support. Nine of the 54 variants carry the explicit max_iterations failure category; the declaration keeps require_converged: false, so those rows remain visible and scored rather than being silently removed. This is a performance caveat and a follow-up budget-sensitivity item, not evidence of independently measured absolute accuracy.

AgRob and TIERS use trajectory_only reference mode and GLIM is an identity control. The public recordings do not provide independently surveyed extrinsics or absolute clock truth. Therefore this result supports the frozen paired temporal-holdout protocol; it is not a universal SOTA or absolute calibration-accuracy claim.
