Research Findings

Validated findings from Phase 3 experiments (F1–F8). Each finding includes the claim, supporting evidence, Tarka verification status, and artifact paths. Results are gated by independent recomputation and sign-off.

Filter by category:

F1

MMD converges linearly to its magnetic fixed point where GDA cycles

Convergence AnalysisVALIDATED

Claim

On symmetric zero-sum matrix games, fixed-magnet MMD (uniform anchor, lr=0.1, τ=0.1) exhibits linear (geometric) last-iterate convergence to its fixed point, while simultaneous GDA at the same stepsize cycles, bounded away from equilibrium.

Evidence

10 md5-distinct seeds, 2000 steps (exp01 iteration 2): log-linear fit on distance-to-fixed-point, last 50%: R²=0.9948 (matching pennies), 0.9015 (RPS). GDA final NashConv: 1.93 [1.90,1.96] (MP), 1.76 [1.62,1.88] (RPS), R²<0.09 (no decay).

About Tarka Verification

Tarka is an independent verification system that recomputes findings and audits experimental config hashes, seeds, and git commits. All findings in this explorer have undergone Tarka review; VALIDATED status means the claim has been independently reproduced. SIGN-OFF PENDING means the verification is complete but awaits final operator signature.

Every result includes:

  • Config hash (SHA-256) for parameter reproducibility
  • Random seed pinning for deterministic runs
  • Git commit reference for code versioning
  • Artifact paths for accessing raw data and logs
