Previous coarse sweep peaked at ARI_full = 0.393 @ γ=2.0 (item 18).
Fine-γ sweep at {1.25, 1.5, 1.75, 2.0, 2.25, 2.5, 2.75, 3.0, 3.5}
on the default N=1024 SBM:
γ=1.25 ari_full=0.278 distinct= 45
γ=1.5 ari_full=0.323 distinct= 72
γ=1.75 ari_full=0.348 distinct= 70 ← exactly ground-truth count
γ=2.0 ari_full=0.393 distinct=109
γ=2.25 ari_full=0.425 distinct=156 ← new peak
γ=2.5 ari_full=0.425 distinct=171 ← plateau with γ=2.25
γ=2.75 ari_full=0.290 distinct=202
γ=3.0 ari_full=0.338 distinct=188
γ=3.5 ari_full=0.222 distinct=200
**CPM-Leiden full-partition ARI is now 0.425 vs modularity-
Leiden's 0.107 — a 3.97× improvement, 57 % of the AC-3a 0.75
SOTA target.**
Two non-obvious facts from the sweep:
(a) Peak ARI is at γ ∈ [2.25, 2.5] with 156–171 communities —
MORE than the ground-truth 70 modules. CPM's over-splitting
is aligned enough with ground truth that ARI tolerates it.
(b) γ = 1.75 exactly recovers 70 communities (the ground-truth
module count) but scores LOWER (0.348) than γ = 2.25's 156
communities. On this substrate, 'match the community count'
and 'maximize ARI' are distinct optimization targets.
Updated ADR §17 item 19 + §13 follow-up entry naming
CPM-refinement as the likely next lever to close the remaining
1.76× gap to the SOTA target.
Files:
- tests/leiden_cpm.rs: γ-list extended to 18 values covering
{1.0 ... 64.0} with fine resolution around the peak
- docs/adr/ADR-154: §17 item 19 added with the fine-sweep table
and the two non-obvious observations about count-vs-ARI
No production-code change. All 94 prior tests unchanged.
