Higher-order joint activation moments for the Phase 2 (v2-phase2) benchmark MLPs
of the ARC WhiteBox Estimation Challenge 2026 — the 1024-wide, 16-layer analog of
arc-whestbench-higher-moments-2026.
Source MLPs: the 100 MLPs of the mini split of
aicrowd/arc-whestbench-public-2026
at revision v2-phase2 (width 1024, depth 16, He-init, no biases, fp32 weights,
input x ~ N(0, I), forward a_l = relu(a_{l-1} @ W_l)).
Moments are estimated from N =… See the full description on the dataset page:
