A shuffled random split would leak time-autocorrelation and inflate AUC; that mistake is deliberately avoided.","Per-fold held-out AUC ranges 0.694..0.797; the worst fold (sparse-positive late-May window) is the honest lower bound. The headline number is the mean.","The published auc_composite is the mean held-out CV number. The live per-country composite re-fits the winning method on all labels (standard once a method is selected), but the public metric stays the honest held-out figure.","Components have different time resolutions (DBSCAN/STL/burst = day, HDBSCAN = week). Each 'today' score is treated as a same-day snapshot.","'Anomalous' != 'censored'. A high composite means the day looks unusual on multiple axes; ground-truthing is still required.","Burst and HDBSCAN-drift are near-static 'current snapshot' signals applied at past label dates for evaluation, so their historical AUC is weak — DBSCAN and STL carry most of the discriminative load.","Composite renormalises weights over present detectors; a country with only 2/4 detectors still gets a composite."],"leaderboard":[{"agreed_3_of_4":true,"agreed_majority":true,"all4_strong_flags":{"burst":true,"dbscan":true,"hdbscan":false,"stl":true},"composite":0.691114,"country":"US","country_name":"United States","n_all4_present":4,"n_all4_strong":3,"n_detectors_present":4,"n_detectors_strong":3},{"agreed_3_of_4":true,"agreed_majority":true,"all4_strong_flags":{"burst":true,"dbscan":true,"hdbscan":false,"stl":true},"composite":0.669059,"country":"DE","country_name":"DE","n_all4_present":4,"n_all4_strong":3,"n_detectors_present":4,"n_detectors_strong":3},{"agreed_3_of_4":true,"agreed_majority":true,"all4_strong_flags":{"burst":true,"dbscan":true,"hdbscan":false,"stl":true},"composite":0.621629,"country":"ZA","country_name":"ZA","n_all4_present":4,"n_all4_strong":3,"n_detectors_present":4,"n_detectors_strong":3},{"agreed_3_of_4":true,"agreed_majority":true,"all4_strong_flags":{"burst":true,"dbscan":true,"hdbscan":false,"stl":true},"composite":0.610845,"country":"JP","country_name":"JP","n_all4_present":4,"n_all4_strong":3,"n_detectors_present":4,"n_detectors_strong":3},{"agreed_3_of_4":true,"agreed_majority":true,"all4_strong_flags":{"burst":true,"dbscan":true,"hdbscan":false,"stl":true},"composite":0.557242,"country":"CA","country_name":"CA","n_all4_present":4,"n_all4_strong":3,"n_detectors_present":4,"n_detectors_strong":3}],"limit":20,"n_3of4_agree":5,"n_majority_agree":17,"n_total":80,"only_3of4":true,"schema":"voidly-fused-anomaly/v1","weights":{"burst":0.25,"dbscan":0.25,"hdbscan":0.25,"stl":0.25},"_voidly_pay":{"claim_did":"https://voidly.ai/pay/claim","for_builders":"https://voidly.ai/pay/for-builders","marketplace":"https://api.voidly.ai/v1/pay/marketplace","live_demo":"https://huggingface.co/spaces/emperor-mew/voidly-pay","universal_proxy":{"url":"https://api.voidly.ai/v1/pay/proxy","example":"https://api.voidly.ai/v1/pay/proxy?u=<https-url>&to=did:voidly:<your-did>&price=0.01","page":"https://voidly.ai/pay/proxy","note":"Paywall any public HTTPS URL with one query param.
