The within-discipline failure mode is documented qualitatively in DeepSphere and DLWP-HEALPix follow-ups but not quantified at this granularity with this minimal feature pair. https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko/spherical-ml-latitude-invariance-study-2026 https://w3id.org/sciencelive/o/terms/hasDiscipline http://www.wikidata.org/entity/Q1348989 https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko/spherical-ml-latitude-invariance-study-2026 https://w3id.org/sciencelive/o/terms/hasMethodologyDescription Synthetic global SST samples are generated on a 1° lat-lon raster as a cosine-of-latitude baseline plus Gaussian noise, with optional marine-heatwave events injected as fixed-radius spherical caps with a positive temperature anomaly at uniform-random longitude and a chosen latitude band. The sphere-aware pipeline aggregates each sample onto a HEALPix-NESTED grid and applies a sphere-harmonic band-pass matched filter — a high-pass that suppresses the cosine-of-latitude SST baseline followed by a Gaussian beam matched to the cap diameter — then reads out the maximum, mean, and standard deviation of the inverse-spherical-harmonic-transform response field. The lat-lon-flat baseline cross-correlates the same SST anomaly with an equator-shape cap template and reads out the same three statistics. Both feed identical logistic-regression classifier heads. The classifiers are trained on samples with events at low latitudes only and evaluated at four progressively higher test latitude bands. The full pipeline is reproducible via the repository's environment.yml and Snakefile. https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko/spherical-ml-latitude-invariance-study-2026 https://w3id.org/sciencelive/o/terms/hasScopeDescription We test the latitude-invariance aspect of the claim. Scope: the within-discipline regime — same task (binary marine-heatwave detection), same data distribution (synthetic global SST), same training set (events confined to low latitudes only). The variable being swept is the test latitude band: we evaluate the trained classifier at progressively higher latitudes to see whether the substrate-aware pipeline preserves detection accuracy where the lat-lon-flat baseline loses it. https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko/spherical-ml-latitude-invariance-study-2026 https://w3id.org/sciencelive/o/terms/targetsClaim https://w3id.org/sciencelive/np/RAnfkEJBlKQ6KzlvlVdbMvN2px_Oz3Jth9dr5DAs-4XJ4/spherical-ml-latitude-invariance-claim-2026 https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko/provenance https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko/assertion http://www.w3.org/ns/prov#wasAttributedTo https://orcid.org/0000-0002-1784-2920 https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko/pubinfo https://orcid.org/0000-0002-1784-2920 http://xmlns.com/foaf/0.1/name Anne Fouilloux https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko http://purl.org/dc/terms/created 2026-05-06T20:23:13.819Z https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko http://purl.org/dc/terms/creator https://orcid.org/0000-0002-1784-2920 https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko http://purl.org/dc/terms/license https://creativecommons.org/licenses/by/4.0/ https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko http://purl.org/nanopub/x/introduces https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko/spherical-ml-latitude-invariance-study-2026 https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko http://purl.org/nanopub/x/wasCreatedAt https://platform.sciencelive4all.org https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko http://www.w3.org/2000/01/rdf-schema#label NP created using Declaring a replication study design according to FORRT https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko https://w3id.org/np/o/ntemplate/wasCreatedFromTemplate https://w3id.org/np/RAuLEjPp-4dTvPwMkfHggTto1CgjIftiGRAgHlyeEonjQ https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko/sig http://purl.org/nanopub/x/hasAlgorithm RSA https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko/sig http://purl.org/nanopub/x/hasPublicKey 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 https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko/sig http://purl.org/nanopub/x/hasSignature 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 https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko/sig http://purl.org/nanopub/x/hasSignatureTarget https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko https://w3id.org/sciencelive/np/RAYkg28oVS9Ns_4iDocjaKYGJXQ3VifTt96CyAy56Qrko/sig http://purl.org/nanopub/x/signedBy https://orcid.org/0000-0002-1784-2920
