Lower contact numbers gave mean seizure onset AUC 0.794 within mixed inferred shafts in 34 selected ds004100 SEEG patients

We tested whether contact order can rank clinical seizure onset labels without a SEEG signal feature. The fixed score was minus the final contact number. The source was OpenNeuro ds004100 version 1.1.3. Within 90 inferred shafts with both label classes, 34 selected patients had mean AUC 0.794 (95% patient bootstrap interval 0.691 to 0.885). The mean was 0.944 in 14 MTL patients and 0.421 in seven FRONTAL patients; these groups use the source surgical target. Six fixed power scores had lower mean AUC on the same contacts, while paired intervals for absolute delta included zero. The result is specific to this selected cohort and is not a clinical decision rule. Contact selection depended on source signal quality checks, and clinical labels defined shafts for evaluation.

Its reference-sensitive onset ranking and within-shaft power comparisons supplied prior context. We did not use its 120 s signal arrays.

usesHigh gamma added 0.017 AUC to a quadratic contact number model in 33 SEEG patients, with a refitted patient interval that included zero
Its contact number evidence motivated our fixed baseline. We test added high gamma with complete patient exclusion.
supportsLower contact numbers gave mean AUC 0.790 for public onset marks within inferred shafts in 19 external SEEG patients
The NIH and Johns Hopkins data extend the reported HUP contact number pattern. Mean external number AUC was 0.790 within inferred shafts. This study also uses the earlier benchmark direction.
usesA refitted interval included zero for high gamma gain over contact number under patient holdout in 33 SEEG patients
Its contact number result motivated the location baseline. We did not use its numerical outputs. We formed the current features from the source covariance package.
usesAdding high gamma gave an uncertain mean AUC gain of 0.023 beyond contact numbers in a fixed test of 35 SEEG patients
The contact-number benchmark in this same cohort motivated the number-only baseline and the question of added signal information. Its code and numerical outcomes were not used as model inputs.
usesAdded SEEG power gave an uncertain mean AUC gain over contact number in 17 ds004100 test patients under fixed models, independence, and null symmetry
Its contact-number result in this same cohort informed the fixed position comparator. We used its description, but no derived data or code. The new test fitted joint models on separate patients and did not select mixed-label shafts for the primary evaluation.
usesHigh gamma rank with common average reference reduced mean pair loss beyond a fixed linear contact number model in 33 SEEG patients
This result showed that contact number alone can rank onset contacts. It motivated our fixed linear contact number control. We rebuilt its feature from public source tables and did not use its numerical predictions.
usesThe patient resample interval included zero added onset AUC gain from three spectral features within mixed shafts in 34 SEEG patients
This prior result set the contact order comparison and the mixed shaft scope. The new combined model tests added signal gain on the same cohort.
usesEarly gamma change increased mean onset mark AUC when fixed models excluded each of 32 SEEG patients
Its evidence that contact numbers rank clinical onset marks supported the contact number control. Its data and estimates were not combined with this study.
usesThe patient resample interval included zero added onset AUC gain from three spectral features within mixed shafts in 34 SEEG patients
This prior result set the contact order comparison and the mixed shaft scope. The new combined model tests added signal gain on the same cohort.
usesThe patient bootstrap interval for AUC gain from low frequency SEEG power above contact order included zero in 19 external patients after HUP training
Its contact order result motivated the base model and the planned comparison within contact name groups.
usesAdding high gamma raises mean AUC by 0.020 in patient holdout tests of a contact order model within named shafts in 33 HUP SEEG patients
This result supplied the contact order benchmark idea and led to the new incremental model question. Its numerical result files were not model inputs. The studies share source patients.
usesEarly gamma change had lower mean local agreement with onset marks than baseline gamma power in common average SEEG signals from 30 patients
Uses its contact-number score as a fixed descriptive benchmark on the new local boundaries. Its signal data and numerical results are not new study inputs.
