A map trained on other sites gave a 0.63% mean gain for 100–500 ms SEEG forecasts at 86 sites in eight patients with five calibration pulses per site and complete donor calibration

We tested whether data from other stimulation sites could improve a late SEEG forecast with five local calibration pulses. The public source was OpenNeuro ds004696 v1.0.1. The test used 86 fixed selected readouts in eight patients. There were 430 calibration pulses and 430 test pulses. The fixed map used 16 cosine components and other sites in the same patient. With complete offline donor calibration, mean error fell by 0.630% relative to a scaled mean response. The descriptive 95% patient interval was 0.282% to 0.952%. The matched before-pulse mean gain was −0.466%. The correct input gave a 0.418% advantage over a shifted input. A secondary rule used only donor calibration that ended before the input. Its mean gain was 0.348%. A reproduced full sample local model gave a 2.496% mean gain. The shared map did not establish an advantage over that local model. The cohort was reused. The target was centered 100–500 ms voltage after a pulse. The package preserves exact input arrays, fixed models, controls, losses, figures, and source hashes. GPL analysis and retrieval scripts are omitted, so the archived results cannot be rerun from this SCI package. An early-input-only forecast interface reproduced all 860 saved queries exactly.

usesSix-bit asinh encoding gave lower balanced error than tuned uniform encoding with one range in processed SEEG at 86 selected sites after five calibration pulses per site
We used its selected bipolar voltage arrays, pulse order, contact maps, source hashes, retrieval code, and source processing files. These files supplied the public SEEG test set and allowed exact reconstruction from complete source files. We tested digital encoding, a new question on the same cohort.
usesEarly SEEG template deviation gave 52.7% mean agreement with late error ranks after five fit pulses at 86 sites in eight patients
Used its fixed selected pulse voltage archive, corrected event order, inherited reference errors, and retrieval code. The present test asks whether 20 to 100 ms voltage ranks the later error of a fixed 100 to 500 ms waveform forecast. It uses the same cohort and supplies no independent patient sample.
