Selection of time bins from five pulses reduced storage and increased mean later SEEG error at 86 sites in eight reused sessions
We tested whether five early stimulation pulses can select a compact voltage forecast. The public SEEG data came from OpenNeuro ds004696 version 1.0.1. We used 86 selected stimulation sites in eight reused epilepsy sessions. The first five pulses at each site fit each forecast. We tested the forecasts on 611 later unique pulse records. Mean patient error increased by 3.14% from the full-resolution noise-scaled mean. The descriptive 95% patient bootstrap interval for this increase was 0.83% to 5.57%. The two-sided sign-flip value was 0.0625. Mean patient model storage decreased by 46.72%. A fixed 128-bin control decreased storage by 86.63% and increased mean error by 0.56%. The result concerns centered bipolar voltage from 20 to 500 ms after stimulation. The package contains exact input windows, a forecast tool, stored models, all scores, figures, source hashes, and reproduction code. A fresh source download reproduced all 61 pulse windows for one patient. A full analysis replay reproduced all score files and models. This exploratory test does not establish performance in a live brain interface or on a new day.

We used its five-pulse clipped cross-pulse noise scale as the full-resolution reference. We applied the same scale formula after each time projection and in each omitted-pulse fitting fold.

The input readouts use its first-five-pulse choice of one remote bipolar pair per site. We preserved its choice table and did not search for a new spatial readout after scoring later pulses.

Its fixed temporal projection result motivated the test of resolution selected from early pulses. The present work uses contiguous time bins, all later unique pulse records at selected readouts, and a refitted projection-specific scale. The sessions and later outcomes are reused, so this is not independent confirmation.

This publication supplied the exact 1,042 selected-readout pulse records, source metadata, source hashes, and extraction code. We tested a new early-only choice of time resolution on 611 later unique records. We checked every copied input hash and freshly rebuilt all 61 records for sub-05 from the complete pinned source derivative.

- usesSixty block means gave the same SEEG detection AUC as 960 samples on five later pulses at each of 85 selected sites in eight people
Its contiguous time-bin forecast test in reused SEEG sessions motivated a separate test of waveform value reduction for detection AUC. Our main block size was fixed before new scores. We used no adaptive bin choice or forecast scale from that work. The reused sessions prevent an independent confirmation claim.
- usesA 20–100 ms energy update gave mixed forecast results in eight reused SEEG sessions with five calibration pulses
This publication supplied the exact eight-person pulse windows, original event maps, pinned source records, and range download code. We checked all 16 input file hashes. The new analysis forecasts one energy value and uses slopes from other people.
