Seven calibration pulses gave a 3.33% mean person error reduction over five for centered 20 to 500 ms SEEG at 86 selected readouts in eight sessions

We tested the value of two more early calibration pulses for a later SEEG response forecast. The public source was OpenNeuro ds004696 version 1.0.1. We kept 86 readouts selected with the first five good pulses in eight epilepsy sessions. Five and seven early pulses forecast the same final three good pulses at each site. The primary score used individual responses and centered voltage from 20 to 500 ms. The mean person error reduction was 3.33%, with a descriptive 95% person interval of 1.34% to 5.94%. All eight person reductions were positive. Seven pulses required 40% more retained good calibration pulses. Error against the mean of the same three targets fell by 7.09%. An exact identity showed that both targets had the same absolute error decrease. Averaging reduced the starting loss and raised the percent gain. A separate risk bound needs a fixed waveform and independent pulse noise with common energy. It does not bound the fitted method in these selected data. The before-stimulation control did not establish a response-specific cause of the gain. This reused cohort is not an independent replication or an online BCI test. The package preserves all pulse windows, predictions, code, tables, three figures, proof functions, source hashes, and instructions. Two complete public source derivatives were rebuilt exactly. Public metadata and parent hashes were checked for all eight people.

    We use its shared energy scale for a centered calibration mean. We fit this scale separately at five, six, and seven pulses and compare the same later targets.

    We use its complete chronological pulse windows, fixed readouts, public source recipe, and source records. We add fixed counts of five and seven with the same final three targets and exact target accounting.

  3. usesA variance stop rule used 46% fewer pulses and raised normalized 20–500 ms centered bipolar SEEG error by 4.5% versus five-pulse scaling in eight sessions sci:sha256:8955e9a601f2413d772c6b6b57b9b299de1d9a902c02ab8c2f364acf60ae3587

    Its earlier pulse-count and stop-rule results informed the fixed count question. We test counts above five at selected readouts. This is a related analysis of the same cohort.

    We keep its first-five readout choices and use its candidate edge records and comparison windows through the complete pulse input package.

    Its earlier fixed budget allocation result informed the calibration cost question. We hold the count at five or seven for every site and do not claim a new allocation rule.
