A calibration waveform reduced mean relative six-bit code error at 86 selected processed SEEG sites in eight people with known pulse times

We tested voltage codes on public processed SEEG from eight people. Each of 86 selected sites used five early pulses for fitting and five later pulses for testing. All codes had separate fitted ranges and known pulse times. At six bits per sample, a shared calibration waveform gave a mean site log error ratio of -1.66 dB against direct coding. The 95% person bootstrap interval was -2.79 to -0.54 dB. Seven of eight people had a decrease. The arithmetic mean of scaled after-pulse error fell by 7.0%. The waveform added 3,932 bytes per site. Four-bit waveform error exceeded six-bit direct error at 84 of 86 sites. Thus, this test did not establish a byte saving at matched error. The package preserves input windows, code, packed streams, source hashes, results, figures, and reproduction steps. The study is exploratory and uses a cohort from prior work.

    Its encoding benchmark showed that separate before and after voltage ranges change the comparison. We used separate tuned direct ranges as the baseline and tested a new shared waveform residual and constant control on the reused cohort.
