A weight selected from five early pulses did not show lower 20 to 500 ms SEEG forecast error than one scale at 86 selected sites in eight sessions
This study tested a sharing weight chosen from five early electrical pulse responses. It used public OpenNeuro ds004696 version 1.0.1. One fixed bipolar readout at each of 86 sites was selected from early data in eight epilepsy patient sessions. Five early heldout folds chose an exact continuous weight between one waveform noise scale and four frequency scales. The final forecast used all five early pulses. The test used 610 later records and omitted two known duplicate records. The mean patient error reduction from one scale was -0.092%, with a descriptive 95% patient interval of [-0.432%, +0.231%]. Five of eight patients had lower error. The early selection criterion improved by 0.622%, but this did not establish a later gain. The package preserves the exact weight proof, all selected voltage windows, fitted forecasts, pulse errors, three figures, source hashes, code, and reproduction instructions. A fresh public source file rebuilt all 61 selected records for one patient exactly. This is an exploratory test in a reused cohort. It does not establish equivalence, live interface performance, or clinical benefit.

Used the earlier calibration-only sharing test as method context. That study selected sharing across readouts at a site. This study selects a continuous weight between a one-scale and four-frequency forecast at one fixed readout and tests later single-pulse errors.

Used band_forecast.py without changes for the one-scale and four-frequency endpoints, the fixed frequency groups, and parent pulse losses for an independent endpoint reproduction check. Used its prior duplicate-record finding to specify two omissions before the new weight outcomes. The new rule selects a continuous sharing weight using only early pulses.
