Filtering before fourfold sample removal gave 70.6% mean balanced accuracy in later trials from eight SEEG recordings
In eight SEEG recordings from OpenNeuro ds004473 version 1.0.2, a fixed state decoder trained on early trials reached 70.59% mean balanced accuracy on later trials after filtering and fourfold sample removal, compared with 70.69% at the source rate. The paired mean change was −0.098 percentage points (descriptive 95% person-bootstrap interval −0.570 to 0.459). Simple sample removal without filtering gave 68.24% after refitting and 61.77% with the source model. Filtered buffers had 75% fewer voltage values. This is an offline, within-recording comparison of two task states in eight reused recordings; it does not measure device power, radio traffic, live control, or stimulation effects, and it is not an independent replication.
