Abstract

Many real-world brain–computer interface (BCI) applications rely on single-trial classification of event-related potentials (ERPs) in EEG signals. However, because different subjects have different neural responses to even the same stimulus, it is very difficult to build a generic ERP classifier whose parameters fit all subjects. The classifier needs to be calibrated for each individual subject, using some labeled subject-specific data. This paper proposes both online and offline weighted adaptation regularization (wAR) algorithms to reduce this calibration effort, i.e., to minimize the amount of labeled subject-specific EEG data required in BCI calibration, and hence to increase the utility of the BCI system. We demonstrate using a visually evoked potential oddball task and three different EEG headsets that both online and offline wAR algorithms significantly outperform several other algorithms. Moreover, through source domain selection, we can reduce their computational cost by about$\text{50}\%$, making them more suitable for real-time applications.

  • Domain adaptation and domain generalization methods address cross-subject distribution shift in ERP-based BCIs but are not designed for interpretability.

    “Domain adaptation and domain generalization methods address cross-subject distribution shift in ERP-based BCIs [20], [21], [22], but are not designed for interpretability.”

    From ERP-XTTN: interpretable prototype-guided cross-attention for cross-subject ERP classification (2026) · cites this paper as [20]

    The Problem Definition (p. 3) describes domain adaptation between subjects whose EEG response distributions differ, supporting the cross-subject shift claim for ERP-based BCIs. Our copy does not establish the domain-generalization part. The interpretability contrast follows the citation and is not treated as a finding attributed to this source. (LLM, conf=0.82)

  • Transfer learning has been successfully used for BCIs.

    “Transfer learning (TL) [23], which utilizes information in source domains to improve the learning performance in a target domain, has also been successfully used for BCIs [12], [35], [36], [38], [39].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
