# CSP+LDA: results on public EEG datasets

Classical method

CSP+LDA is a classical two-stage pipeline for motor-imagery EEG: common spatial patterns (CSP) learns spatial filters whose output variances differ most between two classes, and linear discriminant analysis (LDA) classifies the log-variances of the filtered signals. Ramoser, Müller-Gerking and Pfurtscheller (2000) applied CSP with log-variance features and a linear classifier to imagined left- and right-hand movement.
