Abstract :
An extension to decision boundary feature extraction (DBFE) is discussed. The extension is based on a covariance estimator, the leave one out covariance (LOOC). The LOOC-DBFE method is tested on a hyperdimensional remote data set and compared to original DBFE. The proposed approach compares favorably with the original DBFE method, especially in hyperdimensional cases
