Abstract
In the above paper [1], we proposed a novel framework that uses a constrained formulation of sum of squared correlation (SSCOR) approach as an alternative method for designing a spatial filter for steady-state visual evoked potential (SSVEP) based brain-computer interfaces (BCIs). To evaluate the target detection performance of the SSCOR method, the task-related component analyses (TRCA) were used as a benchmark [2]. The study used the SSVEP benchmark dataset containing 40 target data collected from 35 subjects [3]. During the evaluation of the proposed method, the SSCOR provided very high detection performance and outperformed the TRCA method and the results were reported.
