以下为文章摘要：

Brain-Computer Interface (BCI) is a direct communication medium between brain and outside world. This study focuses on a Steady-State Visually Evoked Potential (SSVEP)-based BCI due to its large number of instruction set. However, it is still challenging to decode multi-class SSVEPs. To improve target identification accuracy, we propose a Siamese Correlation Analysis model (SiamCA), which involves two feature extractors with tied parameters and a top decision network. We consider two datasets for benchmarking the performance of the proposed model and compare it with FBCCA, TRCA, ensemble-TRCA and a deep learning method named ConvCA. The proposed method realize a significantly higher average classification accuracy than the compared method at different data length (0.2-1.0s) on two datasets. This suggests that the proposed SiamCA model is a promising methodology for target identification of SSVEPs and could further improve the performance of SSVEP-based BCI system.
