We apply the independent component analysis (ICA) to the real data from a gravitational wave detector for the first time. Specifically we use the iKAGRA data taken in April 2016, and calculate the correlations between the gravitational wave strain channel and 35 physical environmental channels. Using a couple of seismic channels which are found to be strongly correlated with the strain, we perform ICA. Injecting a sinusoidal continuous signal in the strain channel, we find that ICA recovers correct parameters with enhanced signal-to-noise ratio, which demonstrates usefulness of this method. Among the two implementations of ICA used here, we find the correlation method yields the optimal result for the case environmental noises act on the strain channel linearly.

独立成分分析在 iKAGRA 数据中的应用
我们首次将独立分量分析 (ICA) 应用于来自引力波探测器的真实数据。具体使用2016年4月的iKAGRA数据，计算引力波应变通道与35个物理环境通道的相关性。使用发现与应变密切相关的几个地震通道，我们执行 ICA。在应变通道中注入一个正弦连续信号，我们发现 ICA 以增强的信噪比恢复了正确的参数，这证明了该方法的实用性。在此处使用的两种 ICA 实现中，我们发现相关方法在环境噪声线性作用于应变通道的情况下产生了最佳结果。
