Noise subtraction from KAGRA O3GK data using Independent Component Analysis
Noise subtraction from KAGRA O3GK data using Independent Component Analysis24 should divide it into the smaller part in which the transfer function can be approximately regarded as constant. Or alternatively, the formulation of ICA incorporating the time dependence needs to be considered. Such an is...

| Sumario: | Noise subtraction from KAGRA O3GK data using Independent Component Analysis24 should divide it into the smaller part in which the transfer function can be approximately regarded as constant. Or alternatively, the formulation of ICA incorporating the time dependence needs to be considered. Such an issue will be further investigated in our future work. Since current level of subtraction is insufficient to provide drastic change in SNR, effect on the signal detection is not investigated in this work. After establishing method incorporating non-stationarity and also non-linearity, it is worthwhile to perform cleaning of the whole data segments and give a prediction for signal detection.
