source separation

there are 21 machines and 3 vibration sensors installed only in machine number 2. Each sensor gathers vibration data on three axes and each sensor gives 9 outputs . so the point is even though the sensors are set up in machine 2 when getting the vibration data, sensors are not only getting the vibrations from machine 2 but also from the other working machines as well. All 21 machine working statuses and all three sensors' outputs are given by csv file. so needed to do source separation for the machine2
