Automatic analysis of the neutron-$$gamma$$ pulse shape discrimination has been developed for the neutron emission profile monitor, which uses stilbene scintillation detectors, in JT-60U. In the automatic analysis, linear discriminant function is applied to determine the line dividing between neutron events and $$gamma$$-ray events on the 2D map. In order to verify the validity of the determined line, the pulse shape discrimination quality is evaluated with the ratio of $$gamma$$-ray events to neutron events, namely contamination by $$gamma$$-ray. As a result, it is clear that $$gamma$$-ray contamination is below to statistical error with the time resolution of 10 ms.
