1. A fluid leakage diagnosing device comprising:
at least one memory storing a computer program; and
at least one processor configured to execute the computer program to,
when fluid leakage relating to a pipeline is diagnosed by employing adaptive signal processing to suppress a component of a disturbance vibration contained in a vibration measured at a prescribed location in the pipeline,
acquire distribution information that is associated with a characteristic of the pipeline and represents an actual distribution result of values of a parameter in the adaptive signal processing when performance of suppressing the component of the disturbance vibration satisfies a criterion;
based on the distribution information, estimate a probability density at which the values of the parameter exists when the performance satisfies the criterion; and
based on the probability density estimated, determine a range to search for the values of the parameter in the adaptive signal processing.
