  • Signal judgment method, signal judgment apparatus, program, and signal judgment system
    Patent number: 8712740
    Abstract: Provided is a high-accuracy signal judgment method for noise or vibrations of a living environment. Provided is a signal judgment method associated with noise or vibrations of a living environment. The signal judgment method includes: inputting, into a model equation of a to-be-measured/analyzed target, unknown data; and obtaining an output value as a probability value of whether the unknown data is a to-be-measured/analyzed target. The model equation of the to-be-measured/analyzed target is created with the use of measured already-known data. The model equation is created by prediction model equation calculation means. Incidentally, a logistic regression equation can be used as the prediction model equation.
