  • Publication number: 20200257928
    Abstract: The first apparatus (2100) computes an determination accuracy representing a probability that it is correct to use, as a determination result, the first result. The first apparatus (2100) outputs the first result as the determination result in a case where the determination accuracy is greater than a first threshold value, and outputs a second result as the determination result in a case where the determination accuracy is smaller than a second threshold value. In a case where the determination accuracy is equal to or greater than the second threshold value and is equal to or smaller than the first threshold value, the first apparatus (2100) requests the second apparatus (2200) to perform the predefined determination on the determination target. The first apparatus (2100) updates at least one of the first threshold value and the second threshold value based on the determination result output by the second apparatus (2200).
