Abstract: The present technology relates to an information terminal, an information processing device, and a program that make it possible to find out that an installation status has changed. The information terminal transmits information at predetermined time intervals. The information terminal causes information that is to be transmitted in a normal state of installation to be transmitted in a case where, after a return from a sleep state, a flag indicating whether or not an abnormal state of the installation has been detected indicates that the abnormal state has not been detected, and causes information different from the information that is to be transmitted in the normal state to be transmitted in a case where, after the return from the sleep state, the flag indicates that the abnormal state has been detected. The present technology can be applied to a home communication system.

Abstract: An apparatus includes: a product-sum operation circuit that executes a product-sum operation with a plurality of input values quantized by power expression and plurality of weigh coefficients quantized by power expression corresponding to respective input values, in which an exponent of each of the input values is expressed by a fraction having a predetermined divisor in a denominator, an exponent of each of the weigh coefficients is expressed by a fraction having the divisor in a denominator, the product-sum operation circuit executes the product-sum operation using a plurality of addition multipliers based on a remainder when a value obtained by adding a numerator related to the exponent of each of the input values and a numerator related to the exponent of each of the weigh coefficients is divided as a dividend, and each of the addition multipliers is a floating-point number with an exponent part having a radix of 2.
