    Abstract: A monitoring system includes storage, and one or more processors. The storage stores at least one of first output data that is obtained from a learning model, or first statistical information that is obtained from the first output data. The processors calculate a degree of abnormality indicating a degree of change in statistical information of second output data with respect to the first statistical information, or a degree of change in the statistical information of the second output data with respect to second statistical information. The processors determine whether or not there is occurrence of an abnormality in the learning model, on the basis of the degree of abnormality.

  • Patent number: 10147998
    Abstract: An antenna of a communication terminal is disposed on a side on which a bottom surface of a reflective plate, which is included in a display, is present. When the reflective plate is irradiated by an LED light source, the antenna cannot be seen from the side on which a display screen of the display is disposed. Accordingly, an antenna coil of the antenna does not need transparent electrodes and can be made of various materials each having a high conductivity. Therefore, the antenna has high sensitivity, low manufacturing cost, and very efficiently performs near field communication with an external device located on the display screen side of the display.
