  • Publication number: 20210248422
    Abstract: The present invention enables the structure of a neural network to be quantitatively analyzed. An analyzing unit calculates, for each of combinations of a dimension of input data and a cluster, a sum of squared errors between an output of each unit belonging to the cluster when a value of the dimension of the input data is replaced with an average value of the dimension of the input data included in learning data and an output of each unit belonging to the cluster for the input data before replacement as a relationship between the combinations, and calculates, for each of combinations of the cluster and a dimension of output data, a squared error between the value of the dimension of the output data when an output value of each unit belonging to the cluster is replaced with an average output value of each unit of the cluster when the input data included in the learning data was input and the value of the dimension of the output data before replacement as a relationship between the combinations.

  • Patent number: 8134253
    Abstract: A load driving circuit (20) according to the present invention, for carrying out PWM control to cause currents of respective light emitting diode lines (3-1 . . . 3-N) connected in parallel, each of the light emitting diode lines (3-1 . . . 3-N) including a plurality of light emitting diodes (4) connected in series, causes timing at which a current of any one of the light emitting diode lines (3-1 . . . 3-N) is turned on or off to be different from timing at which current(s) of at least another one of the light emitting diode lines (3-1 . . . 3-N) is(are) turned on or off. This makes it possible to provide a load driving circuit which (i) does not have a reduction in a degree of freedom in selecting a frequency of a PWM control signal that is used to control loads, (ii) does not prevent a peripheral circuit from following the PWM control circuit, and (iii) prevents generation of sounds.
