  • Publication number: 20210182679
    Abstract: A data processing system includes: a neural network processing unit that performs a process determined by a neural network including an input layer, one or more intermediate layers, and an output layer; and a learning unit that trains the neural network by optimizing an optimization parameter of the neural network based on a comparison between output data output when the neural network processing unit subjects learning data to the process determined by the neural network and ideal output data for the learning data. The neural network processing unit performs, in a learning process, a coefficient process of multiplying intermediate data representing input data input to an intermediate layer element constituting the intermediate layer of an M-th layer (M is an integer equal to or larger than 1) or representing output data from the intermediate layer element by a coefficient the absolute value of which increases monotonically in accordance with progress of learning.

  • Publication number: 20200349444
    Abstract: A data processing system includes a learning unit that optimizes optimization target parameters of a neural network on the basis of a comparison between output data that is output by execution of a process according to a neural network on learning data and ideal output data for the learning data. An activation function f(x) of the neural network is defined, when a first parameter is C and a second parameter being a non-negative value is W, as a function in which an output value for an input value is a value continuous within a range of C±W, the output value for the input value is uniquely determined, and a graph of the function is point-symmetric with respect to a point corresponding to f(x)=C. The learning unit optimizes the optimization target parameters that include the first parameter and the second parameter.
