Claim Text:
1. A classification estimating system for a subject's motion, based on a multi-layered neural network comprising: a first measuring device configured to measure first information as a first biosignal according to a first measuring section of the subject; a second measuring device configured to measure second information as a second biosignal according to a second measuring section of the subject; a computer-readable memory storing executable instructions; and a processor in communication with the computer-readable memory and the first and second measuring devices, wherein the processor is programmed by the executable instructions to at least: use the multi-layered neural network, the multi-layered neural network comprising an input element group in an input layer of the multi-layered neural network, an intermediate element group in a hidden layer of the multi-layered neural network and an output element group in an output layer of the multi-layered neural network, for estimating an action of the subject; wherein the input element group of the multi-layered neural network comprises a first input element group and a second input element group, the first element group comprising a first plurality of input elements, the second element group comprising a second plurality of input elements; determine values of a first input variable based on the first information; provide each value of the first input variable to each of the first plurality of input elements of the first input element group; determine values of a second input variable based on the second information; provide each value of the second input variable to each of the second plurality of input elements of the second input element group; wherein the intermediate element group of the multi-layered neural network comprises a first intermediate element group, the first intermediate element group comprising a plurality of intermediate elements; set values of a first output sensitivity according to each value of each input element of the second input element group in order for some values of a first intermediate variable to become zero, and the remaining values of the first intermediate variable to become discrete values other than zero; set values of a first multiplex output sensitivity according to each value of each element of a multiplex input element group in order for some values of the first intermediate variable to become zero, and the remaining values of the first intermediate variable to become discrete values other than zero; determine the first intermediate variable based upon a product of each value of input element of the first input element group, a value of the first output sensitivity, and the first multiplex output sensitivity such that the first intermediate variable is equal to zero when either the value of the first output sensitivity or the first multiplex output sensitivity is set equal to zero; wherein the output element group of the multi-layered neural network comprises a plurality of output elements; determine each output element based upon a value of output variables which is a product of said each value of intermediate element of the intermediate element group and a connection weight, wherein the values of output variables are zero or other than zero; wherein the connection weight corresponds to an importance of values of the intermediate elements; store correspondence relationship information that specifies a correspondence relationship between a plurality of classification information in order to classify an action of the subject, and a combination pattern of the values of said plurality of output elements which comprise discrete values of zero or discrete values other than zero; estimate said classification information for the subject's motion and information according to said first and second information based on said correspondence relationship information and the combination pattern of values of said plurality of output variables; and display the classification information.
