摘要： PURPOSE:To identify the cause of an abnormality as well as the information whether normal or abnormal by providing a neural circuit network device identifying the cause of the abnormality in the case an unknown sensor output is input. CONSTITUTION:If a foreign material 5 comes in and partial discharge 6 is caused, internal insulation gas is vibrated and the vibration propagates to a tank 2. As a result, the tank 2 mechanically vibrates and the vibration is obtained as acceleration change in an accelaration sensor 7 output. A calculator 8 converts it to a spectrum with an FFT and a calculator 9 time-averages it. A calculator 10 normalizes the magnitude and inputs in a neural circuit network device 11. As in the neural circuit network device 11, the relation between the abnormality cause and the spectrum memorized as learned data is stored as each combining weight 19, a neural element corresponding to the abnormality cause outputs a large power based on the memory when an unknown spectrum of the acceleration sensor is input. As the result, not only abnormal or normal is identified but also the generation of the abnormal state corresponding to the label according to the output layer 18b of the neural element which is generated in an electric appliance such as gas insulation breaker, is identified.

摘要： PURPOSE:To obtain an answer of an optimization problem regardless of some troubles of the nerve simulation elements and the connection elements by allocating the approximately same working states to the problems to be solved by the nerve simulation element groups for multiplexing and also multiplexing the connection element groups which feed back the output signals of the nerve simulation elements. CONSTITUTION:Each nerve simulation element contained in the nerve simulation element groups 11 has a nerve simulation circuit network 1 which calculates the sum total of the feedback signals received via each connection element 21 and the independent signals 31 approximately equal to each other and inputted separately from those feedback signals and at the same time secures locally a minimum energy state for an aggregate. Furthermore, a computer 3 is added to perform the transfer of information to the network 1. Thus it is possible to obtain an answer of a combined optimization problem in a stable way regardless of some troubles of the nerve simulation elements and the connection elements.

摘要： PURPOSE:To obtain a machine learning method wherein a knowledge to be learnt is put in order as a generalized knowledge system, the number of combinations to be considered is covered by the small number of data and the knowledge can be utilized in a short time and to provide its apparatus. CONSTITUTION:The state of an electric-power system after a simulation has been performed by using significant-relationship data on a concept indicating that the combination of a plurality of switches or the like is in the same relationship as one connection maker is expressed in the unit of a connection maker instead of that which has been expressed in the unit of a switch. Thereby, the content of operating-routine information 1 is simplified to an operating routine in the unit of the connection maker instead of an operating routine in the unit of the switch. Peculiar names with which the connection maker in the simplified operating-routine information and the switch in the same relationship as the connection maker are provided are changed to general names. The simplified operating-routine information and the apparatus configuration of the connection maker are registered in a database 3.

摘要： PURPOSE:To obtain a desired output fast by storing a sampling function which is moved in parallel by input values of learning data in neural elements in an intermediate layer and setting the output value of the learning data as coupling weight for coupling the intermediate layer with an output layer. CONSTITUTION:The neural network device stores the sampling function which is moved in center in parallel by regularly obtained input values x1, x2, and x3 in the neural elements 11 in the intermediate layer 11b. For learning data consisting of pairs of the input values and output value (y) as to the respective pairs. The output value of the learning data is assigned as the coupling weight 12 between the intermediate layer 11b and output layer 11e. For example, when repetitive arithmetic need not be performed as learning and an optional input value of the learning data is supplied to the neural network device, the desired learnt output value is obtained, so the calculation time can be shortened since the execution time accompanying the learning includes no repetitive arithmetic.
