Journal ArticleDOI
An architecture of neural networks with interval weights and its application to fuzzy regression analysis
TL;DR: This paper proposes an architecture of neural networks that have interval weights and interval biases, and develops a learning algorithm derived from the cost function in a similar manner as the BP (Back-Propagation) algorithm.
Proceedings ArticleDOI
Fuzzy neural networks with fuzzy weights and fuzzy biases
TL;DR: An architecture of multi-layer feedforward neural networks whose weights and biases are given as fuzzy numbers is proposed, and a learning algorithm of the fuzzy neural networks is derived for real input vectors and fuzzy target outputs.
Patent
Method and apparatus for recording and analyzing an interaction log
Toshiyuki Asahi,Hidehiko Okada +1 more
TL;DR: In this article, an apparatus for recording an interaction log includes an event detector for determining whether a reference event occurred in an interactive system, and a latching mechanism latches information to be transferred from an input unit to a processing unit so that the processing unit does not respond to the reference event.
Journal ArticleDOI
Interpolation of fuzzy if-then rules by neural networks
TL;DR: The ability of each approach to interpolate sparse fuzzy if-then rules is examined by computer simulations and high fitting ability of approaches and high interpolating ability of those in the second category are demonstrated.
Patent
Automatic GUI system operation device and operation macro execution device
TL;DR: In this article, a screen of a system is comprehensively shifted by automatically operating a system having a GUI and images on the screen are recorded at respective time instances, and an operation event for executing an operation of the selected operation object is generated by an operation generator unit (109) and output to a program execution unit (101) for controlling an execution of an execution program of the system.
