An adaptive equalizer detects characteristics of a transmission line in radio and cable communications and equalizes received signals by using the detected results. Equalization is for not only linear distortion but also nonlinear distortion in accordance with variation of characteristics of the transmission line. The adaptive equalizer includes a characteristic detection unit 11 for detecting real part and imaginary parts of a transfer function by using an output signal corresponding to an input signal of an object to be equalized to compensate for deterioration, for example a transmission line; and an equalizing unit 12 for equalizing an output signal of the object to be equalized 10 in accordance with an unknown input signal by using the detected result of the characteristic detection unit 11.

A feedback control device at a certain control time, predicts a feedback quantity at the next control time on the basis of a feedback quantity fed back from a controlled object and then performs a control operation based on the predicted feedback quantity. The feedback control device includes a predictive control unit for producing such an actuating signal as to decrease a deviation between the predicted feedback quantity and a desired value. The actuating signal is used to control the controlled object. This eliminates the detrimental effects of time delays associated with the controlled object or the control device, thus ensuring good control. The use of the predictive control unit permits the controlled quantity from the controlled object to converge to the desired value monotonically and quickly. The predictive control unit may use a layered neural network having an input layer supplied with a feedback quantity and an input value corresponding to an actuating signal, and an output layer outputting a predicted feedback quantity. The deviation is back propagated from the output layer to the input layer by a relaxation algorithm in order to update the input value. The updated input value is applied to an actuating unit as an actuating signal, thereby controlling the controlled object.

The adaptive input-output apparatus comprises a data holding portion which holds sample data for determining an input/output function, a data selector which uses a predetermined evaluation standard to select valid sample data from said sample data, and an input/output portion which determines an input/output function in accordance with sample data selected by the data selector and outputs on the basis of the input/output function and in accordance with external input. Accordingly, the adaptive input-output apparatus removes unnecessary sample data or uses a predetermined condition to remove sample data having a small evaluation quantity and validity when the input/output function is determined, extracts sample data having a high validity and determines an input/output function using a reduced set of sample data.

A network is provided in which the direct model of the controlled target is learned, and an actuation amount for realizing a target control amount is generated using this network in accordance with the relaxation algorithm. A recognizing network and a prediction network are provided, wherein the recognition result of the recognizing network is input to the prediction network, and the prediction result of the predicting network is fed back to the recognizing network. Moreover, the predicting network is utilized so as to generate a command relating to the motion in accordance with the relaxation algorithm.

A design support apparatus extracts feature data corresponding to design data to be searched upon receiving the design data to be searched. The apparatus checks the extracted feature data against the feature data associated with the feature associated information, ordering the design data associated with the feature associated information in descending order of similarity to the design data to be searched, retrieving one piece of the ordered design data. The apparatus generates a classification hierarchy consisting of pieces of classification data obtained by classifying a set of the retrieved design data based on a degree of feature similarity using the feature data associated with the feature associated information. The apparatus selects the design information closely associated with the classification data by fetching the design information corresponding to the design data contained in the classification data from the design associated information associating the design data and the design information.
