Title: Feature data selecting method for data processor
Inventor: MATSUMOTO KOJI
IPC: G06T7/00
Filed: 1989-12-25
Abstract: PURPOSE:To effectively select the feature data by deleting the feature data having high similarity of output at mutual exchange of partial corresponding feature data among those different input data and reducing the quantity of each input data. CONSTITUTION:A figure (a) shows an ignition pattern of neurons of a neural layer 23 with a character 'A' inputted from a camera 11. A figure (b) shows an ignition pattern of neurons with an inputted character 'B' respectively. Under such conditions, more neurons are ignited at the left side than those of the right side in case of 'A'. Meanwhile more neurons are ignited at the lower left side in case of 'B'. Thus the ignition patterns varies in accordance with the data inputted to the layer 23. In this respect, the feature data having high similarity of output are deleted when the partial corresponding feature data are mutually exchanged among those different input data. Then the quantity of each input data is reduced. Thus the feature data can be effectively selected when the effective feature data are not satisfactorily selected.

The electron - hole pairs are accelerated by a bias voltage to reach to an electrode and turn into an ionization current, a direct current component is removed from the ionization current concerned through a capacitor, the direct component removed ionization current is amplified and outputted as an output signal. At this point, the processing affected layer of high resistance introduced by a lapping or a polishing process is removed by etching so as not to enable an effective voltage applied to a sensing layer of compound semiconductor crystal to decrease to be much smaller than an applied voltage. A metal electrode is formed of platinum through an electroless plating method. This method is employed so as to prevent a leakage current from increasing sharply due to the injection of carriers when a voltage is applied.
