  • Publication number: 20260170297
    Abstract: Disclosed in the present application are a reservoir computing network optimization method and a related apparatus. The method comprises: sampling an input signal to obtain a sampling signal; performing quantization processing on the sampling signal by means of at least two kinds of quantization modes, so as to obtain at least two kinds of digital signals, values of elements in different digital signals being different; inputting voltage pulses corresponding to the elements in the different digital signals into reservoirs constructed by different quantities of virtual nodes, so as to extract signal features of the input signal in different quantization modes by the different reservoirs. By quantizing signals in different modes and inputting same into reservoirs constructed by different quantities of virtual nodes, the richness of internal states of the reservoirs can be improved, thereby further improving the signal identification accuracy of a reservoir system.

  • Patent number: 12660515
    Abstract: A three-dimensional reservoir based on three-dimensional volatile memristors and a method for manufacturing the same. In the three-dimensional reservoir, a memory layer, a select layer, and an electrode layer in each via form a memristor which is a reservoir unit. The three-dimensional reservoir is formed based on a stacking structure and multiple vias. The three-dimensional reservoir is constructed by using virtual nodes generated from dynamic characteristics of the three-dimensional memristors. An interfacial memristor is first constructed, and its volatility is verified through electric tests. A vertical three-dimensional array is manufactured based on the volatile memristor. A dynamic characteristic of the memristor is adjusted through a Schottky barrier. Different layers in the three-dimensional reservoir correspond to different reservoirs, which are constructed by controlling memristors in the different layers, respectively.

  • Patent number: 10062834
    Abstract: The present invention provides an electromagnetic conversion device, comprising: an intermediate layer and electrode layers located on both sides of the intermediate layer, wherein the intermediate layer is a magnetoelectric layer. The electromagnetic conversion device realizes the direct conversion of charge and magnetic flux, and thus can be used as a fourth fundamental circuit element, so as to provide a new degree of freedom for the design of electronic circuits and information function devices. In addition, the electromagnetic conversion device can be used as memory elements to form a nonvolatile magnetoelectric information memory.
