Abstract: A reservoir computing data flow processor includes a plurality of reservoir units to be units constituting a reservoir. The reservoir is able to be reconfigured by changing a connection relationship between the reservoir units. Each of the reservoir units is an operation unit block configured to execute a predetermined operation. The operation unit block includes a first adder configured to perform an addition operation on at least two inputs, a nonlinear operator configured to apply a nonlinear function to an output from the first adder or a result of multiplying the output by a predetermined coefficient, and a second adder configured to perform an addition operation on at least two inputs including an output from the nonlinear operator or a result of multiplying the output by a predetermined coefficient.

Abstract: The node includes a first input terminal, a second input terminal, a first sample and hold circuit, and a first output terminal. The first input terminal is configured to be connectable to an input source for transmitting an input signal to a reservoir device. The second input terminal is configured to be connectable to at least one other node. A first terminal of the first sample and hold circuit is connected to the first input terminal and the second input terminal. A second terminal of the first sample and hold circuit is connected to the first output terminal. The first output terminal is configured to be connectable to at least one other node. The first sample and hold circuit holds and converts a joined signal of the input signal and a propagated signal from the second input terminal.
