    Abstract: Provided is a reservoir computing system that is miniaturized and has a reduced learning cost. The reservoir computing system uses a reservoir that includes a first optical output section that outputs a first optical signal; a first optical waveguide that propagates the first optical signal output by the first optical output section; an optical receiving section that receives the first optical signal from the first optical waveguide; a storage section that stores received optical data corresponding to the first optical signal and output by the optical receiving section; and a feedback section that applies, to the first optical signal, feedback corresponding to the received optical data stored in the storage section.

    Abstract: A receptor of wireless signal in a wireless communication system can be configured to correct for degradations of signal quality. The reception apparatus can include a filter which is configured to create a filtered signal by make corrections to a reception signal which carries a symbol. Based on the created filtered signal, a symbol can be decided and weighted to evaluate the error of the original reception signal. Using the weighting information, a parameter of the filter can be updated to more accurately correct the reception signal.

    Abstract: A plurality of chips arranged in a certain layout so as to face free space, and one or more optical elements are included. In the case where signal traffic for electrical communication with a given chip exceeds or is expected to exceed a certain threshold, a plurality of chips involved in communication routing of the excess signal traffic are identified, part of related signal traffic that crosses the plurality of identified chips is converted from an electric signal into an optical signal to re-route the excess signal traffic, and paths of the related signal traffic are dynamically adapted from fixed wired paths between the plurality of chips to optical communication paths formed in the free space.

    Abstract: To realize a reservoir computing system easily implemented as hardware, provided is a reservoir computing system including a reservoir operable to output an inherent output signal in response to an input signal. An input node is operable to supply the reservoir with an input signal corresponding to input data, and an output node is operable to output an output value corresponding to an output signal that is output by the reservoir in response to the input data. An adaptive filter is operable to output output data based on a result obtained by weighting a plurality of the output values output from the output node at a plurality of timings with a plurality of weights. Also provided are a learning method and a computer program product.
