Latest Patents

One of his latest patents is a "Computer system and model training method." This invention provides a computer system for generating a neural network (NN) used for various tasks. It includes a training unit that calculates a weighting factor between a reservoir and an output layer using training data. Additionally, it features a first storage unit that stores node activity information and a second storage unit for model information. When a training execution request for a second task is received after completing the first task, the training unit calculates a weighting factor for the NN used for a third task, updates the model information, and adjusts the node activity information based on the training process of the third task.

Another notable patent is the "Computing system and method," which enhances the computing performance of a system using reservoir computing (RC). This technology includes a computing system that performs computations using a recurrent neural network (RNN) with an input unit, a reservoir unit, and an output unit. The reservoir unit consists of multiple nodes connected in a circular manner, with a weight matrix determining the weights between the nodes. Each node has a g value that designates the nonlinearity of its activation function, which periodically changes direction on the circle.
