  • Patent number: 11475373
    Abstract: A retail agent determines a parameter of an activity proposal model by using data stored in a past record database, and determines parameters of an activity determination model and an activity value evaluation model by further using base activity simulation data. Consequently, it is possible to appropriately determine parameters of a subsystem control method in a complex system which cannot be embodied as a simulator and shows a significant change with respect to past record data.

  • Publication number: 20200303042
    Abstract: To predict a new biological reaction by quantifying while retaining characteristics of an entire compound structure. To provide a structural characteristic amount encoding unit that includes a conversion model unit configured to convert a characteristic amount of notation information indicating chemical structures of a plurality of compounds into a dispersedly represented numerical vector having at least two or more real number values as an element using a conversion parameter, the conversion model unit converting the characteristic amount of the notation information indicating the chemical structures into a numerical vector, for each of a first compound and a second compound among the plurality of compounds, and a biological reaction characteristic vector generator configured to generate a biological reaction characteristic vector between the first compound and the second compound by performing a calculation using a numerical vector of the first compound and a numerical vector of the second compound.

  • Patent number: 10768583
    Abstract: A learning control system is provided in each of a plurality of subsystems of a system and includes a plurality of agents that performs learning to control of the subsystem using a control model and a learning management agent that manages and controls learning of each of the plurality of agents. The learning management agent is operated with a plurality of experiment systems including the plurality of control model sets of the plurality of agents and determines a plurality of updating control model sets in the plurality of experiment systems of a next generation from an evaluation result of the plurality of experiment systems of the current generation. The agent transmits control model information of a current generation to the learning management agent and receives control model information of the next generation from the learning management agent.

  • Publication number: 20180181089
    Abstract: A control device that determines an output value of an actuator based on an input value of a sensor, includes a control unit that includes a control model capable of changing a parameter; a control unit that includes a control model fixed in a parameter acquired by a different device; and an action selection unit that selects an output value from output values of the respective control units and outputs the selected output value to an actuator, and determines an output value of the actuator, based on an input value from a sensor of a machine.

  • Patent number: 9802310
    Abstract: A robot is provided. A measurement unit measures an object in a space. An own-position estimation unit calculates an own position of a mobile unit moving through the space by matching measurement data acquired by the measurement unit with map data representing information about the object in the space. A classification unit acquires class-based measurement data obtained by classifying the measurement data into at least two predetermined classes. A class-based own-position estimation unit estimates an own position of the mobile unit for each of the at least two predetermined classes by matching a class-based map having a position of the objects recorded therein for each class with the class-based measurement data. An integration unit configured to integrate the own positions estimated for the respective at least two predetermined classes. A control unit controls the mobile unit based on information from the integration unit.
