  • Publication number: 20230368040
    Abstract: An online probabilistic inverse optimization system 10 is proposed for inferring objectives and constraints in an online fashion from changing problem data and corresponding agent decisions. The online probabilistic inverse optimization system 10 includes: a computing unit 11 which computes optimal solutions or decisions based on the forward optimization problem using the problem data that may include objectives, constraints and parameters; and a solving unit 12 which solves the inverse optimization problem using the agent decisions.

  • Patent number: 11579574
    Abstract: A control customization system 80 customizes a plant control. A profiler 81 predicts actions of a user depending on situations of the plant or the user. A planner 82 determines an appropriate set of objectives which represent tasks desired by the user, and objective terms representing elements for controlling the plant so as to realize the objectives, and tunes the objective terms based on predictions of the profiler 81.

  • Publication number: 20220400312
    Abstract: An input of a constraint parameter associated with a constraint required when optimizing a target is received. An objective function to be utilized for the optimization of the target is computed by using optimized results by an expert who has performed the optimization in the past, the constraint parameter, and an inverse optimization technique. The target is optimized based on the objective function.

  • Patent number: 11435705
    Abstract: An expert model unit 81 generates predicted expert control actions based on an expert model which is a machine learning model trained using data collected when an expert operated a plant which is a control target or a plant of the same or similar characteristics. A transformer 82 constructs metrics or error measures involving the predicted expert control actions from the expert model unit 81 as an objective term. A combiner 83 collects different objective terms from the transformer 82 and a learner which outputs machine-learning models as objective terms and computes an optimal set of weights or combinations of the objective terms to construct an aggregated cost function for use in an optimizer.

  • Patent number: 11400954
    Abstract: A vehicle control system for controlling driving of a vehicle reflecting an environment and a characteristic of a user, while suppressing increase in learning time, is provided. The vehicle control system includes classification means for classifying, by using one or more attributes selected from accumulation means for accumulating data including attributes relating to driving of a vehicle, driving properties included in the data, learning means for learning a model representing the driving property, for each of types that are a result of classification by the classification means, and control information determination means for determining, by using the model learned for the type associated with a value of the attribute at time of driving of a control target vehicle, control information for the driving.

  • Patent number: 11398113
    Abstract: A toll control apparatus 100 includes a traffic volume prediction unit 10 that predicts a future overall traffic volume on a first road 401 and a second road 402, a toll control unit 20 that outputs, with the predicted overall traffic volume and a predetermined road toll as inputs, a future traffic volume and a predicted traveling speed on the second road for a case where a toll on the second road is set to the predetermined road toll, and a toll optimization unit 30. The toll optimization unit 30 sets one or more road toll candidates, selects a road toll candidate for which the predicted traveling speed obtained by inputting the road toll candidate to the toll control unit 20 is greater than or equal to a threshold value, and sets the road toll candidate that maximizes the toll revenue for the second road among the selected road toll candidates.

  • Publication number: 20200249637
    Abstract: An ensemble control system 80 combines different types of plant control. A plurality of subcontrollers 81 output actions for the plant control based on a prediction result by a predictor. A combiner or switch 82 combines or switches actions to maximize prediction or control performance as best control action based on the actions output by each subcontroller 81. Subcontrollers 81 include at least two types of subcontrollers. A first type subcontroller is an optimization-based subcontroller which optimizes an objective function that is a cost function to be minimized for calculating actions and outputs a control action. A second type subcontroller is a prediction-subcontroller which predicts based on machine learning models and outputs a predicted action.
