Abstract: A training device updates, among a plurality of models, a model for a region that includes a given sample based on the sample. The plurality of models are provided for each region obtained by dividing a state space that includes a sample indicates a state about a control object and the plurality of models represent an evaluation of an action of the control object in response to control over the control object. The training device evaluates an action of the control object in a given state, based on a model for a region that includes a sample indicating the state.

Abstract: An information processing device acquires training data. The training data includes time-series data of a measurement item regarding a target and time-series data of an item that influences the target. The information processing device trains, by using the training data, a model that receives an input of time-series data of the measurement item and outputs time-series data of the item that influences the target.

Abstract: An inference device performs a qualitative inference using an inference rule which, from an input of a value indicating an increase and a value indicating a decrease, derives an output representing any one of an increase, a decrease, or no change.

Abstract: A learning device includes at least one memory configured to store instructions; and at least one processor configured to execute the instructions to: perform reinforcement learning of control over a control target; use data used in the reinforcement learning to learn a model that shows the relationship between a state relating to the control target, control over the control target, and a temporal change in the state relating to the control target; and use the model and the result of the reinforcement learning to learn control over the control target.

Abstract: A text processing system that is able to appropriately determine textual entailment between sentences with high coverage is provided. The text processing system is configured to execute: processing of extracting a common substructure that is a partial structure of a same type, the partial structure being common to a first sentence and a second sentence and, based on the a structure representing the first sentence and a structure representing the second sentence; processing of extracting at least one of a feature amount representing a dependency relationship between the at least one common substructure in the first and second sentences and a feature amount representing a dependency relationship between the common substructure in the first and second sentences and a substructure different from the common substructure; and processing of determining an entailment relationship between the first sentence and the second sentence by using the extracted feature amount.

Abstract: A setting device sets a parameter value of a simulator that simulates a simulation subject. The setting device calculates weights of respective output items based on an output value of the simulator and a reference output value. The reference output value is subject to simulation according to the output value of the simulator. The setting device controls, by using an evaluation function, learning of a setting of a parameter value of the simulator. The evaluation function is based on the output value of the simulator, the reference output value, and the weights.

Abstract: An estimation device determines a state estimation target portion of a monitoring target based on qualitative inference that uses designated portion qualitative expression information qualitatively indicating a state of a designated portion of the monitoring target, and acquires state candidate qualitative expression information that qualitatively indicates a candidate for the state of the state estimation target portion. The estimation device acquires state candidate quantitative expression information that quantitatively indicates a candidate for the state of the state estimation target portion, based on the state candidate qualitative expression information.

Abstract: An inference device makes an inference in accordance with first-order predicate logic by using: a true or false of a proposition that determines a state of a target by using a predicate that represents the state of the target; and an inference rule where a predicate representing a state of a target in an antecedent differs from a predicate representing a state of a target in a consequent. The predicate representing the state of the target in the antecedent and the predicate representing the state of the target in the consequent represent a proposition that determines a state of a target in a different time step.
