Abstract: A genetic algorithm controller that controls respective processes using a genetic algorithm is configured. The processes include generation of a crystal structure of an inorganic material, a mutation operation of a crystal structure, a crossing-over operation of a crystal structure, structural relaxation calculation of a crystal structure, calculation of a predictive value of an objective function, selection and weeding out of a crystal structure based on a predictive value of an objective function, observation of an objective function value of a crystal structure by first-principle calculation, update of a regression model based on a result of observing the objective function value, and end determination for a material generation process.

Abstract: To generate a prediction image in which an outline of an object is clear and existence of the object is easily recognized, the image prediction system that generates a future prediction image and includes a gaze unit, a working memory unit, a control unit, and a generation model unit. The gaze unit controls a region including an object included in an observation image as a first gaze region. The working memory unit controls the first gaze region as a second gaze region when a difference in the first gaze region between the observation image and a prediction image is equal to or less than a predetermined value. The generation model unit generates prediction images of the first gaze region and the second gaze region. The control unit integrates the prediction image of the first gaze region and the prediction image of the second gaze region to generate a prediction image.

Abstract: To provide a robust information processing system against attacks by Adversarial Example. A neural network model 608, a latent space database 609 for storing position information in a latent space in which first output vectors, which are output vectors of a predetermined hidden layer included in the neural network model, are embedded concerning input data used for learning of the neural network model, and an inference control unit 606 for making an inference using the neural network model and the latent space database are provided. The inference control unit infers the input data based on the positional relationship between the second output vector, which is an output vector of the predetermined hidden layer concerning input data to be inferred, and the first output vectors in said latent space.

Abstract: A cooperative autonomous control is implemented in consideration of emotions of a person or another apparatus. An apparatus holds an internal model for predicting a future state of an environment, acquires observation data indicating a state of an environment observed by the apparatus, generates first state information using the observation data, generates second state information of an intelligent agent present around the apparatus based on the first state information, decides a self emotion of the apparatus based on the first state information, decides a self emotion of the intelligent agent based on the second state information, decides a social emotion based on self emotions of the apparatus and the intelligent agent, generates future first state information and future second state information using the internal model, and decides an action based on the future first state information, the future second state information, and the social emotion.

Abstract: An information processing system includes a learning model unit, a trainer unit for allowing the learning model unit to learn, and a storage unit. The storage unit stores a validation rule defined in advance that indicates a condition determining that an output value of the learning model unit for an input value is true. The trainer unit inputs a plurality of input values to the learning model unit, obtains a plurality of output values of the learning model unit for the plurality of input values, determines whether each of the output values is true for each of the input values by referring to the validation rule, and stores a pair of an output data, which is determined to be true in the plurality of output values, and the corresponding input value into the storage unit, as new training data for supervised learning.
