  • Publication number: 20230065173
    Abstract: To infer a value of an assignment variable with high accuracy. In a causal relation inference device including a processor configured to execute a program and a storage device storing the program, the processor is configured to execute a first calculation process of calculating an internal vector based on a feature vector of a plurality of samples and a first learning parameter, a second calculation process of calculating a reallocation vector based on a second learning parameter and the internal vector calculated by the first calculation process, and a third calculation process of calculating a pointwise weight vector for each of the plurality of samples based on a third learning parameter and the reallocation vector calculated by the second calculation process.

  • Publication number: 20210074428
    Abstract: A data processing apparatus includes: a storage section storing an object-to-be-analyzed data group having factors and an objective variable per object to be analyzed; a first modulation section modulating a first factor and outputting a first modulation result per object to be analyzed; a second modulation section modulating a second factor and outputting a second modulation result per object to be analyzed; and a generation section that assigns, per object to be analyzed, a coordinate point representing the first modulation result from the first modulation section and the second modulation result from the second modulation section to a coordinate space specified by a first axis corresponding to the first factor and a second axis corresponding to the second factor, and that generates first image data obtained by assigning information associated with the objective variable of the object to be analyzed corresponding to the coordinate point to the coordinate point.

  • Patent number: 10795343
    Abstract: A data providing apparatus includes a field data acquisition unit configured to acquire field data relating to field equipment, and a data providing unit configured to transmit and receive information to and from a service providing unit, the service providing unit being a communication target and configured to use the field data as service data, in which the data providing unit manages information on a conversion rule defining a relationship between the field data and the service data, acquires the field data specified in a data acquisition request from the service providing unit, from the field data acquisition unit, converts the acquired field data to service data according to the conversion rule when there is a difference between a specification of the field data and a specification of the service data, and transmits the data obtained by the conversion to the service providing unit.

  • Publication number: 20050213551
    Abstract: In a conventional method of organizing image data taken by a digital camera, only information on the date and time and position are attached to each data, without acquiring information related to the content of the data. Therefore, positional information is obtained and attached to the data of image or text, and when storing the data, information related to the position is acquired based on the positional information and stored in association with the data. Related information is also acquired when the data is viewed. The size of a data file is reduced with a decreased size of information attached to the file. Acquiring the latest information as well as previous information upon viewing the data is possible, since information related to the position of data creation is available in addition to information on the date and time and position, when storing and viewing the data. The acquired information enables detailed categorizing, searching and rendering of data.
