  • Publication number: 20250068669
    Abstract: A document search system that enables efficient document search regardless of the ability of a user is achieved. Document search is performed using a document search system in which database document data is stored. After first document data and second document data are input to the document search system, the document search system extracts a plurality of terms from the first document data. The extraction of the terms is performed using morphological analysis, for example. Next, the extracted terms are weighted on the basis of the second document data. For example, texts included in a document represented by the second document data are classified into first and second texts. Among the terms extracted from the first document data, the weight of the term included in the first text is set larger than the weights of the other terms. The classification of the texts can be performed in accordance with a rule basis or using machine learning.

    Abstract: A construction method of a trained model includes six processes. In a first process, data for performing machine learning of an operation of a controlled machine by a human is collected. In a second process, collected data that is the data collected is evaluated and, when it does not satisfy a predetermined evaluation criterion, the data is collected again. In a third process, training data is selected from the collected data that satisfies the evaluation criterion. In a fourth process, the training data is evaluated and, when it does not satisfy a predetermined evaluation criterion, the training data is selected again. In a fifth process, a trained model is constructed by machine learning using the training data that satisfies the evaluation criterion. In a sixth process, the trained model is evaluated and, when it does not satisfy a predetermined evaluation criterion, the trained model is trained again.

  • Patent number: 12012493
    Abstract: A composite semipermeable membrane capable of forming, on a surface of a porous support in a highly reproducible manner, a separation layer that is extremely thin and that exhibits superior separability. It provides, on a surface of a porous support, a composite semipermeable membrane that has an organic/inorganic hybrid separation layer that is extremely thin and that exhibits superior separability. A method for manufacturing a composite semipermeable membrane includes forming, on a surface of a porous support, a separation layer containing a cross-linked condensate having a siloxane bond by bringing an organic solution that contains an organic silicon compound containing three or more reactive functional groups, each of which is at least one type selected from a hydrolyzable group and a hydroxyl group, into contact with water or an aqueous solution on the porous support, and by performing interfacial polycondensation of the organic silicon compound.

  • Patent number: 11967101
    Abstract: The present invention provides a motion capture with a high accuracy which can replace an optical motion capture technology, without attaching optical markers and sensors to a subject. A subject with an articulated structure has a plurality of feature points in the body of the subject including a plurality of joints wherein a distance between adjacent feature points is obtained as a constant. A spatial distribution of a likelihood of a position of each feature point is obtained based on a single input image or a plurality of input images taken at the same time. One or a plurality of position candidates corresponding to each feature point are obtained based on the spatial distribution of the likelihood of the position of each feature point. Each join angle is obtained by performing an optimization calculation based on inverse kinematics using the candidates and the articulated structure.
