  • Publication number: 20210271924
    Abstract: An analyzer calculates a first feature amount data group from an intermediate layer by inputting each training data of a training data group into a learning model which includes an input layer, one or more intermediate layers, and an output layer, and is learned based on the training data group assigned to the input layer and a correct answer data group assigned to the output layer. A second feature amount data is calculated from the intermediate layer by inputting prediction target data of the learning model. A search processing of searching specific first feature amount data similar to the second feature amount data is calculated by the second calculation processing, from the first feature amount data group, and an extraction processing of extracting, from the training data group, specific training data, which is a calculation source of the specific first feature amount data searched by the search processing.

  • Patent number: 10699814
    Abstract: The task is to provide a system which supports smooth patient referral from a referral source medical institution to a referral destination medical institution and which particularly prevents readmission due to cases that are difficult to determine simply based on patient attributes or due to the quality of medical services. To achieve this task, a referral difficult degree calculation unit calculates a referral difficulty degree which quantifies the risk that a patient cannot be discharged because a referral destination cannot be found, in consideration of a readmission risk calculated by a readmission risk calculation unit, the geographical distance between the patient and the referral destination medical institution, the total number of patients accepted, and the number of beds available. This referral difficulty degree is outputted to an output unit of the referral source medical institution or the referral destination medical institution.

  • Patent number: 9292762
    Abstract: Provided is a region extraction system that uses an image data analysis process, which has overcome the problem of false positives in region extraction and assists in more accurate region extraction. A luminance distribution-analyzing unit (105) is used to determine a parameter of unknown quantity for extracting a region of interest. The luminance distribution-analyzing unit (105) searches a luminance distribution management database (106) for a region, which has a luminance distribution similar to the region of interest and is easily extracted, as a similar area. The region of the similar area is extracted using a region extraction pre-processing unit (107) and the value of the parameter of unknown quantity is determined on the basis of an image feature value calculated from the region extraction results.

  • Publication number: 20140344274
    Abstract: The present invention periodically and exhaustively extracts analysis dimension candidates from text data, such as medical literatures disclosed on the Internet. A name of disease, a medical agent, a checkup, and an operation included in actual clinical data are linked to the analysis dimension candidates. In the analysis dimension candidates, clinically important candidates and non-important candidates including extraction errors are mixed. To distinguish the candidates, weighting is provided to the link. First, a weight is made large when a level of an evidence of a medical literature from which an analysis dimension candidate is extracted is high. In literature groups of each name of disease, the degree of cooccurrence between a word of an analysis dimension candidate, and a word related to a medical agent/checkup/operation is calculated, and the weight of the link is made larger according to the magnitude of the degree of cooccurrence.

  • Publication number: 20140153833
    Abstract: The present invention relates to a technology for extracting a target area from within an image by a combination of a plurality of image processes, enabling an automatic setting of an image process procedure without an operator inputting the image process procedure. Thus, according to the present invention, the content of an image process to be carried out in the next and subsequent rounds is automatically determined based on a history of results of image processes that have been applied to a process object image up to the immediately preceding round.
