  • Patent number: 11836906
    Abstract: An object of the present invention is to achieve both suppression of data amount of an image processing system that learns a collation image to be used for image identification using a discriminator and improvement of identification performance of the discriminator. In order to achieve the above object, there is proposed an image processing system including a discriminator that identifies an image using a collation image, the image processing system further including a machine learning engine that performs machine learning of collation image data required for image identification. The machine learning engine searches for a successfully identified image using an image for which identification has been failed, and adds information, obtained based on a partial image of the image for which identification has been failed and which has been selected by an input device to the successfully identified image obtained by the search to generate corrected collation image data.

  • Publication number: 20170307480
    Abstract: To improve diagnostic accuracy in diagnosing for abnormality of a machine, it is necessary to adjust a parameter regarding diagnosis such as the number of clusters. In such an adjustment operation, each time a diagnostic parameter is modified, a checking operation by an analysis operator is required to see whether a diagnosis result has been improved. The present invention assists in the checking operation to see whether diagnostic accuracy has been improved by comparing diagnosis results before and after parameter modification. If there are many items of sensor data for diagnosis, many items of abnormality degree data arise as analysis result. Many items of data pose a problem that comparing diagnosis results takes time. In the data display system, abnormality degree data that has changed largely before and after parameter modification is automatically found and displayed to the analysis operator. How much an abnormality degree has changed is determined as an abnormality degree change rate, i.e.

  • Publication number: 20050278248
    Abstract: Simulation for evaluating approval/rejection of an action plan of the type in which work breakdown struction is changed by influences of external risk factors is achieved. A simulation apparatus includes a plan/risk input portion for accepting input of action plan data and risk scenario data, a plan/risk simulation portion for conducting simulation of an action plan by using the action plan data and the risk scenario data so accepted, and a plan evaluation output portion for evaluating a simulation result. The plan/risk simulation portion simulates occurrence of a risk phenomenon by using the risk scenario data, determines influence information given by the risk phenomenon to the action plan when the risk phenomenon is simulated as occurring and conducts simulation of the action plan by reflecting the influences of the risk scenario on the action plan by using the influence information so determined.
