Abstract: A server includes a distribution difference calculator and a determining unit. The distribution difference calculator calculates difference information between a first distribution of features calculated from operating data of terminal devices of a first machine type and a second distribution of features calculated from operating data of terminal devices of a second machine type. The determining unit determines whether a model is applicable to the terminal devices of the first machine type to predict occurrence possibility of a failure in each terminal device of the first machine type on basis of the difference information wherein the model is generated on basis of operating data of the terminal devices of the second machine type and is configured to predict occurrence possibility of a failure in each terminal device of the second machine type on basis of each of the features calculated from the operating data thereof.

Abstract: In a model parameter calculation device, the comparator compares a first evaluation value calculated from a first model and operating data on a terminal device with a second evaluation value calculated from a second model and the operating data. The requester transmits an inspection request to inspect the terminal device to the terminal device or a management device thereof in accordance with a comparative relation between the first evaluation value and the second evaluation value. The parameter determiner determines a third parameter included in a third model in accordance with a model reference of a predefined model type, on basis of an inspection result indicating an operating status of the terminal device and the operating data of the terminal device, wherein the third model associates the third parameter with a third output variable regarding the occurrence possibility of the failure in the terminal device.

Abstract: An apparatus for determining a contour of a treatment region in a patient includes a computer processor to receive input regarding a contour of at least one organ-at-risk (OAR) adjacent to the treatment region; receive input regarding an initial contour of the treatment region; predict a radiation toxicity to the at least one OAR based on the contour of the at least one OAR, the initial contour of the treatment region, and a radiation treatment regimen; determine whether the predicted radiation toxicity exceeds a threshold; and determine a contour of the treatment region by iteratively modifying the initial contour of the treatment region, and any subsequent modified contours of the treatment region, until a stopping condition is satisfied. The stopping condition can be a preselected number of iterations or that the predicted radiation toxicity using the contour in place of the initial contour is first calculated is below said threshold.
