Abstract: Provided are an information selection system, an information selection method, and an information selection program for efficiently and appropriately selecting information for use in information processing. A control unit of an assistance server generates a plurality of analysis models, using one or more pieces of information among information constituted by a plurality of pieces of training data, and calculates the accuracy of each of the analysis models. The control unit assigns distribution values according to each accuracy to information used for generating the analytical models, calculates statistics of the distribution values, for each piece of information used for generating the analytical models, and selects, using the statistics, information for use in generating the analytical models.

Abstract: A control unit of a support server identifies, with respect to input data, a nearby node among existing nodes. The control unit calculates the distance between the input data and the nearby node. If the distance is greater than a maximum distance, the control unit uses the input data to add a new node to the existing nodes, and updates the activity value and the age of the new node and the nearby node in accordance with the distance to the nearby node. The control unit generates a self-organizing map by using the activity value of each node and the activity value of each path to calculate an age-based degree of activity, and by determining the presence or absence of each node and each path according to the degree of activity.

Abstract: A support apparatus includes an irradiation device for emitting a particle beam, a detection device for detecting a particle beam irradiation region, and a control unit for acquiring the irradiation region. The control unit specifies an attention region within the irradiation region in a treatment plan for a patient, and specifies the irradiation position for pre-irradiation within the attention region. The control unit instructs the irradiation device to carry out pre-irradiation with irradiation energy in the treatment plan at the irradiation position, and acquires the irradiation region detected by the detection device. The control unit further adjusts irradiation conditions in the treatment plan according to the irradiation region in the pre-irradiation and instructs the irradiation device to carry out post-irradiation under the adjusted irradiation conditions.
