Abstract: There is provided a mini-batch learning apparatus that learns a machine learning model for performing semantic segmentation, which determines a plurality of classes in an image in units of pixels, by inputting mini-batch data to the machine learning model, the apparatus including a calculation unit, a specifying unit, and a generation unit. The calculation unit calculates, from a learning input image and an annotation image which are sources of the mini-batch data, a first area ratio of each of the plurality of classes with respect to an entire area of the annotation image. The specifying unit specifies a rare class of which the first area ratio is lower than a first setting value. The generation unit generates the mini-batch data from the learning input image and the annotation image. The generation unit generates the mini-batch data in which a second area ratio of the rare class is equal to or higher than a second setting value higher than the first area ratio calculated by the calculation unit.

Abstract: In a case where the operation program is started, a CPU of the mini-batch learning apparatus functions as a calculation unit, a specifying unit, and an evaluation unit. The calculation unit calculates an area ratio of each of a plurality of classes in mini-batch data. The specifying unit specifies, as a correction target class, a rare class of which the area ratio is lower than a setting value. The evaluation unit evaluates the class determination accuracy of the machine learning model by using a loss function. As correction processing, the evaluation unit sets a weight for a loss value of the rare class to be larger than a weight for a loss value of a class other than the rare class.

Abstract: Provided are an imaging device, an imaging method and an imaging control program which make it possible to shorten an imaging time, and to capture an image of each observation region at an appropriate focusing position regardless of the state of installation of a culture vessel on a stage. In a case where an observation target is imaged multiple times, a focusing position of an observation region within a culture vessel is detected by auto-focus control during first imaging, and the first imaging of each observation region is performed using the focusing position. Next, the focusing position of a reference position is detected by auto-focus control during second imaging subsequent to the first imaging, and the focusing position of each observation region detected in the first imaging is corrected on the basis of the detected focusing position and the focusing position of the reference position in the first imaging.
