Abstract: The combine may include a threshing tank that is configured to store a threshing product obtained by the threshing device and includes a lower tapered portion formed in a bottom portion. A bottom screw is provided inside the lower tapered portion and configured to discharge the threshing product from the threshing tank. A threshing discharge device is connected to the bottom screw and configured to convey the threshing product from the bottom screw and discharge the threshing product in a body outward direction. The threshing tank includes an inspection port formed in a bottom section of the lower tapered portion, and a lid configured to open and close the inspection port, and the lid opens and closes by swinging upward and downward about a swing axis that is not parallel with a screw axis of the bottom screw.

Abstract: A non-transitory computer-readable recording medium stores a program for causing a computer to execute a process that includes acquiring a dataset without including correct answer data, generating a first constraint condition used to maximize mutual information between each data point included in the dataset and a class label assigned to the each data point, generating a second constraint condition that reduces a distribution distance regarding class labels assigned to two data points between which a Euclidean distance is closer than a predetermined value, generating a third constraint condition that reduces a distribution distance regarding class labels assigned to data points estimated to have a same class label, and increases a distribution distance regarding class labels assigned to data points estimated to have different class labels, and training a neural network that performs data classification, by performing optimization processing based on the first, second, and third constraint conditions.
