摘要： A learning device generates a first learned model by subjecting a learning model to learning such that a correlation coefficient between a first explanatory variable for learning and an explained variable output from the learning model is maximized when the learning model that outputs an explained variable in a case where an explanatory variable is input is subjected to learning on the basis of first learning data representing a pair of the first explanatory variable for learning and a first explained variable for learning. When the first learned model is subjected to relearning on the basis of the second learning data representing the pair of the second explanatory variable for learning and the second explained variable for learning, the learning device generates the second learned model by subjecting the first learned model to relearning such that the error between the second explained variable for learning and the explained variable output from the first learned model is minimized.

摘要： A three-dimensional point group is accurately identified on the basis of GIS data in which a geographical position of an object is defined by a polygon, a line, or a point.
An initial label assignment unit (101) assigns a label indicating an object or a type of the object corresponding to some three-dimensional points included in a three-dimensional point group to the three-dimensional points on the basis of GIS data indicating a geographical position of the object by a polygon formed by connecting a plurality of coordinate points, a line formed by connecting a plurality of coordinate points, or one coordinate point itself, and an estimation unit (112) estimates a label of three-dimensional points to which the label has not been assigned by propagating the label of the three-dimensional points to which the label has been assigned to the three-dimensional points to which the label has not been assigned based on similarity between the three-dimensional points to which the label has been assigned and the three-dimensional points to which the label has not been assigned.

摘要： An update control device of a container-based cluster update system constructs a master node in a new container-based cluster and constructs a minimum number of worker nodes required to execute a migration target application. The update control device deletes a migration target application of a container-based cluster in an initial state, deletes a worker node in which no application is installed, adds the worker node to a new container-based cluster, and sequentially migrates the migration target application to perform update.

摘要： A cumulative calculation device according to an embodiment is a cumulative calculation device that, with respect to a column v=(v1, . . . , vn) of n values divided into groups, calculates cumulation for each of the groups through an associative binary operation. The cumulative calculation device includes: a value conversion unit configured to convert v into v′=(v1′, . . . , vn′) (where v1′=(v1, ci)) when c=(c1, . . . , cn) is a column of values in which 1 corresponds to a head element of the group and 0 corresponds to elements other than the head element among elements v1, . . . , vn of v; a binary operation generation unit configured to generate a new binary operation for calculating a new pair (p, q) for two pairs (w, x) and (y, z) (where x, z ∈ {0, 1} using the binary operation; a cumulative calculation unit configured to calculate cumulation s1′ (where si′ is cumulation from v1′ to vi′ from the new binary operation) by the new binary operation for i=1, . . . , n; and an output unit configured to extract a column u=(u1, . . . , un) of values indicating the cumulation for said each of the groups from each si′ (where i=1, . . . , n) and output the extracted u.
The new binary operation sets an operation result of w and y by the binary operation to p when z=0, sets y to p when z=1, and sets a logical sum of x and z to q.

摘要： A temperature regulating unit is attached to a first incident surface of a first component through a first transparent electrode. The temperature regulating unit is composed of a Peltier element. The temperature regulating unit includes an opening through which the target light can pass. The temperature regulating unit has, for example, a rectangular parallelepiped outer shape in which a surface perpendicular to an optical axis is square-shaped. The opening is formed to penetrate through the temperature regulating unit in a direction perpendicular to the optical axis and has a circular shape in a plan view.

摘要： A storage unit stores a size of a free area of storage of target equipment, and software saved in the storage. The generation unit generates a graph including a number of nodes according to the size of the free area of the storage, and transmits the graph to the target equipment. The calculation unit calculates a hash value corresponding to each software block saved in the storage. The verification unit verifies the presence or absence of tampering of the storage of the target equipment using the hash value corresponding to the block calculated, a response calculated using the graph returned to a challenge that specifies a node of the graph, and a hash value corresponding to the block returned as the response to the challenge that specifies the block.
