Abstract: According to one embodiment, a quantum key delivery service platform includes a plurality of quantum key delivery devices and a management server. The server monitors a storage amount of the encryption keys in the plurality of quantum key delivery devices, records a consumption record of the encryption keys for each of the plurality of cryptographic communication devices, predicts a consumption amount of the encryption keys based on the consumption record of the encryption keys, and detects a sign of shortage of the encryption keys based on the storage amount of the encryption keys and a prediction result of the consumption amount of the cryptographic keys.

Abstract: An information processing device includes a definer, a determiner, and a reinforcement learner. The definer is configured to associate a node and an edge with attributes and to define a convolution function associated with a model representing data of a graph structure representing a system structure on the basis of data regarding the graph structure. The evaluator is configured to input a state of the system into the model. The evaluator is configured to obtain, for each time step, a policy function as a probability distribution of a structural change and a state value function for reinforcement learning for a system of one or more structurally changed models which have been changed with assumable structural changes from the model for each time step. The evaluator is configured to evaluate the structural changes in the system on the basis of the policy function.

Abstract: An information processing device of embodiments includes a data acquirer and a network processor. The data acquirer is configured to acquire graph structure data that includes a plurality of real nodes and one or more real edges connecting two of the plurality of real nodes. The network processor is configured to execute processing of propagating a feature amount of a k?1th layer of each of a plurality of assumed nodes that include the plurality of real nodes and the one or more real edges at least to a feature amount of a kth layer of another assumed node in a connection relationship with each of the assumed nodes in a neural network on the basis of the graph structure data acquired by the data acquirer. k is a natural number equal to or more than 1.

Abstract: A system and method for allocating an incoming call to a desired one of a plurality of destination candidates in response to data in at least one predetermined category concerning a caller, e.g. the area, the company or the department of the caller (a source address mode). There may be other modes such as a direct in line (DIL) mode and global mode. When a call is received by one of trunk circuits, the termination mode for the call is set for one associated with the trunk circuit that received the call. In case of the source address mode, the call is allocated to one of the destination candidates which is associated with the caller number or a part thereof. An association between a caller number (a part thereof) and a destination candidate is preferably achieved using a destination information table containing at least such information.

Abstract: An electronic exchange apparatus which is maintained by remote control based on information supplied from a maintenance terminal through a communications network, comprises a memory for storing called party number information representing a number for maintaining the electronic exchange apparatus and calling party number information representing a number of the maintenance terminal for allowing a maintenance operation, and a controller for, when a call is received from the communications network, detecting whether called party number information and calling party number information included in a message transmitted together with the call, coincide with the called party number information and the calling party number information stored in the memory, respectively, and for, when the information included in the message coincides with the information stored in the memory, recognizing the call as a maintenance call for maintaining the electronic exchange apparatus, thereby setting the electronic exchange apparatus
