Abstract: A training device comprises one or more memories and one or more processors. The one or more processors are configured to train a first converter that converts a first feature amount regarding a node of a graph and a second feature amount regarding a structure of the graph into a first latent value through conversion capable of defining inverse conversion, and a second converter that converts the second feature amount into a second latent value through conversion capable of defining inverse conversion, based on the first latent value and the second latent value.

Abstract: A training apparatus, for training a network, including a first network and a second network, configured to infer a feature of an input graph, includes memory and a processor. The processor is configured to: merge, by the first network, first hidden vectors of first nodes of the input graph and a second hidden vector of a second node coupled to each of the first nodes, based on the first hidden vectors, the second hidden vector, and information on coupling between the first nodes. The processor is further configured to update the first hidden vectors and the second hidden vector, based on a result of the merging; extract, from the second network, the feature of the input graph, based on the updated first hidden vectors and the updated second hidden vector; calculate a loss of the feature of the input graph; and update the first network or the second network.

Abstract: A timepiece dial plate comprises an upper plate (1) provided with holes (2, 4) and positioning legs (3) projecting from its lower surface so as to position the upper plate (1) relative to a movement; and a lower plate (11) provided on its upper surface with solid indices (12) to be fitted in the holes (2) of the upper plate (1) so as to protrude from an upper surface of the upper plate (1), and provided with holes (13) through which the positioning legs (3) of the upper plate (1) are extended. The upper plate (1) and the lower plate (11) are superposed so that the solid indices (12) of the lower plate (11) are fitted in the holes (2) of the upper plate (1), respectively, and protrude from the upper surface of the upper plate (1), and the positioning legs (3) of the upper plate (1) extend through the holes (13) of the lower plate (11), respectively.
