Abstract:
A data classification method and a device thereof for hierarchical multi-label classification are proposed. The data classification device includes an encoder configured to vectorize data, a decoder configured to receive the vectorized data from the encoder, and classification data stored in the decoder, wherein the decoder starts classification of the vectorized data on the basis of a first node in the classification data, allocates a plurality of nodes included in the classification data to the vectorized data, and forms partial layers based on the allocated nodes with respect to the vectorized data, and when terminal nodes or temporary nodes are allocated among the nodes, the decoder ends the allocation to the partial layers to which the terminal nodes or the temporary nodes are allocated and allocates final partial layers formed on the basis of the partial layers to the data.
Abstract:
Disclosed is an interaction system between a controller and a VR application. The interaction system includes a controller including a first actuator configured to move a mass and a first processor configured to control an operation of the first actuator; and a content execution device configured to execute an application according to a control signal received from the controller and generate a feedback signal to transmit the generated feedback signal to a controller when a virtual object change event occurs during the application execution, wherein the first processor of the controller controls the first actuator when the feedback signal is received to move the mass and move a center of gravity. According to the present disclosure, since the center of gravity and the length of the controller operated by the user in reality may be changed in linkage with a change of the virtual object displayed on the display while executing the VR application, it is possible to greatly improve the immersion and feeling of use of the user.

Abstract:
A skyline query is a query on a set of tuples which are not dominated by other tuples. The skyline query system includes a sky quad tree generator that generates a quad tree from data, and marks a leaf node, which cannot include a local skyline, as being dominated; a local skyline calculator that computes a local skyline of each leaf node, which is not marked as being dominated, in the sky quad tree; and a global skyline calculator that computes a global skyline by using the local skyline. A quad tree is a tree where each internal node has exactly four children. The skyline query is a query for calculating a skyline, a dynamic skyline, or a reverse skyline from the data, where a dynamic skyline includes dynamic attributes and a reverse skyline identifies queries corresponding to certain skyline results.
