Abstract: There is provided a method for predicting a user personality by mapping multimodal information on a personality expression space. A personality prediction method according to an embodiment extracts a multimodal feature from an input image in which a user appears, maps the extracted multimodal feature on a personality expression space, and predicts a personality of the user based on a result of mapping. Accordingly, a personality of a user may be more exactly predicted through establishment of a correlation between user's various behavior characteristics and personalities.

Abstract: An adaptive batch processing and apparatus is proposed. The adaptive batch processing method may be performed by a system including a server which saves a model trained by machine learning and a client which transmits input data by connecting to the server while requesting an analysis result based on the model for the corresponding input data. The method may include measuring an amount of available resources of the server in the server, calculating a batch size using the amount of the available resources measured by the server, and transmitting information about the calculated batch size to the client. The method may further include generating batch data of a size reflecting the transmitted information by generating a queue of a plurality of input data at the client, transmitting the generated batch data to the server, and performing an analysis based on the model on the batch data received from the server.

Abstract: There are provided a scenario similarity retrieval-based automatic scenario generation system and method. According to an embodiment, a scenario retrieval-based automatic scenario generation method includes: retrieving scenarios similar to a query scenario from a scenario DB for an autonomous driving test; filtering only scenarios that meet a selection condition from the retrieved scenarios; and converting components of the filtered scenarios to suit a target condition. Accordingly, a desired scenario may be automatically generated by retrieving a scenario similar to a targeted scenario, converting the retrieved scenario, and concretizing the scenario.

Abstract: A device and method for performing fast grid-based refining segmentation (FGRS) for video-based point cloud compression (V-PCC) is proposed. The method may include dividing a space of a three-dimensional (3D) point cloud into multiple grids to derive multiple voxels, searching for filled voxels including one or more points, searching for surrounding voxels which are filled voxels within a certain radius from each of the filled voxels, and searching for edge voxels which are present at a segment edge among all the filled voxels. The method may also include calculating smooth scores for surrounding voxels of each edge voxel and calculating a smooth score sum which is a smooth score for the edge voxel on the basis of the smooth scores of the surrounding voxels of the edge voxel, and updating a projection plane index (PPI) for each individual point in the edge voxel using the calculated smooth score sum.
