Abstract: An apparatus for predicting performance of a wheel in a vehicle: includes a learning device that generates a latent space for a plurality of two-dimensional (2D) wheel images based on a convolutional autoencoder (CAE), extracts a predetermined number of the plurality of 2D wheel images from the latent space, and learns a dataset having the plurality of 2D wheel images and performance values corresponding to the plurality of 2D wheel images; and a controller that predicts performance for the plurality of 2D wheel images based on a performance prediction model obtained by the learning device.

Abstract: Disclosed herein are a system for content recommendation service, a content recommendation device and a method of operating the same. The system can recommend personalized content directly related with a recommendation target, irrespectively of whether the content consumption history of the recommendation target user is sufficient to analyze the purchase/use pattern or whether there are other users having similar purchase/user pattern with the recommendation target user. As a result, the recommendation reliability can be improved.

Abstract: A hermetic compressor capable of insulating connectors (43), to which a plurality of lead lines (42) connected to a terminal block (41) and a plurality of stator coils (31a) used in a stator (31) are connected, without using a separate insulator, and capable of preventing defective insulation of the connectors due to vibration or friction during operation of the compressor. The hermetic compressor comprises a compression device (20) to compress a refrigerant, the stator constituting a drive device (30) to drive the compression device, the plurality of lead lines to apply electric power to the stator, the plurality of stator coils used in the stator, the plurality of connectors, one of the lead lines and one of the stator coils being connected to each connector, and an insulation member (50) having a plurality of seating recesses (52), in which the connectors are seated, respectively, and a plurality of fixing grooves (55), in which the lead lines are fixed, respectively.
