Abstract: An automation method of an artificial intelligence (AI)-based diagnostic technology for equipment application includes receiving one or more pieces of data among vibration data, noise data, and controller area network (CAN) data, a data input processing operation of trimming the input data, an operation of extracting features from the trimmed data, setting a setting value of a hyper-parameter with respect to the one or more pieces of data thereamong, and generating a total of N models to include both of machine learning (ML) and deep learning (DL) as N individual models and generating ensemble prediction model structures for the N individual models. As a parameter updating is being proceeded due to the hyper-parameter so as to minimize values of cost functions of the N individual models, a reward for model accuracy performance is optimized and the ensemble prediction model structures of the N individual models change.

Abstract: A method for fabricating a display window member for a portable terminal includes: fabricating a surface sheet to be attached to a surface of the window member; introducing the surface sheet into a mold; and molding the body of the window member by pouring poly synthetic resin into the mold, and at the same time, attaching the surface sheet to the outer surface of the body. Since the window member fabrication method employs a dual injection molding using polymer synthetic resin, the fabrication method can easily reduce the weight of the window member compared to the conventional fabrication method using a glass material only and can reinforce the surface hardness of the window member while easily fabricating the window member.
