Abstract: In a method of responding based on sentence paraphrase recognition for dialog system, main keywords of a domain and patterns thereof are recognized and extracted based on a morpheme analysis result in a pre-processing process. Question domains/sub-categories/dialogue-acts are classified using the morpheme analysis result and the extracted main keywords and patterns. Learning a model is performed using classification features of the classified question domains, sub-categories, and dialogue-acts as semantic features of query sentences, and sentence semantic vectors are extracted by measuring similarity between the vectors. A language model of letters is trained and similarity in expression and structure is analyzed by extracting a sentence expression vector based on the letter. An answer to a similar question is provided by generating a vector containing semantic and expressive information about an input query sentence based on analyzed semantic and expressive similarities, and finding a similar query sentence from FAQ knowledge using a paraphrase recognition technology. In a dialog system for automatic Q&A service such as a chatbot for customer consultation, it is possible to provide related answers by exploring question-and-answer knowledge (questions) that have similar meanings and intentions of input sentences (query) through paraphrase recognition technology.

Abstract: Disclosed is a ray clustering learning method based on weakly-supervised learning for denoising using ray tracing. The ray clustering learning method is for learning a denoising model for removing noise from a rendered image through ray tracing, and includes extracting a feature of a simulated ray through the ray tracing and clustering the ray through contrastive learning for the feature.

Abstract: The disclosed technology generally relates to a tire and more particularly to a non-pneumatic tire. The non-pneumatic tire that has maneuverability similar to a pneumatic tire even without using air pressure, and can support the load of a vehicle and can guide performance-oriented tire deformation behavior by using a meta structure. In an aspect, a non-pneumatic tire includes a tread that comes in contact with the ground, a rim that is connected with an axle, and a spoke unit that serves as a structural support between the rim and the tread, in which the spoke unit is formed in a meta structure in which unit structures are repeated.
