Abstract: Disclosed herein are a reward apparatus and method for blockchain-based blockchain-based Reconfigurable Intelligent Surface (RIS) infrastructure sharing. The reward apparatus for blockchain-based RIS infrastructure sharing may provide a service to a service user terminal through an RIS node, verify a contribution of the RIS node to provision of the service quantified by the RIS node using a first blockchain network, and provide a reward to the RIS node depending on the contribution.

Abstract: Disclosed herein are an apparatus and method for generating a data set. The apparatus includes one or more processors and executable memory for storing at least one program executed by the one or more processors. The at least one program classifies collected data into numerical feature data and categorical feature data using a filter method, performs correlation analysis on the numerical feature data and the categorical feature data using an analysis of variance (ANOVA) method and a Chi-Squared method, and generates a data set for supervised learning and a data set for unsupervised learning using correlation scores calculated through correlation analysis.
