    CPC classification number: G06N5/022

    Abstract: Provided are a preprocessing device and method for learning data of a classifier for improving stability and robustness of learning and prediction of a classifier in a varying feature space. The preprocessing device for learning data of a classifier according to the present invention includes a variable spatial information extractor configured to receive data for learning of the classifier, calculate an appearance frequency of each variable combination based on the data, and calculate a cumulative appearance frequency of each variable combination by cumulating and summing the appearance frequency of each variable combination, and a data preprocessor configured to generate a prediction variable—target variable frequency matrix based on the appearance frequencies of each variable combination, apply Laplace smoothing to the frequency matrix according to the cumulative appearance frequency to calculate a probability value of each variable combination, and provide the probability value of each variable combination to the classifier.

    Abstract: A method for reporting sidelink HARQ response information, performed by a terminal, includes the steps of: receiving, from a base station, information on allocation of a PSSCH resource for PSSCH transmission; determining a PSFCH resource for PSFCH reception corresponding to the PSSCH transmission; determining a transmission time point of HARQ response information corresponding to the PSSCH transmission; and transmitting the HARQ response information, corresponding to the PSSCH transmission, to the base station at the determined time point, wherein the transmission time point of the HARQ response information is expressed as a time offset, L, from a time point of the PSFCH resource, and information on the transmission time point of the HARQ response information is transmitted from the base station to the terminal.
