摘要
The present invention discloses an on-line verification apparatus and method for verifying a time-varying signal through a kernel regression model. According to an embodiment of the present invention, an online verification apparatus includes a data conversion unit for converting memory data using a time-dependent conversion formula based on a difference between a first time and a second time, A distance calculator for calculating a Euclidean distance with respect to the query vector using the converted memory data, a Gaussian kernel function applied to the calculated Euclidean distance to calculate a kernel weight And a response variable calculator for calculating a response variable for the query vector using the calculated weight value.
