LSSVM model used to estimate the lower and upper bounds of the PIs in the LUBE method. (K)1 and (b)1 represent the kernel function and bias of the first LSSVM model, respectively; (K)2 and (b)1 represent the kernel function and bias of the second LSSVM model, respectively; the outputs (y)1 and (y)1 generated by the two LSSVM models correspond to upper and lower bounds of future unknown displacement, respectively.
