WebMar 5, 2024 · When hashing a piece of data, the hash function should be able to take an arbitrary length of data and map it to a fixed-length index that is unique to the value. In … WebAbstract. We propose a consolidated cross-validation (CV) algorithm for training and tuning the support vector machines (SVM) on reproducing kernel Hilbert spaces. Our consolidated CV algorithm utilizes a recently proposed exact leave-one-out formula for the SVM and accelerates the SVM computation via a data reduction strategy.
