In virtue of fast Fourier trans- form, the computational cost of CBE is only O(dlogd), much less than O(d2) of … WebDec 7, 2024 · The kernel embedding algorithm is an important component for adapting kernel methods to large datasets. Since the algorithm consumes a major computation cost in the testing phase, we propose a novel teacher-learner framework of learning computation-efficient kernel embeddings from specific data.
WebJan 1, 2015 · The second method, Circulant Binary Embedding (CBE), generates binary codes by projecting the data with a circulant matrix . The circulant structure enables the use of Fast Fourier Transformation to speed up the computation. This further improves the time complexity to \mathcal {O} (d\log {d}).
