WebOct 15, 2024 · 3.3 Sinkhorn Algorithms with the Nyström Method. Although the Sinkhorn–Knopp algorithm has already yielded impressive algorithmic benefits, its computational complexity and memory usage are of the order of n 2, since such an algorithm involves the calculation of the n × n matrix e −ηC. Such a quadratic … WebSinkhorn-Knopp’s matrix balancing algorithm (Sinkhorn,1964; Sinkhorn and Knopp,1967). This approach was pushed forward for ML applications by Cuturi (2013). Sinkhorn distances are smooth and amenable to GPU computations, which make them suitable as a loss function in model training (Frogner et al.,2015; Mensch et al.,2024).
