Fixed point continuation
WebGeneralized projected gradient (GPG) algorithm for matrix completion [29] used a fixed-point iteration algorithm to solve proximal operators for a kind of non-convex surrogate functions. It also uses the continuation strategy to update the regularization parameter. As suggested in the paper, the initial value of λ in GPG is set ‖ Y ‖ ∞ ... WebFixed Point Continuation with Approximate SVD (FPCA) and Canonical Polyadic (CP) decomposition for incomplete tensors to solve the problem of missing data. We apply these methods to expressways and a large urban road network to assess their performancefor differentscenarios. Index Terms— Missing data in large networks, low …
