WebOct 15, 2024 · Inspired by the greedy randomized Kaczmarz method, we propose a probability criterion which can capture subvectors of the residual whose norms are relatively large. According to this probability criterion we select a submatrix randomly from the coefficient matrix, then average the projections of the current iteration vector onto each … WebMar 10, 2015 · The relation between maximizing variance and the eigen-decomposition of the covariance matrix is as follows. Assume that D is the data matrix after centering the columns. We need to find the direction of maximum variance. For any unit vector v, the variance after projecting along v is. E[(Dv)tDv] = vtE[DtD]v = vtCov(D)v.
WebDec 1, 2024 · Greedy projection algorithm is based on incremental surface growing principle and a greedy type approach (Bayazit, 2024). The core of this algorithm is to grow and extend the mesh from a new starting triangle until all the points in the cloud have been considered or no more valid triangles can be connected to the resultant mesh.
