WebThe svds algorithm produces a warning since the maximum number of iterations were performed but the tolerance could not be met. The most effective way to address convergence problems is to increase the maximum size of the Krylov subspace used in the calculation by using a larger value for 'SubspaceDimension'. WebJan 15, 2024 · Whether to use local search or not is controlled with the method sub-option "PostProcess". If we put "PostProcess" to False, then the max iterations specification is respected (and message of non-convergence might be given.) Here is a demonstration: WebIn rare cases, when some of the points (rows of ‘x’) are extremely close, the algorithm may not converge in the “Quick-Transfer” stage , signalling a warning (and returning ‘ifault = 4’). Slight rounding of the data may be advisable in that case. In these cases, you may need to switch to the Lloyd or MacQueen algorithms. on this day in history july 24
