Global convergence of the reduced half thresholding algorithm is proven, and two techniques: the Newton acceleration technique and the shrinking technique are presented to improve the performance. Compared with the state-of-the-art algorithms, the numerical results show that the presented algorithms are...

Our second contribution is a matrix-free algorithm to find a minimizer of the regularized reaper which is also suited for high-dimensional data. The algorithm couples a primal-dual minimization approach with a thick-restarted Lanczos process. This appears to be the first efficient convex variational...
it can be applied to image recognition and speech recognition as well. The major innovation is the integration of soft thresholding as nonlinear transformation layers into ResNets. Moreover, the thresholds are automatically determined by a specially designed sub-network, so that no professional experti...
To compute the corresponding regularized solutions, we analyze an iterative algorithm that amounts to a Landweber iteration with thresholding (or nonlinear shrinkage) applied at each iteration step. We prove that this algorithm converges in norm. © 2004 Wiley Periodicals, Inc. 展开 ...

To enable the algorithm to correctly detect the particle surface, two masks are created, via interactive thresholding and smoothing if necessary. The first contains all active materials (Fig. 2b), and the second contains any pores/internal voids within the data set (Fig. 2c). These masks are...
We also show that this algorithm can be used to build a remarkably simple machine-learning model capable of outperforming deep-learning models in detecting Parkinson’s disease from a single digital handwriting test.Similar content being viewed by others Reconstructing computational system dynamics from ...
