WebAn iterative solving method is proposed; at each iteration convex matrix subproblem is formulated and solved using standard Convex Optimization algorithms. Global convergence of the method is proven. Web2 Jan 2024 · In this paper, we have proposed a nove12-stage method, namely, CT-NNBI of imputing incomplete gene expression matrices using Discrete Cosine Transform Domain Sparsity and Nuclear Norm Constraint with Split Bregman Iteration (CT-NNBI) that yields smaller imputation errors, consistently, at all levels of observability.

Despite its simplicity, Split LBI outperforms the popular generalized Lasso in both theory and experiments. A theory of path consistency is presented that equipped with a proper early stopping, Split LBI may achieve model selection
