This means that LASSO can automatically select the most important independent variables by shrinking the less important predictors to 0.The proposed SCCA method has a strong upper bound of grouping effects for both positively and negatively highly correlated variables. We show that, on both synthetic and real neuroimaging genetics data, the proposed SCCA method performs better than or equally to the conventional methods using fused lasso or graph/network guided fused …

Jul 1, 2021 · Data envelopment analysis (DEA) is a popular and effective tool to measure the relative efficiency of decision making units (DMUs) with multiple inputs and multiple outputs [10]. 1 DEA has been widely used to analyze many industries. 2 It has also been used as a data-driven tool for building a composite index and for balanced benchmarking [46]. Lasso regression methods are widely used in domains with massive datasets. Lasso expects many coefficients to be zero and expects only a small subset to be nonzero. Ridge regression performs well with many predictors, each of which has a small effect (Ogutu et al., 2012). Ridge regression shrinks the coefficients and does not force coefficients ...Jan 1, 2017 · We treat the estimation of a sparse set of sources emitting plane waves observed by a sensor array as a complex-valued LASSO (c–LASSO) problem where the usual ℓ 1-norm constraint is replaced by the ℓ 1-norm of a matrix D times the solution vector.
