Soft threshold

WebJul 16, 2024 · For real-valued data, the definition of the soft-thresholding operator is given in the famous paper of Friedmann, Hastie und Tibshirani, Regularization Paths for Generalized Linear Models via Coordinate Descent, as. S ( z, λ) = sign ( z) ( z − γ) + for z, γ ∈ R. From this, I think it is straightforward to extend it to the complex ... WebWe propose an alternative approach to spatial variable selection in scalar-on-image regression by modelling the regression coefficients through soft-thresholding of a latent Gaussian process. The soft-thresholding function is well known for its relation with the lasso estimate when the design matrix is orthonormal ( Tibshirani, 1996 ), and here ...
