WebMar 18, 2024 · 5. The soft-thresholding function finds the minimizer of an objective function that involves data fitting in an ℓ 2 sense as well as minimization of the ℓ 1 norm (i.e. absolute value). The Lecture Notes - Penalty and Shrinkage Functions for Sparse Signal Processing gives a good discussion of how the soft threshold function is derived. WebJun 8, 2024 · A rigrsure adaptive soft threshold noise reduction based on discrete wavelet transform (RA-DWT) algorithm is proposed to separate and reconstruct the respiratory and heartbeat signals. The algorithm is proved by measured data that it can effectively suppress harmonic and noise interference, and greatly improve the accuracy of respiration and …
