	Soft Shrink operator is defined as, $\begin{eqnarray} f(x) &=& \begin{cases} x - \lambda & : x > \lambda \\ x + \lambda & : x < -\lambda \\ 0 & : otherwise. \\ \end{cases} \\ f'(x) &=& \begin{cases} 1 & : x > \lambda \\ 1 & : x < -\lambda \\ 0 & : otherwise. \end{cases} \end{eqnarray}$ . More...

Detailed Description

Author: Lakshya Ojha

The soft shrink function has threshold proportional to the noise level given by the user. The use of a Soft Shrink activation function provides adaptive denoising at various noise levels using a single CNN (Convolution Neural Network) without a requirement to train a unique CNN for each noise level.
