WebApplication of deep neural networks (DNN) in edge computing has emerged as a consequence of the need of real time and distributed response of different devices in a large number of scenarios. To this end, shredding these original structures is urgent due to the high number of parameters needed to represent them. As a consequence, the most … WebIt controls relative importance of sparsity term. Lambda and Beta specify the relative importance of their terms in cost function. Epsilon (if they've used the same notation with Andrew Ng) is regularization parameter for whitening process which has low-pass filter effect on input. That has some important effects on reconstruction methods. secure access service edge sase solutions
