是使用最广的激活函数,同时也有许多变体(leaky ReLU,PReLU,EIU和SeLU)。ReLU计算简单,而且能够解决梯度消失问题,但同样面临两个主要问题:1)它的范围是从零到无限,这意味着它可以炸裂激活(blow up the activation);2)负半轴导致的稀疏性。尽管如此,ReLU兼顾了简易性和高效性,通常可做为默认的激活函数。如果发生了...
Using Hyperparameter Optimization (HPO) | CS Series Urika-CS AI and Analytics Applications Guide 14UP00 (S-3024)
This nontrivial class of bilevel programs provides a powerful modelling framework for dealing with applications arising from hyperparameter selection in machine learning. Thanks to the full convexity of the lower level program, the value function of the lower level program turns out to be convex ...
