Shifting Mean Activation Towards Zero with Bipolar Activation Functions

WebIn general, for any ReLU-family activation function f, we can deﬁne its bipolar version as follows: f B(x i) = ˆ f(x i); if imod 2 = 0 f( x i); if imod 2 6= 0 (2) For convolutional layers, … WebWe explore the training of deep vanilla recurrent neural networks (RNNs) with up to 144 layers, and show that bipolar activation functions help learning in this setting. On the Penn Treebank and Text8 language modeling tasks we obtain competitive results, improving on the best reported results for non-gated networks. WebThe sigmoid function is also called a squashing function as its domain is the set of all real numbers, and its range is (0, 1). Hence, if the input to the function is either a very large negative number or a very large positive number, the output is always between 0 and 1. Same goes for any number between -∞ and +∞. porky death
