Table 3 List of activation functions used in the AE layers
From: Autoencoder-bank based design for adaptive channel-blind robust transmission
Activation functions | ||||
|---|---|---|---|---|
Name | Function | Output range | ||
Linear | \(s_m\) | \((-\infty ,+\infty )\) | ||
Relu | \({\max }(0,s_m)\) | \([0,+\infty )\) | ||
Softmax | \(\frac{e^{s_m}}{\sum _m{s_m}}\) | (0, 1) | ||
Sigmoid | \(\frac{1}{1+e^{-s_m}}\) | (0, 1) | ||
tanh | \(\tanh (s_m)\) | \((-1,1)\) | ||
