Tanh#

class brainstate.nn.Tanh(name=None)#

Applies the Hyperbolic Tangent (Tanh) function element-wise.

Tanh is defined as:

\[\text{Tanh}(x) = \tanh(x) = \frac{\exp(x) - \exp(-x)} {\exp(x) + \exp(-x)}\]

Shape#

  • Input: \((*)\), where \(*\) means any number of dimensions.

  • Output: \((*)\), same shape as the input.

Examples

>>> import brainstate.nn as nn
>>> import brainstate
>>> m = nn.Tanh()
>>> x = brainstate.random.randn(2)
>>> output = m(x)
