Hyperbolic tangent activation function.
Computes the element-wise function:
\[\mathrm{tanh}(x) = \frac{e^x - e^{-x}}{e^x + e^{-x}}\]
- Parameters:
x (Array | ndarray | bool | number | bool | int | float | complex | Quantity) – Input array.
- Returns:
An array with the same shape as the input.
- Return type:
Array | Quantity
