tanh#

Signature#

nabla.tanh(arg: 'Array') -> 'Array'

Description#

Computes the element-wise hyperbolic tangent of an array.

The tanh function is a common activation function in neural networks, squashing values to the range [-1, 1].

Parameters#

  • arg (Array): The input array.

Returns#

  • Array: An array containing the hyperbolic tangent of each element.

Examples#

>>> import nabla as nb
>>> x = nb.array([-1.0, 0.0, 1.0, 20.0])
>>> nb.tanh(x)
Array([-0.7615942,  0.       ,  0.7615942,  1.       ], dtype=float32)
