tf.keras.activations.tanh

Hyperbolic tangent activation function.

tf.keras.activations.tanh(
    x
)

Example:

a = tf.constant([-3.0, -1.0, 0.0, 1.0, 3.0], dtype = tf.float32)
b = tf.keras.activations.tanh(a)
b.numpy()
array([-0.9950547, -0.7615942,  0.,  0.7615942,  0.9950547], dtype=float32)

Args
`x`	Input tensor.

Returns
Tensor of same shape and dtype of input `x`, with tanh activation: `tanh(x) = sinh(x)/cosh(x) = ((exp(x) - exp(-x))/(exp(x) + exp(-x)))`.
