Softplus activation function.
tf.keras.ops.softplus(
x
)
It is defined as f(x) = log(exp(x) + 1), where log is the natural logarithm and exp is the exponential function.
| Args | |
|---|---|
x | Input tensor. |
| Returns | |
|---|---|
A tensor with the same shape as x. |
Example:
x = keras.ops.convert_to_tensor([-0.555, 0.0, 0.555]) keras.ops.softplus(x) array([0.45366603, 0.6931472, 1.008666], dtype=float32)
