tf.math.log_sigmoid

View source on GitHub

Computes log sigmoid of x element-wise.

tf.math.log_sigmoid(
    x, name=None
)

Specifically, y = log(1 / (1 + exp(-x))). For numerical stability, we use y = -tf.nn.softplus(-x).

Args
x A Tensor with type float32 or float64.
name A name for the operation (optional).
Returns
A Tensor with the same type as x.
