tf.math.xlog1py
Compute x * log1p(y).
tf.math.xlog1py(
x, y, name=None
)
Given x and y, compute x * log1p(y). This function safely returns zero when x = 0, no matter what the value of y is.
Example:
tf.math.xlog1py(0., 1.)
<tf.Tensor: shape=(), dtype=float32, numpy=0.>
tf.math.xlog1py(1., 1.)
<tf.Tensor: shape=(), dtype=float32, numpy=0.6931472>
tf.math.xlog1py(2., 2.)
<tf.Tensor: shape=(), dtype=float32, numpy=2.1972246>
tf.math.xlog1py(0., -1.)
<tf.Tensor: shape=(), dtype=float32, numpy=0.>
