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.>
