Type VectorDeterministic

Namespace tensorflow.contrib.distributions

Parent _BaseDeterministic

Interfaces IVectorDeterministic

Vector `Deterministic` distribution on `R^k`.

The `VectorDeterministic` distribution is parameterized by a [batch] point `loc in R^k`. The distribution is supported at this point only, and corresponds to a random variable that is constant, equal to `loc`.

See [Degenerate rv](https://en.wikipedia.org/wiki/Degenerate_distribution).

#### Mathematical Details

The probability mass function (pmf) is

```none pmf(x; loc) = 1, if All[Abs(x - loc) <= atol + rtol * Abs(loc)], = 0, otherwise. ```

#### Examples
Show Example 
import tensorflow_probability as tfp
            tfd = tfp.distributions 
 # Initialize a single VectorDeterministic supported at [0., 2.] in R^2.
constant = tfd.Deterministic([0., 2.])
constant.prob([0., 2.])
==> 1.
constant.prob([0., 3.])
==> 0. 
 # Initialize a [3] batch of constants on R^2.
loc = [[0., 1.], [2., 3.], [4., 5.]]
constant = tfd.VectorDeterministic(loc)
constant.prob([[0., 1.], [1.9, 3.], [3.99, 5.]])
==> [1., 0., 0.]
