jax.random.laplace#

jax.random.laplace(key, shape=(), dtype=<class 'float'>)[source]#

Sample Laplace random values with given shape and float dtype.

The values are distributed according to the probability density function:

\[f(x) = \frac{1}{2}e^{-|x|}\]
Parameters:

  • key (Union[Array, ndarray, bool_, number, bool, int, float, complex]) – a PRNG key used as the random key.

  • shape (Sequence[int]) – optional, a tuple of nonnegative integers representing the result shape. Default ().

  • dtype (Union[str, type[Any], dtype, SupportsDType]) – optional, a float dtype for the returned values (default float64 if jax_enable_x64 is true, otherwise float32).

Return type:

Array

Returns:

A random array with the specified shape and dtype.
