jax.random.exponential#
- jax.random.exponential(key, shape=(), dtype=<class 'float'>)[source]#
Sample Exponential random values with given shape and float dtype.
The values are distributed according to the probability density function:
\[f(x) = e^{-x}\]on the domain \(0 \le x < \infty\).
- Parameters:
key (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 (str | type[Any] | dtype | SupportsDType) – optional, a float dtype for the returned values (default float64 if jax_enable_x64 is true, otherwise float32).
- Returns:
A random array with the specified shape and dtype.
- Return type:
