jax.random.normal#
- jax.random.normal(key, shape=(), dtype=<class 'float'>)[source]#
Sample standard normal random values with given shape and float dtype.
The values are returned according to the probability density function:
\[f(x) = \frac{1}{\sqrt{2\pi}}e^{-x^2/2}\]on the domain \(-\infty < x < \infty\)
- Parameters:
key (
Union[Array,ndarray,bool_,number,bool,int,float,complex]) – a PRNG key used as the random key.shape (
Union[Sequence[int],NamedShape]) – 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:
- Returns:
A random array with the specified shape and dtype.
