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

Sample from a Rademacher distribution.

The values are distributed according to the probability mass function:

\[f(k) = \frac{1}{2}(\delta(k - 1) + \delta(k + 1))\]

on the domain \(k \in \{-1, 1}\), where delta(x) is the dirac delta function.

Parameters:
Return type:

Array

Returns:

A jnp.array of samples, of shape shape. Each element in the output has a 50% change of being 1 or -1.
