Generates Tensor of positive reals drawn from a Rayleigh distributions.
tfp.random.rayleigh( shape, scale=None, dtype=tf.float32, seed=None, name=None ) The probability density function of a Rayleigh distribution with scale parameter is given by:
f(x) = x scale**-2 exp(-x**2 0.5 scale**-2) For more details, see Rayleigh distribution
Args | |
|---|---|
shape | Vector-shaped, int Tensor representing shape of output. |
scale | (Optional) Positive float Tensor representing Rayleigh scale. Default value: None (i.e., scale = 1.). |
dtype | (Optional) TF dtype representing dtype of output. Default value: tf.float32. |
seed | PRNG seed; see tfp.random.sanitize_seed for details. Default value: None (i.e., no seed). |
name | Python str name prefixed to Ops created by this function. Default value: None (i.e., 'random_rayleigh'). |
Returns | |
|---|---|
rayleigh | Tensor with specified shape and dtype consisting of positive real values drawn from a Rayleigh distribution with specified scale. |
