tf_agents.utils.common.OUProcess

A zero-mean Ornstein-Uhlenbeck process.

tf_agents.utils.common.OUProcess(
    initial_value,
    damping=0.15,
    stddev=0.2,
    seed=None,
    scope='ornstein_uhlenbeck_noise'
)

initial_value Initial value of the process.
damping The rate at which the noise trajectory is damped towards the mean. We must have 0 <= damping <= 1, where a value of 0 gives an undamped random walk and a value of 1 gives uncorrelated Gaussian noise. Hence in most applications a small non-zero value is appropriate.
stddev Standard deviation of the Gaussian component.
seed Seed for random number generation.
scope Scope of the variables.
