OUActionNoise	Calculates Ornstein-Uhlenbeck process noise.

class exarl.utils.OUActionNoise.OUActionNoise2(mean=0, start_std=0.15, stop_std=0.05, damping=0.005)

Calculates Ornstein-Uhlenbeck process noise.

Variables

• mean (float) –

• start_std (float) – standard deviation default value

• stop_std (float) – standard deviation limit

• damping (float) – rate at which the noise trajectory is damped towards the mean

Parameters

• mean (float, optional) – by default 0

• start_std (float, optional) – standard deviation default value, by default 0.15

• stop_std (float, optional) – standard deviation limit, by default 0.05

• damping (float, optional) – by default 0.005

__call__(self)

Generate noise

Returns

float – noise

reset(self)

Reset noise generator to start_std
