# MATLAB: Noise parameters in Reinforcement learning DDPG

What should be the values of Noise parameters (for agent) if my action range is between -0.5 to -5 in DDPG reinforcement learning I want to explore whole action range for each sample time? Also is there anyway to make the noise options (for agent) independent of sample time?

halflife = log(0.5)/log(1-VarianceDecayRate)
