Ddpg for highway lane following in matlab
WebDDPG agents use a parametrized deterministic policy over continuous action spaces, which is learned by a continuous deterministic actor. This actor takes the current observation as input and returns as output an action that is a deterministic function of the observation. WebA highway lane following system steers a vehicle to travel within a marked lane. It also maintains a set velocity or safe distance to a preceding vehicle in the same lane. The system typically includes vision processing, sensor fusion, decision logic, …

It is fairly common to have Variance*sqrt (SampleTime) somewhere between 1 and 10% of your action range for Ornstein Uhlenbeck (OU) action noise. So in your case, the variance can be set between 4.5*0.01/sqrt (SampleTime) and 4.5*0.10/sqrt (SampleTime). The other important factor is the VarianceDecayRate, which …
