Helicopters have highly stochastic, nonlinear, dynamics, and autonomous Reinforcement learning and dynamic programming have been utilized extensively in solving the problems of ATC. One such issue with Markov decision processes (MDPs) and partially observable Markov decision processes (POMDPs) is the size of the state space used for collision avoidance.

B. Q-learning The goal in reinforcement learning is always to maxi-mize the expected value of the total payoff (or expected return). In Q-learning, which is off-policy, we use the Bellman equation as an iterative update Q i+1(s;a) = E s0˘"[r+ max a0 Q i(s 0;a)js;a] (3) where s0is the next state, ris the reward, "is the envi-ronment, and QCreate a boolean to detect terminal states: terminal = False.

To meet the demands of such applications that require quickly learning or adapting to new tasks, this thesis focuses on meta-reinforcement learning (meta-RL). Specifically we consider a setting where the agent is repeatedly presented with new tasks, all drawn from some related task family. The agent must learn each new task in only a few shots ...

Function approximators like deep neural networks help scaling reinforcement learning to complex problems. Deep RL is hard, but has demonstrated impressive results in the past few years. In the other hand, it still needs to be re ned to be able to beat humans at some tasks, even "simple" ones.Ng's research is in the areas of machine learning and artificial intelligence.
