RL -- Deep Reinforcement Learning (Learn effectively like a human)

With the brute force of GPUs and the better understanding of AI, we beat the GO champions and Face ID comes with every new iPhone. But in the robotic world, training a robot to peel lettuce makes the news. Even with an unfair advantage over computation speed, a computer still cannot manage tasks that we take it for granted. The dilemma is AI does not learn as effectively as the human. We may be just a couple of papers away from another breakthrough or we need to learn more effectively.
