About Advanced AI and Deep Reinforcement Learning

Reinforcement learning (RL) is an area of machine learning and considered as advanced AI. Moreover, concerned with how software agents ought to take actions in an environment in order to maximize the notion of cumulative reward. Reinforcement learning is one of three basic machine learning paradigms, alongside supervised learning and unsupervised learning.

Reinforcement Learning in Python.

Reinforcement learning differs from supervised learning in not needing labeled input/output pairs to be presented, and in not needing sub-optimal actions to be explicitly corrected. Instead, the focus is on finding a balance between exploration of uncharted territory and exploitation of current knowledge.

About  this Course

This course is all about the application of deep learning and neural networks to reinforcement learning. Specifically, the combination of deep learning with reinforcement learning has led to AlphaGo beating a world champion in the strategy game Go, it has led to self-driving cars, and it has led to machines that can play video games at a superhuman level.

The world is changing at a very fast pace. The state of California is changing its regulations so that self-driving car companies can test their cars without a human in the car to supervise. Reinforcement learning is an entirely different kind of machine learning than supervised and unsupervised learning.

Supervised and unsupervised machine learning algorithms are for analyzing and making predictions about data, whereas reinforcement learning is about training an agent to interact with an environment and maximize its reward. Unlike supervised and unsupervised learning algorithms, reinforcement learning agents have an impetus they want to reach a goal.

This is such a fascinating perspective, it can even make supervised / unsupervised machine learning, and “data science” seems boring in hindsight. Why train a neural network to learn about the data in a database, when you can train a neural network to interact with the real-world?

While deep reinforcement learning and AI has a lot of potentials, it also carries with it a huge risk. Bill Gates and Elon Musk have made public statements about some of the risks that AI poses to economic stability and even our existence. Also don’t think like humans, and so they come up with novel and non-intuitive solutions to reach their goals, often in ways that surprise domain experts – humans who are the best at what they do.

Open AI is a non-profit founded by Elon Musk, Sam Altman (Y Combinator), and others, in order to ensure that AI progresses in a way that is beneficial, rather than harmful. Part of the motivation behind Open AI is the existential risk that AI poses to humans. They believe that open collaboration is one of the keys to mitigating that risk.

One of the great things about Open AI is that they have a platform called the Open AI Gym, which will make heavy use of this course. It allows anyone, anywhere in the world, to train their reinforcement learning agents in standard environments. In this course, you will build upon what you did in the last course by working with more complex environments, specifically, those provided by the Open AI Gym:

  • CartPole
  • Mountain Car
  • Atari games

To train effective learning agents, you will need new techniques of advanced AI. You will also extend your knowledge of temporal difference learning by looking at the TD Lambda algorithm, look at a special type of neural network called the RBF network, look at the policy gradient method, and you will end the course by looking at Deep Q-Learning (DQN) and A3C (Asynchronous Advantage Actor-Critic).
