Deep Reinforcement Learning

Nanodegree Program

The Deep Reinforcement Learning Nanodegree has four courses: Introduction to Deep Reinforcement Learning, Value-Based Methods, Policy-Based Methods, and Multi-Agent RL. Students learn to implement classical solution methods, define Markov decision processes, policies, and value functions, and derive Bellman equations. They learn dynamic programming, Monte Carlo methods, temporal-difference methods, deep RL, and apply these techniques to solve real-world problems. They learn to train agents to navigate virtual worlds, generate optimal financial trading strategies, and apply RL to multiple interacting agents.

Course 1 1 day

Introduction to Deep Reinforcement Learning

Lesson 1

Welcome to Deep Reinforcement Learning

Welcome to the Deep Reinforcement Learning Nanodegree program!

Lesson 2

Getting Help

You are starting a challenging but rewarding journey! Take 5 minutes to read how to get help with projects and content.

Lesson 3

Get Help with Your Account

What to do if you have questions about your account or general questions about the program.

Lesson 4

Learning Plan

Obtain helpful resources to accelerate your learning in this first part of the Nanodegree program.

Lesson 5

Introduction to RL

Reinforcement learning is a type of machine learning where the machine or software agent learns how to maximize its performance at a task.

Lesson 6

The RL Framework: The Problem

Learn how to mathematically formulate tasks as Markov Decision Processes.

Lesson 7

The RL Framework: The Solution

In reinforcement learning, agents learn to prioritize different decisions based on the rewards and punishments associated with different outcomes.

Lesson 8

Monte Carlo Methods

Write your own implementation of Monte Carlo control to teach an agent to play Blackjack!

Lesson 9

Temporal-Difference Methods

Learn about how to apply temporal-difference methods such as SARSA, Q-Learning, and Expected SARSA to solve both episodic and continuing tasks.

Lesson 10

Solve OpenAI Gym's Taxi-v2 Task

With reinforcement learning now in your toolbox, you're ready to explore a mini project using OpenAI Gym!

Lesson 11

RL in Continuous Spaces

Learn how to adapt traditional algorithms to work with continuous spaces.

Lesson 12

What's Next?

In the next parts of the Nanodegree program, you'll learn all about how to use neural networks as powerful function approximators in reinforcement learning.

Course 2 4 weeks

Value-Based Methods

Apply deep learning architectures to reinforcement learning tasks. Train your own agent that navigates a virtual world from sensory data.

Lesson 1

Study Plan

This lesson covers the study plan and prerequisites for this course.

Lesson 2

Deep Q-Networks

Extend value-based reinforcement learning methods to complex problems using deep neural networks.

Lesson 3 • Project

Project: Navigation

Train an agent to navigate a large world and collect yellow bananas, while avoiding blue bananas.

Course 3 4 weeks

Policy-Based Methods

Lesson 1

Study Plan

Obtain helpful resources to accelerate your learning in the third part of the Nanodegree program.

Lesson 2

Introduction to Policy-Based Methods

Policy-based methods try to directly optimize for the optimal policy.

Lesson 3

Policy Gradient Methods

Policy gradient methods search for the optimal policy through gradient ascent.

Even though the content is great, I enrolled in this program 5 years ago and it was the same content. They should’ve updated it and made the videos and lessons better.

It covers the topic in sufficient detail and is not just a cursory introduction. Coding exercises and projects are pretty intensive.
