Are you looking for Udacity Deep Reinforcement Learning Review?… If yes, first, read my latest Udacity Deep Reinforcement Learning Nanodegree Review and then decide whether to enroll or not in the program.

Now, without any further ado, let’s get started-

Udacity Deep Reinforcement Learning Review

Before starting the Udacity Deep Reinforcement Learning Review, I would like to mention one important thing regarding Udacity Deep Reinforcement Learning Nanodegree.

Udacity Deep Reinforcement Learning Nanodegree is not for beginners. Yes, If you are a beginner with no previous knowledge of Python, Statistics, Machine Learning, and Its Frameworks(TensorFlow or Keras), I would not recommend you to enroll in this Nanodegree Program.

Udacity Deep Reinforcement Learning Nanodegree is an advanced-level program and only suitable for those who have previously worked on Machine Learning and Deep Learning problems and know any Deep Learning framework such as TensorFlow, Keras, or PyTorch.

My domain is “Depression Detection using Social Media Images” and for this task, I have collected the images from social media. For the Data Processing task, I thought to use Reinforcement Learning.

And then I heard about Udacity Deep Reinforcement Learning Nanodegree.

Reinforcement Learning is getting more popular day by day and it can perform better in a complex environment.

What is Reinforcement Learning?

Reinforcement Learning is also a machine learning problem. It is based on a self-learning mechanism.

Unlike in supervised learning, where the training dataset is present. But in Reinforcement Learning there is no supervision.

Reinforcement Learning is a hit-and-trial kind of learning. The main objective of a learner is to get maximum rewards.

The learner interacts dynamically with their environment. And the learner moves from one state to another. These rewards are given based on the action taken by the learner.

The guideline for which action to take in each state is called a policy.

Therefore, the objective of Reinforcement Learning is to find an optimal policy, so that rewards are maximized.

So, this way learner learns by himself.

So, this is the basic working of Reinforcement Learning. Now, let’s see What I have learned in Udacity Deep Reinforcement Learning Nanodegree Program.

Content and Projects of Udacity Deep Reinforcement Learning Nanodegree

The best thing I found in the Udacity Deep Reinforcement Learning Nanodegree program was its projects and quizzes. The whole Nanodegree program was comprised of various quizzes and projects.

There were 3 projects in this Nanodegree Program and 4 courses. The first course didn’t have any project because it was just an introduction to Reinforcement Learning. But from the second course, there was one project which I had to complete.

I found their technical mentor support very helpful. Whenever I got stuck and had doubts, I asked the mentor and he guided me.

These were the 4 courses-

1. Foundations of Reinforcement Learning
2. Value-Based Methods
3. Policy-Based Methods
4. Multi-Agent Reinforcement Learning

Course 1- Foundations of Reinforcement Learning

In this course, the instructor taught the basics of Reinforcement Learning and how to work on Reinforcement Learning Problems.

This was an interesting course for me. Because I was learning various new things which I was not aware of before.

I also learned about the Monte Carlo Method of Deep Reinforcement Learning. In Monte Carlo Method, there is no Model and the agent learn from the sampled experience. This was fun learning.

The instructor also taught us how we can solve the OpenAI Gym’s Taxi – V2 Task and Q-Learning. The overall course was excellent and the instructors were very friendly.

This course didn’t have any projects. So, after learning these concepts, I moved to the next course.

Course 2- Value-Based Methods

This was a total practice-based course. In this course, I learned Value-Based Methods. This was a little confusing course for me. Because the instructor taught building the CNN model in PyTorch. And I am more comfortable with TensorFlow.

That’s why I paused this course and learned PyTorch basics from other sources and then resumed this course.

And then I learned Deep Q-Learning and Value-Based Methods for real-world robotics.

After completing this course, There was one project, which I had to complete.

Project 1- Navigation

This was the first project of this Nanodegree program and it was totally a fun project. This was a game project and the goal of this project was to train an agent. And the agent has to navigate in a virtual world. And he has to collect “Yellow Bananas” as much as he can. But he has to avoid blue bananas.

For this project, I had to configure a Python 3.6 or PyTorch 0.4.0 environment and then I installed the Unity environment. The configuration of the Unity ML-agent environment was already completed by Udacity.

Once I completed this project, the reviewer from Udacity reviewed the project and approved the project.

After the successful approval, I moved to the next course.

Course 3- Policy-Based Methods

This course was the perfect mixture of theory and practice. In this course, I learned Policy-Based Methods and understand various methods to improve the Policy Gradient Methods.

The Actro-Critic Methods were also explained by the instructor. Actro-Critic learning is a kind of temporal difference (TD) method where you learn a policy function and a value function at the same time.

These concepts froze my mind because digesting all these complex topics was not easy. But Udacity projects and quizzes helped me to clear the concepts.

At the end of this course, I learn financial trading strategies using Deep Reinforcement Learning.

For me, completing this course was the same as completing the milestone. After this course, there was one project.

Project 2- Continuous Control

This was the second project of this Nanodegree program. The goal of this project was to move double-jointed arms into target locations.

The agent received a reward of +0.1 when his hand took a step in the goal location. The Agent’s goal was to maintain his position at the target location.

The course was hard but this project was again a fun game. After completing this course, I moved to the next and last course of this Nanodegree Program.

Course 4- Multi-Agent Reinforcement Learning

In this last course, I learned about Multi-Agent Reinforcement Learning.

Multi-Agent Reinforcement Learning basically involves multiple agents and they interact in a common environment. This concept blew my mind. It was a really interesting concept.

These multiple agents observed each other and then try to collaborate, compete, or collectively learn to achieve a particular task.

This course also discussed one Case Study Alphazero. AlphaZero algorithm was developed by DeepMind in 2018.

This algorithm trains two players for zero-sum board games and they can play against themselves. I found this course the most engaging and interesting as compared to other courses in this Nanodegree Program.

After this course, there was the last project which I had to complete. The project was also based on Multi-Agent Reinforcement Learning.

Project 3- Collaboration and Competition

This was the last project. In this project, I had to train two Reinforcement learning agents to play Table Tennis.

There were two agents who hit the ball and if the ball touch the net, the agent received a reward of +0.1. And if the ball hit the ground by the agent, then he received a reward of -0.01.

This project was really amazing and fun. But before starting this project, I had to choose between Policy-based vs Value-based Methods.

But overall, I enjoyed this project. The mentor was very helpful. I asked him many times throughout this project and he helped me by providing guidance.
