This course is all about the application of&nbsp;deep learning&nbsp;and&nbsp;neural networks&nbsp;to&nbsp;reinforcement learning.
If you&rsquo;ve taken my first reinforcement learning class, then you know that reinforcement learning is on the bleeding edge of what we can do with AI.
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.
Reinforcement learning has been around since the 70s but none of this has been possible until now.
The world is changing at a very fast pace. The state of California is changing their regulations so that self-driving car companies can test their cars without a human in the car to supervise.
We&rsquo;ve seen that reinforcement learning is an entirely different kind of machine learning than supervised and unsupervised learning.
Supervised and unsupervised&nbsp;machine learning&nbsp;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 /&nbsp;unsupervised machine&nbsp;learning and "data science"&nbsp;seem 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 potential, it also carries with it huge risk.
Bill Gates&nbsp;and&nbsp;Elon Musk&nbsp;have made public statements about some of the risks that AI poses to economic stability and even our existence.
As we learned in my first reinforcement learning course, one of the main principles of training reinforcement learning agents is that there are unintended consequences when training an AI.
AIs don&rsquo;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.
OpenAI&nbsp;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 OpenAI 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 OpenAI is that they have a platform called the&nbsp;OpenAI Gym, which we&rsquo;ll be making heavy use of in this course.
It allows anyone, anywhere in the world, to train their reinforcement learning agents in standard environments.
In this course, we&rsquo;ll build upon what we did in the last course by working with more complex environments, specifically, those provided by the OpenAI Gym:
<ul>
<li>
CartPole
</li>
<li>
Mountain Car
</li>
<li>
Atari games
</li>
</ul>
To train effective learning agents, we&rsquo;ll need new techniques.
We&rsquo;ll extend our knowledge of temporal difference learning by looking at the TD Lambda&nbsp;algorithm, we&rsquo;ll look at a special type of neural network called the RBF network, we&rsquo;ll look at the policy gradient method, and we&rsquo;ll end the course by looking at Deep Q-Learning (DQN) and A3C (Asynchronous Advantage Actor-Critic).
Thanks for reading, and I&rsquo;ll see you in class!
&nbsp;
"If you can't implement it, you don't understand it"
<ul>
<li>
Or as the great physicist Richard Feynman said: "What I cannot create, I do not understand".
</li>
<li>
My courses are the ONLY courses where you will learn how to implement machine learning algorithms from scratch
</li>
<li>
Other courses will teach you how to plug in your data into a library, but do you really need help with 3 lines of code?
</li>
<li>
After doing the same thing with 10 datasets, you realize you didn't learn 10 things. You learned 1 thing, and just repeated the same 3 lines of code 10 times...
</li>
</ul>
&nbsp;
Suggested Prerequisites:
<ul>
<li>
College-level math is helpful (calculus, probability)
</li>
<li>
Object-oriented programming
</li>
<li>
Python coding: if/else, loops, lists, dicts, sets
</li>
<li>
Numpy coding: matrix and vector operations
</li>
<li>
Linear regression
</li>
<li>
Gradient descent
</li>
<li>
Know how to build ANNs and CNNs in Theano or TensorFlow
</li>
<li>
Markov Decision Proccesses (MDPs)
</li>
<li>
Know how to implement Dynamic Programming, Monte Carlo, and Temporal Difference Learning to solve MDPs
</li>
</ul>
&nbsp;
WHAT&nbsp;ORDER&nbsp;SHOULD&nbsp;I&nbsp;TAKE&nbsp;YOUR&nbsp;COURSES&nbsp;IN?:
<ul>
<li>
Check out the lecture "Machine Learning and AI&nbsp;Prerequisite Roadmap" (available in the FAQ of any of my courses, including the free Numpy course)
</li>
</ul>
&nbsp;
UNIQUE&nbsp;FEATURES
<ul>
<li>
Every line of code explained in detail - email me any time if you disagree
</li>
<li>
No wasted time "typing" on the keyboard like other courses - let's be honest, nobody can really write code worth learning about in just 20 minutes from scratch
</li>
<li>
Not afraid of university-level math - get important details about algorithms that other courses leave out
</li>

Awesome course as your decision of case studies cover various challenges. One thing I saw during the course is that you essentially called out the services by taking a gander at the API and everything appeared to be basic and straightforward. However, I felt a few additional options could be examined as this would be challenging when we design or carve out services from the API definitions. Also, Database decisions like NoSQL, SQL, ... (absent a lot of discussion), are made. It would have been stunningly better assuming that it was explained why such decisions are made for each help.

This course is exactly what it says in the title and I preferred the utilization of examples to show what questions to ask while gathering requirements, and what sort of solutions the teacher could imagine to address them. The only area I could see for development is an explanation near the start of a portion of the design patterns utilized (CQRS especially, as it's alluded to multiple times in the course). However, a few patterns were explained in the latter talks.

<h2 id="user-content-getting-started">Getting started</h2>
4 methods to find PSSH:
<ol>
<li>
The simplest one: PSSH is clearly indicated in MPD file. Download MPD file (browser add-on "MPD Detector" will give you MPD link or filtering for <code>mpd</code> in the <code>network</code> tab of devoloper tools (ctrl + shift + c)), open it with Notepad, search for pssh value.
</li>
<li>
If there is KID, but no PSSH in MPD, calculate PSSH by using KID:
</li>
</ol>
Using <a title="this" href="https://tools.axinom.com/generators/PsshBox" rel="nofollow">this</a> website you can get the PSSH by entering in the <code>urn:uuid:</code> into the <code>System ID</code> field and entering the <code>cenc:default_KID=</code> into the <code>KEY IDs</code> field without the quotes <code>""</code>
Eample:
<a title="One" href="https://cdm-project.com/How-To/Obtaining-PSSH/media/branch/main/example_one.png?raw=true" target="_blank" rel="nofollow noopener"><img title="One" src="https://cdm-project.com/How-To/Obtaining-PSSH/media/branch/main/example_one.png?raw=true" alt="One:" /></a>
<h2 id="user-content-recommended-method"></h2>
<h2 id="user-content-recommended-method">Recommended method</h2>
<ol start="3">
<li><a title="EME Logger Script" href="https://greasyfork.org/en/scripts/373903-eme-logger" rel="nofollow">EME Logger Script</a> (installed on <a title="Tampermonkey" href="https://www.tampermonkey.net/" rel="nofollow">Tampermonkey</a> add-on) will give you init data. That's your PSSH. This can be found on Developer Tools (ctrl + shift + c) &gt; Console, in the filter bar search for <code>MediaKeySession::generateRequest</code> you will find Init Data.</li>
</ol>
Optional, may be rquired:
If that Init Data is very very long, convert it to HEX: <a href="https://base64.guru/converter/decode/hex" rel="nofollow">https://base64.guru/converter/decode/hex</a>
Here's what mine looked like before conversion. <a title="Two" href="https://cdm-project.com/How-To/Obtaining-PSSH/media/branch/main/example_two.png?raw=true" target="_blank" rel="nofollow noopener"><img title="Two" src="https://cdm-project.com/How-To/Obtaining-PSSH/media/branch/main/example_two.png?raw=true" alt="Two:" /></a>
After Base64 &gt; HEX conversion, you will find a Widevine-PSSH box, this can be found easily by searching with ctrl + f and searching for <code>70737368</code>
PSSH header is always in a <code>000000xx70737368</code> where the <code>xx</code> is varied and can be from 1-9 in both x spots. You always want to copy the 6 <code>0</code>'s before the xx as well.
Example: <a title="Three" href="https://cdm-project.com/How-To/Obtaining-PSSH/media/branch/main/example_three.png?raw=true" target="_blank" rel="nofollow noopener"><img title="Three" src="https://cdm-project.com/How-To/Obtaining-PSSH/media/branch/main/example_three.png?raw=true" alt="Three:" /></a>
The end of the header is always then followed by 8 more <code>0</code>s, if you see this, you are in the right place.
Once you find the header start at the beginning 0 from the header and copy until the end of the converted hex, it should look like this
Example: <a title="Four" href="https://cdm-project.com/How-To/Obtaining-PSSH/media/branch/main/example_four.png?raw=true" target="_blank" rel="nofollow noopener"><img title="Four" src="https://cdm-project.com/How-To/Obtaining-PSSH/media/branch/main/example_four.png?raw=true" alt="Four:" /></a>
In this case the full value was <code>000000577073736800000000edef8ba979d64acea3c827dcd51d21ed0000003708011210162f7d326cf24f6dbd1319bc572bbc151a0b62757964726d6b65796f732210162f7d326cf24f6dbd1319bc572bbc152a024844</code>
convert the hex back into base64 using <a href="https://base64.guru/converter/encode/hex" rel="nofollow">https://base64.guru/converter/encode/hex</a>
Example: <a title="Five" href="https://cdm-project.com/How-To/Obtaining-PSSH/media/branch/main/example_five.png?raw=true" target="_blank" rel="nofollow noopener"><img title="Five" src="https://cdm-project.com/How-To/Obtaining-PSSH/media/branch/main/example_five.png?raw=true" alt="Five:" /></a>
In this case we got the PSSH value of <code>AAAAV3Bzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAADcIARIQFi99MmzyT229Exm8Vyu8FRoLYnV5ZHJta2V5b3MiEBYvfTJs8k9tvRMZvFcrvBUqAkhE</code>
Congrats, you have the PSSH!
