8 Best Deep Learning Courses to Learn Online in 2021

Deep learning is a powerful machine learning technique based on neural networks with feature learning. It now has infinite practical applications in every industry, including speech/image recognition, mobile advertising, medical image analysis, and many more.

As of 2021, deep learning has become the basis of modern AI development. More and more companies need experts in this field to help build powerful AIs of their own.

Because the skill is extremely in demand, deep learning is inevitably a lucrative skill. According to Indeed, deep learning engineers earn a base salary of $131,229 per year in the United States. This number might increase even further within a few years,

Undoubtedly, if you want a high-earning career in tech with excellent prospects, deep learning is 100% worth learning.

Learning the fundamentals of deep learning online is plausible. However, not every course is high-quality and worth the investment.

Hence, I decided to conduct independent research and provide you a list of the 8 best deep learning courses in this post. This is to help you comfortably choose the one that suits your preferences.

Things You Should Know

What are the prerequisites?

Deep learning is not for beginners. Beginners cannot learn deep learning without background knowledge.

However, you do not need a master’s degree in computer science to learn deep learning. Still, you will need a good understanding of these subjects as follows.

Before taking any course on deep learning, your Python programming skills need to be intermediate or higher. In other words, you should have taken at least one Python for Data Science course before.

Besides Python, other programming languages (C++/JavaScript/Java) are NOT needed for learning deep learning. However, former hands-on experience in machine learning techniques would be beneficial.

6. Lazy Programmer’s Deep Learning Courses

Lazy Programmer, a highly knowledgeable AI and machine learning engineer, has created a dozen deep learning courses on Udemy. I have taken some of these courses and realized that they are in-depth and practical. Thus, I decided to recommend him to you.

Lazy Programmer’s Course

Course Content

As indicated above, Lazy Programmer has more than a dozen courses in deep learning. Below are some that I believe most learners may be interested in.

Data Science and Neural Networks in Python – This course will teach you the fundamentals of deep learning, including how deep learning works, how the model is built, and different types of neural networks.

The instructor will go through several unsupervised neural networks, such as the autoencoder and Restricted Boltzmann Machines (RBMs). You will understand how they work and how to put them to proper use.

Length: 10.5 hours , Ratings 4.7/5.0, 17,300+ students

Deep Learning: Convolutional Neural Networks in Python – This course is a deep dive on CNNs or convolutional neural networks.

After you complete the entire course material, you will be able to explain their architecture by heart, create them on Tensorflow and apply them to NLP for text classification.

Length: 12 hours, Ratings 4.6/5.0, 25,900+ students

Deep Learning: Recurrent Neural Networks in Python – This course will focus on RNNs (Recurrent Neural Networks.) You will learn to build them on Tensorflow and apply them to image classification, stock price prediction, and spam detection (NLP.)

You need to purchase these courses separately. As these are Udemy courses, I recommend buying them at a discount when they are on sale. Thus, each will cost you less than $15.

Absence of Course Order

Many students, including me, find Lazy Programmer’s courses hard-to-reach as the entire series lacks a proper order, so we don’t know which courses to take in succession. Lazy Programmer’s plan to create more courses could make the series even fuzzier.

In fact, to solve the problem, Lazy Programmer has provided a lengthy guide on it. Still, I don’t think this guide is the solution, as learners have dissimilar backgrounds.

Hence, my advice is if you are new to deep learning, you may want to take the first course elsewhere. Andrew Ng’s, IBM’s, and Kirill’s are solid options.

Subsequently, if you want to enhance your knowledge on specific deep learning topics, you can then purchase one or more of Lazy Programmer’s courses. Thus, an absence of the course order will not bother you at all.

Different courses from Lazy Programmer have different prerequisites. Some may even require knowledge of Tensorflow or Theano. Therefore, it is vital to read the requirements section on the Udemy sales page very carefully.

Pros and Cons


  • The instructor is highly knowledgeable. He emphasizes “how to use” and the logic and understanding behind each concept or deep learning tool.
  • In-depth video course
  • Crystal – clear explanations
  • Frequently updated
  • Lifetime access
  • Inexpensive ($10-$15 per course when the Udemy platform has a sales event.)
  • 30-day money-back guarantee


  • Purchasing all courses could still cost more than $100, even if you buy them all when they are on sale.
  • Unorganized series. You need to choose the courses and sort them on your own.
  • Lazy Programmer reuses some content. Thus, it is possible that two different courses from him could have parts that are the same.

7. Deep Learning and Neural Networks for Financial Engineering

Those in quantitative finance will find this training program by New York University on edX highly beneficial.

This program will teach you deep learning and neural networks as other courses. However, all examples and case studies are from finance. Thus, it is effortless for finance professionals to apply the knowledge to use.
