Learning every facet of data science takes time. We have written pieces on different resources before. But we really wanted to focus on courses, or video like courses on youtube.

There are so many options, it can be nice to have a list of classes worth taking.

We are going to start with the free data science options so you can decide whether or not you want to start investing more in courses.

Tip : Coursera can make it seem like the only option is to purchase the course. But they do have an audit button on the very bottom. Now, if you appreciate Coursera, by all means, you should purchase their specialization, I am still uncertain how I feel about it. But, I do love taking Coursera courses.

12. Machine Learning A-Z™: Hands-On Python & R In Data Science

This course is comprehensive and discusses both Python and R. This isn’t just focused on Scikit learn but machine learning in general. In addition, the creator of this course is the owner of SuperDataScience.com this is a great site with a podcast, lessons and more. So if you don’t want to pay for the course, you can always listen to the podcasts for free!

Python, of course, is not the only language for data science. Another popular language is R (also, these aren’t the only 2 languages, there are other languages people like to use…except Matlab..we don’t talk about Matlab)

Review: Machine Learning A-Z is a great introduction to ML. A big tour through a lot of algorithms making the student more familiar with scikit-learn and few other packages…. ML-az is a right course for a beginner to get the motivation to dive deep in ML.

13. Machine Learning, Data Science and Deep Learning with Python

Frank Kane has another great course on this topic where he will cover more than the book mentioned above. He will also discuss Ensemble Learning and bias trade-offs. Plus, if you are a visual learner, this will probably benefit you more. There’s also an entire section on machine learning with Apache Spark, which lets you scale up these techniques to “big data” analyzed on a computing cluster.

14. Data Science A-Z™: Real-Life Data Science Exercises Included

The previous  Kirill Eremenko course we mentioned was more comprehensive and theoretical. It didn’t go into the process of data science. This course instead goes through several tools that are used by data scientists and BI engineers. This course is mixed with a little BI, but practically, a lot of “data science” roles require BI skills. So depending on the company and role you are looking for, this is a great fit.

Review: It is an excellent course for people who are super excited about data science. But I would say this course should include R or Python Exercises as well. Data Visualization, Data preparation and Data Communication parts are awesome but data modeling section is a bit weak in the sense that it does not have an impact on real-world problems but this part of the course needs Improvement. However, the course engaging and you learn a lot from it after completing it.

15. Deep Learning A-Z™: Hands-On Artificial Neural Networks

OK, let’s say you really are interested in deep learning and not data science. Well then this course is a great overall.

As it discusses, Artificial intelligence is growing exponentially. There is no doubt about that. Self-driving cars are clocking up millions of miles, IBM Watson is diagnosing patients better than armies of doctors and Google Deepmind’s AlphaGo beat the World champion at Go – a game where intuition plays a key role.

But the further AI advances, the more complex become the problems it needs to solve. And only Deep Learning can solve such complex problems and that’s why it’s at the heart of Artificial intelligence

Inside this class we will work on Real-World datasets, to solve Real-World business problems. (Definitely not the boring iris or digit classification datasets that we see in every course). In this course we will solve six real-world challenges:

  • Artificial Neural Networks to solve a Customer Churn problem
  • Convolutional Neural Networks for Image Recognition
  • Recurrent Neural Networks to predict Stock Prices
  • Self-Organizing Maps to investigate Fraud
  • Boltzmann Machines to create a Recommender System
  • Stacked Auto-encoders* to take on the challenge for the Netflix $1 Million prize

Automation And Operational Python

Not everyone interested in data science, want to be researchers. Some people want to be more developers, engineers. This arguably a very different data scientist types, some people just prefer building, automating and developing. This is a very valuable trait to have as a data scientist because you can play an important role in your group of automating a lot of the work that needs to get done.

In order to do that, you will need to have a solid understanding of a scripting language.

16. Python Automation for Everyone || Learn Python 3

This course is designed for both absolute beginners or people with some programming experience looking to learn Python which is one of the highest in-demand skill by employers in IT industry. The key point which makes this course unique is that it is fast yet detailed. This course provides sufficient details to you to design and develop your own Python solution. Unlike many other Python courses, This course is concise and you can complete it over a weekend.

17. Master the Coding Interview: Data Structures + Algorithms

Something like python, but not the kind we referred to earlier which was focused on libraries like Pandas and Scikit learn. Instead, we are referring to operational python. This usually requires a general understanding of data structures like hash-maps, loops, file system management, etc. This is where the course below comes in handy. It will provide a good basis for your programming skill set.

Youtube Tutorials And “Courses”

Let’s say you don’y want to pay for a course. That is fine. Again, these courses will never replace experience, they merely provide a good basis. Some people seem to need to pay for things in order to feel motivated to finish the course. But youtube has lots of great options. So We wanted to lay out a few options for free.

Now, we do want to provide a caveat, and it has been brought up by the ex-google tech lead Patrick on his youtube channel. Don’t spend all your time starting new tutorials. Do one or two, get the basics down and then start looking for projects. While you are doing those projects you should learn how to use resources like API documentation, and problem specific videos to improve your skills.

Otherwise, you will never really progress in your skill set. You will essentially just be spending your time relearning the abcs over and over again and never learning about words, sentences, paragraphs, essays, etc.

18. Python OOP Tutorial 1: Classes and Instances

If you are looking for a set of videos that teaches about object oriented programming and also data structures and algorithms then consider checking out Corey Schafer channel. He does a great job of having a pretty complete set of videos that pretty much covers everything you could learn from the first few pages of the python library online. This is great for learning how to build automated

19. CS Dojo Python And More

Another great channel on youtube that will not just help you with tutorials but will also provide some more problem specific videos (vs general tutorials) is the CS Dojo. This channel covers everything from interviewing, coding, design, etc. It is a great channel if you really want to learn programming and want to get a job. Again, not all data scientists want to know python and programming, but some do. There is value in knowing it if that is the style of data scientist you want to be.
