How to Learn Data Science for Free
If you do have some money to put towards learning then I strongly suggest putting it towards paying for a few months of the premium subscription.
After that, I would suggest building some practical machine learning applications and learning the theory behind how the models work — which I will cover a bit later on.
SQL SQL is a vital skill to learn if you want to become a data scientist as one of the fundamental processes in data modelling is extracting data in the first place.
There is a free tier so you can try queries for free, an extensive range of public datasets to try and very good documentation.
It is probably worth noting here that similar to Dataquest Codeacademy also offers a complete data science learning plan as part of their pro account (this costs from $31.99 to $15.99 per month depending on how many months you pay for up front).
I personally found the Dataquest course to be much more comprehensive but this may work out a little cheaper if you are looking to follow a learning path on a single platform.
Additionally, when you start to put models into production you will need to be able to write good quality well-tested code and work with tools like version control.
The scikit-learn contribution guidelines, although written to facilitate contributions to the library, actually cover the best practices really well.
For a comprehensive introduction to deep learning, I don’t think that you can get any better than the totally free and totally ad-free fast.ai.
This course includes an introduction to machine learning, practical deep learning, computational linear algebra and a code-first introduction to natural language processing.
