If deep learning is your preferred niche, then this is an excellent course for you to take.
You’ll get to learn about:
This course builds on the instructor’s previous course titled machine learning so you may miss a few ideas if you jump into it straight away. However, even if you didn’t take the class leading up to this one, you can still sufficiently follow through as a stand-alone course.
Would you like to take your Python skills to the next level?
For advanced Python learning, this class offers excellent techniques and toolsets and is the best data science course on Coursera for leveling up.
Course highlights include:
This course builds on a basic understanding of Python, so if you’re a complete beginner, it may not be among the best data science courses online for you. On the other hand, if you’d just like to dive into the core of data structures and speed through some of the basics, it’s an excellent choice.
This is the best data science course on Coursera if you’re new to data science and Python, but would like to combine both.
You can expect the following from the course:
On the downside, the takeaway assignments are a lot more difficult than the in-class examples. However, this makes it one of the best online data science courses as it urges you to think outside the box.
Good data analytics drive intelligent business decisions and this is one of the best data science tutorials to get you acquainted with the skills you need.
Lesson highlights encompass:
