Best Online Courses on Data Structures and Algorithms for Data Science & Machine Learning

As the buzz around data science and machine learning grows every day, there are a lot of self-taught folks who have kick-started the machine learning journey with online courses on data science and machine learning & AI. Those who are not from Computer Science background and want to pursue a career in data science or machine learning, they need to be familiar with mathematics, linear algebra, calculus, algorithms, statistics, and data structures. In this post, we have aggregated a curated list of most popular and best online courses on Mathematics, Algorithms, Data Structures & Statistics for Data Science and Machine Learning.

It’s tough to learn much of anything by just reading a Data Science or ML/AI book. Well, you gotta be pretty good at math to understand everything. So, my suggestion is to enroll in some Maths/stats, Algorithms, Data Structure course, and start working on basics.

MOOCs and online courses are useful to jump start. After you do a MOOC though you have to continue with doing real work as in exercises, Kaggle competitions and just playing with things.

Ruby on Rails – Johns Hopkins University

Ratings: 4.5

Students Enrolled: 71K+

As Machine Learning is a part of Data Science it is a composition of various mathematical computations. It means that an application using the technology needs to provide complex calculations, fast. 

Like any other web application framework, Ruby-on-Rails (ROR) is also a server-side web application framework written under the MIT license for developing robust web applications. 

Ruby on Rails has been a preferred choice for the developers because it assists with task automation, which is a blessing in the technology world.

The famous Ruby on Rails Web Services used worldwide are: Basecamp, Kickstarter, Airbnb, GitHub, ASKfm, Couchsurfing, SlideShare, etc. to name a few. These are all successful web application frameworks that are used by millions of people worldwide.

In this course, we will explore how to build web applications with the Ruby on Rails web application framework, which is geared towards rapid prototyping. Yes, that means building quickly! At the conclusion of this course, you will be able to build a meaningful web application and deploy it to the “cloud” using a Heroku PaaS (Platform as a Service).

Sign up for this course.

Note: Ruby is not an ideal choice for machine learning processes. But, Ruby is actually a good choice for user interaction and API functions.

As with the help of the ROR framework, the developers can create MVPs in a better and faster way; the framework is highly recommended for creating beautiful web frameworks and services. But when it comes to Machine Learning with Ruby on Rails is not justified enough.

The best alternative for ML would be Python.
