Data Science, Machine Learning, Deep Learning, and Artificial intelligence are really hot at this moment and offering a lucrative career to programmers with high pay and exciting work.

It's a great opportunity for programmers who are willing to learn these new skills and upgrade themselves and want to solve some of the most interesting real-world problems.

It's also important from the job perspective because Robots and Bots are getting smarter day by day, thanks to these technologies, and most likely will take over some of the jobs which many programmers do today.

Hence, it's important for software engineers and developers to upgrade themselves with these skills. Programmers with these skills are also commanding significantly higher salaries as data science is revolutionizing the world around us.

You might already know that the Machine learning specialist is one of the tops paid technical jobs in the world. However, most developers and IT professionals are yet to learn this valuable set of skills.

For those, who don't know what is a Data Science, Machine learning, or deep learning, they are very related terms with all pointing towards machine doing jobs which is only possible for humans till date and analyzing the huge set of data collected by the modern-day application.

Data Science, in particular, is a combination of concepts such as machine learning, visualization, data mining, programming, data mugging, etc.

If you have some programming experience then you can learn Python or R to make your carer as a Data Scientist.

There are a lot of popular scientific Python libraries such as Numpy, Scipy, Scikit-learn, Pandas, TensorFlow, PyTorch which is used by Data Scientist for analyzing data.

To be honest with you, I am also quite new to Data Science and Machine learning world but I have been spending some time from last year to understand this field and have done some research in terms of the best resources to learn machine learning, data science, etc.

I am sharing all those resources in a series of blog posts like this. Earlier, I have shared some courses to learn TensorFlow, one of the most popular machine-learning library, and today I'll share some more to learn these technologies.

These are a combination of both free and paid resources which will help you to understand key data science concepts and become a Data Scientist. Btw, I'll get paid if you happen to buy a course which is not free.

10 Best Courses to Learn Machine Learning and Data Science for Beginners

Here is my list of some of the best courses to learn Data Science, Machine learning, and deep learning using Python and R programming language. As I have said, Data Science and machine learning work very closely together, hence some of these courses also cover machine learning.

If you are still on the fence with respect to choosing Python or R for machine learning, let me tell you that both Python and R are a great language for Data Analysis and have good APIs and library, hence I have included courses in both Python and R, you can choose the one you like.

I personally like Python because of its versatile usage, it's the next best in my list of language after Java. I am already using it for writing scripts and other web stuff, so it was an easy choice for me. It has also got some excellent libraries like Sci-kit Learn and TensorFlow.

Data Science is also a combination of many skills like Data visualization, data cleaning, data mining, Data Analysis, etc and these courses provide a good overview of all these concepts and also present a lot of useful tools that can help you in the real world.

Machine Learning Specialization by Andrew Ng

This is probably the most popular online course to learn machine learning provided by Stanford University and Coursera, which also now provides certification.

You'll be tested on each and every topic that you learn in this course, and based on the completion and the final score that you get, you'll also be awarded the certificate.

This course is free but you need to pay for certificates if you want. Though, it does provide value to you as a developer and gives you a good understanding of the mathematics behind all the machine learning algorithms that you come up with.

I really liked this course. Andrew Ng takes you through the course using Octave, which is a good tool to test your algorithm before making it go live on your project.

By the way, If you are planning to join multiple Coursera courses or specializations, then consider taking a Coursera Plus subscription which provides you unlimited access to 700+ courses, specialization, professional certificate, and guided projects.

Now, let's see 10 best online courses you can join to learn Data Science and Machine Learning today:

1.Machine Learning A-Z: Hands-On Python and R --- In Data Science

This is probably the best hands-on course on Data Science and machine learning online. In this course, you will learn to create Machine Learning Algorithms in Python and R from two Data Science experts.

This is a great course for students and programmers who want to make a career in Data Science and also Data Analysts who want to level up in machine learning.

It's also good for any intermediate-level programmers who know the basics of machine learning, including the classical algorithms like linear regression or logistic regression, but who want to learn more about it and explore all the different fields of Machine Learning.

2. Data Science with R by Pluralsight

Data science is the practice of transforming data into knowledge, and R is one of the most popular programming language used by data scientists.

In this course, you'll learn first learn about the practice of data science, the R programming language, and how they can be used to transform data into actionable insight.

Next, you'll learn how to transform and clean your data, create and interpret descriptive statistics, data visualizations, and statistical models.

Finally, you'll learn how to handle Big Data, make predictions using machine learning algorithms, and deploy R to production.

Btw, you would need a Pluralsight membership to get access to this course, but if you don't have one you can still check out this course by taking their 10-day free Pass, which provides 200 minutes of access to all of their courses for free.

3. Harvard Data Science Course

The course is a combination of various data science concepts such as machine learning, visualization, data mining, programming, data mugging, etc.

You will be using popular scientific Python libraries such as Numpy, Scipy, Scikit-learn, Pandas throughout the course.

I suggest you complete the machine learning course on course before taking this course, as machine learning concepts such as PCA (dimensionality reduction), k-means, and logistic regression are not covered in depth.

But remember, you have to invest a lot of time to complete this course, especially the homework exercises are very challenging

In short, if you are looking for an online course in data science(using Python), there is no better course than Harvard's CS 109. You need some background in programming and knowledge of statistics to complete this course.

4.An Introduction to Data Science on Udemy? (FREE)*

This is a great introductory course on what Data scientists do and how you can become a data science professional. It's also free and you can get it on Udemy.

If you have just heard about Data Science and excited about it but don't know what it really means then this is the course you should attend first.

It's a small free data science course but packed with big punches. You will understand what Data Science is? Appreciate the work Data Scientists do on a daily basis and differentiate the various roles in Data Science and the skills needed to perform them.

You will also learn about the challenges Data Scientists face. In short, this course will give you all the knowledge to make a decision on whether Data Science is the right path for you or not.
