Everyone interested in machine learning has heard of Andrew Ng: one of the most respected people in the AI world.
We wrote about him in our article on the Top AI Influencers To Follow In 2022. Here, we’ll focus more on his AI courses, particularly the one on ML (one of the most popular and highly-rated Machine Learning online courses around).
Once complete, you’ll know all about machine learning, statistics, neural networks, and data mining.
The course covers the following:
- Supervised learning
- Unsupervised learning
- Best practices in machine learning
Andrew includes several case studies to help you see how to apply your new skills in the real world, but one thing.
While the AI course is free, you have to pay for the final certificate.

As you may know, machine learning is used in Data Science, and it’s one of the 5 Most In-Demand Skills for a Data Scientist.
That’s why it helps to know the fundamentals of ML and the different learning algorithms before you do any data science work. The following Data Science course run by Rafael Irizarry, Professor of Biostatistics at Harvard University, is all about that.
In this interesting course, you’ll learn:
- The basics of ML
- How to perform cross-validation to avoid overtraining
- The most popular machine learning algorithms
- How to build a recommendation system
- What is regularization, and why is it useful?
- What is data analysis?
- How to train data to obtain valuable insights
The artificial intelligence course itself is free. However, the exam and the certificate cost $99 — but it is from Harvard, so it’s worth it, right?

According to GitHub, Python is the most popular programming language used in machine learning. That’s why you should consider learning how to apply it in ML projects, and this Machine Learning in Python course can help you with that.
The course’s main goal is to show you how to use Python, one of the most popular and approachable programming languages, in ML. Under Dr. Saeed Aghabozorgi, Senior Data Scientist at IBM, you’ll run through the following five modules of the free ML course:
- Introduction to Machine Learning: ML applications, supervised vs. unsupervised learning, Python libraries suitable for ML
- Regression: linear, non-linear, and model evaluation methods
- Classification: K-Nearest neighbor, decision trees, logistic regression, support vector machines, and model evaluation
- Unsupervised Learning: K-Means, hierarchical and density-based clustering
- Recommender Systems: Content-based recommender systems and collaborative filtering
Once finished, you’ll understand the difference between the two main types of machine learning methods, the various ML algorithms, and how statistical modeling relates to ML (as well as how to compare them).
Moreover, you’ll know how to transform theoretical knowledge into practical skills.

We know some of you are familiar with the basics, so let’s move on to more advanced Machine Learning and Artificial Intelligence courses. Google runs this one, and you can choose between two paths.
The first is for Data Scientists / Machine Learning Engineers, consisting of eight parts:
- Big Data & Machine Learning Fundamentals
- Perform Foundational Data, ML, and AI Tasks in Google Cloud
- Machine Learning on Google Cloud
- Advanced Machine Learning with TensorFlow on Google Cloud Platform
- MLOps (Machine Learning Operations) Fundamentals
- ML Pipelines on Google Cloud
- Explore Machine Learning Models with Explainable AI
- Build and Deploy Machine Learning Solutions on Vertex AI
The second is dedicated to Contact Center Engineers, offering a shorter AI course made up of just three elements:
- Customer Experiences with Contact Center AI
- Automate Interactions with Contact Center AI
- Create Conversational AI Agents with Dialogflow CX
Following each course, you’ll be able to implement the latest ML and AI solutions by exploring training on TensorFlow, Natural Language API, Cloud Vision, and more.
These skills are a must-have if you plan to work with Google Cloud.
