Our take
Based on the ratings of 206,030 students, a sample of their written reviews and the syllabus, as the course stood in June 2026. No course pays to be reviewed.
Kirill Eremenko and Hadelin de Ponteves built this as a survey of the field: regression, classification, clustering, association rules, reinforcement learning, NLP and neural networks, plus an AWS track covering SageMaker, deployment and CI/CD pipelines. It runs about 49 hours across 474 lectures, and the syllabus lets students follow the Python, R or AWS path and skip the rest. First published in 2016, it was refreshed in June 2026. The target is beginners with high school math who want breadth before depth. With 1.2 million students and a 4.5 rating from about 206,000 reviews, it is one of the biggest machine learning courses on Udemy.
Reviewers consistently praise the theory lectures. The intuition-first explanations with diagrams get credit for making hard concepts stick, and beginners say it's easy to follow with no prior ML knowledge. The complaints cluster around the coding videos. Several reviews call them padded, with minutes of preamble before two lines of code, and one reviewer estimates a quarter of the runtime could go. Others say some Python snippets are deprecated, the graded labs fail on variable names, and the dataset links are hard to find. A few three-star reviews want more statistics and more checking of each model's assumptions.
It sits beside the Python for Data Science and Machine Learning Bootcamp in our Python and machine learning lists, and the pitch here is breadth: a map of the field in Python and R, with AWS on top, rather than deep fluency in one library. One reviewer also found one of the two instructors hard to listen to, so try the videos at 1.5x speed if the padding bothers you. As a first pass at machine learning, refreshed in 2026, it's an easy recommendation. For rigor, pair it with a statistics text.
Pros
- Theory lectures explain each algorithm with diagrams and intuition; reviewers say the concepts stick.
- Covers regression through neural networks, plus an AWS track on SageMaker, deployment and CI/CD.
- Python and R tracks can be taken separately, with code templates included for the models.
- Refreshed in June 2026 and backed by 1.2 million students and a 4.5 rating from 206,000 reviews.
Cons
- Coding videos are padded with long intros; one reviewer estimates a quarter of the runtime could be cut.
- Some Python snippets are deprecated and the graded labs fail on variable names, per recent reviews.
- Shallow on statistics; model assumptions are rarely checked, so it can feel like a coding tutorial.
This one with very practical hands on tests, with great logical explanations for each line of code is terrific
Marked All Levels, but it's really a first course: high school math is enough, and coding beginners can lean on the templates.

I can tell that the instructirs have a lot of real experiences. I tried couple of ML trainings, including the expensive ones, which didnt work for me. This one with very practical hands on tests, with great logical explanations for each line of code is terrific
By Mohd Sifat Khan on 8/21/2026
The length of videos are short and OK. It allows to take a brake and complete one video quickly especially when u have other activities in hand. However the content is very superficial and lacks depth in both statistical aspects and coding aspect. At least distinction between coding and ML should be emphatically presented which i think is the biggest downside of the course. It just feels like learning how to code. It meets the expectation of beginner.
By 283 Nishaad Mhatre on 7/16/2026
The theory explanation using diagrams is an excellent idea, it helped me understand a lot of complex concepts. The code implementation from scratch also helped me hone my coding skills, overall it's a very good course.
By Anilesh Mathur on 7/10/2026
Great course! The explanations are clear, the examples are easy to understand, and it's perfect for beginners. I would definitely recommend it to anyone starting their learning journey.
By Ulises Pappalardo on 6/28/2026
The labs work horribly. First as an example, I was asked to do something on a lab that I had not seen yet. Still, the worst part is how the lab fails you because of random things. If a variable has a different name than expected or if the size of X is not what it expects (sometimes it expects the wrong size). Sometime you don't even know which variable it is testing, as it doesn´t clarify. To top this, you don't have the possibility to see the output of your code.

one of few courses where the author is directly getting to the point instead of beating around the bush . he teaches what is necessary without wasting time on useless things... recommend him ..
By Aditya Kini on 5/27/2026
The association rule learning part was a bit unclear,i.e the explanation wasnt good enough imo. The other parts were much better compared to that.
By Ahmad Faraz on 5/24/2026
The course covers all the essentials for ML beginners, and I especially appreciate how each algorithm and model is explained. The simplification of mathematical concepts, along with visual representations, makes everything much easier to understand. This approach really helps the information stay with me longer. I expect to complete it within the next two weeks and am currently on week 2.

more learned ,more benefit for artificial intelligents and machine learning student ; thank you giving very video good understanding .
By Manisha Gade on 1/27/2026
The course helped me understand key concepts clearly and improved my analytical thinking. The combination of theory and practical examples made learning interesting and effective. Overall, the course has strengthened my foundation and increased my confidence in the subject.
