The specialization consists of 3 courses series, including supervised learning (multiple linear regression, logistic regression, neural networks, and decision trees), unsupervised learning (clustering, dimensionality reduction, recommender systems), and some of the best practices used in Silicon Valley for artificial intelligence and machine learning innovation (evaluating and tuning models, taking a datacentric approach to improving performance, and more.)
The courses are taught through a combination of video lectures, quizzes, programming assignments, and a final project. Learners will use Python programming language and the opensource machine learning library, scikitlearn, to implement the algorithms and build predictive models.
The specialization is suitable for learners with some programming experience and a basic understanding of mathematics, including linear algebra and calculus. However, the courses are designed to be accessible to learners from a wide range of backgrounds and levels of experience.
By the end of this Specialization, you will have mastered key concepts and gained the practical knowhow to quickly and powerfully apply machine learning to challenging realworld problems. If you’re looking to break into AI or build a career in machine learning, the new Machine Learning Specialization is the best place to start.

Reviews:
As a former learner of the Machine Learning Specialization on Coursera, I can attest to the high quality of the program. The specialization consists of 3 courses that cover a wide range of topics, from supervised and unsupervised learning to deep learning and neural networks. Each course is designed to build on the material covered in the previous course, providing learners with a comprehensive introduction to machine learning.
One of the strengths of the program is the quality of the teaching. Andrew Ng, the author of the course, is a renowned expert in the field of machine learning, and his lectures are engaging, clear, and informative. He has a talent for breaking down complex concepts into understandable parts, making the material accessible to learners with different levels of prior knowledge. In addition to the video lectures, the program also includes readings, quizzes, and programming assignments, which reinforce the concepts covered in the lectures and provide learners with handson experience working with realworld datasets.
The programming assignments and projects are a standout feature of the program. They are challenging and require learners to apply the concepts they have learned to solve real problems. The projects are particularly valuable, as they give learners the opportunity to work on largerscale problems and apply multiple techniques and algorithms to real datasets. The feedback on assignments and projects is also very helpful, providing learners with guidance on how to improve their code and approach to problemsolving.
Another strength of the program is the community. The specialization has a large and active community of learners, with discussion forums where learners can ask questions, share their work, and collaborate on projects. The community is a valuable resource for learners, providing them with the opportunity to connect with others who are interested in machine learning and learn from their experiences.
Overall, I found the Machine Learning Specialization to be an outstanding program that provided me with a strong foundation in machine learning. The program is rigorous but accessible, and the quality of the teaching and material is exceptional. I would highly recommend this program to anyone interested in learning about machine learning, whether they are just starting out or looking to deepen their knowledge.
At this time, the course has an average rating of 4.9 out of 5 stars based on over 10,499 ratings.
