• What is machine learning?

  Machine learning is a branch of artificial intelligence that enables algorithms to automatically learn from data without being explicitly programmed. Its practitioners train algorithms to identify patterns in data and to make decisions with minimal human intervention.

  In the past two decades, machine learning has gone from a niche academic interest to a  central part of the tech industry. It has given us self-driving cars, speech and image recognition, effective web search, fraud detection, a vastly improved understanding of the human genome, and many other advances. Amid this explosion of applications, there is a shortage of qualified data scientists, analysts, and machine learning engineers, making them some of the world’s most in-demand professionals.

• What is the Machine Learning Specialization about?

  The Machine Learning Specialization is a foundational online program created in collaboration between DeepLearning.AI and Stanford Online. This beginner-friendly program will teach you the fundamentals of machine learning and how to use these techniques to build real-world AI applications. 

  This Specialization is taught by Andrew Ng, an AI visionary who has led critical research at Stanford University and groundbreaking work at Google Brain, Baidu, and Landing.AI to advance the AI field.

  This 3-course Specialization is an updated version of Andrew’s pioneering Machine Learning course, rated 4.9 out of 5 and taken by over 4.8 million learners since it launched in 2012. 

  It provides a broad introduction to modern machine learning, 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 data-centric approach to improving performance, and more.)

  By the end of this Specialization, you will have mastered key concepts and gained the practical know-how to quickly and powerfully apply machine learning to challenging real-world 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.

• What will I learn in the Machine Learning Specialization?

  By the end of this Specialization, you will be ready to

   

  • Build ML models with NumPy & scikit-learn, build & train supervised models for prediction & binary classification tasks (linear, logistic regression)

  • Build and train a neural network with TensorFlow to perform multi-class classification.

  • Apply best practices for machine learning development so that your models generalize to data and tasks in the real world.

  • Build and use decision trees and tree ensemble methods, including random forests and boosted trees.

  • Use unsupervised learning techniques for unsupervised learning including clustering and anomaly detection.

  • Build recommender systems with a collaborative filtering approach and a content-based deep learning method.

  • Build a deep reinforcement learning model.

• What background knowledge is necessary for the Machine Learning Specialization?

  Learners should understand basic coding (for loops, functions, if/else statements) and high school-level math (arithmetic, algebra). Any additional math concepts will be explained along the way.

• Who is the Machine Learning Specialization for?

  The Machine Learning Specialization is a beginner-level program aimed at those new to AI and looking to gain a foundational understanding of machine learning models and real-world experience building systems using Python. 

  This Specialization is suitable for learners with some basic knowledge of programming and high-school level math, as well as early-stage professionals in software engineering and data analysis who wish to upskill in machine learning.

• How long does it take to complete the Machine Learning Specialization?

  This Specialization consists of three courses. At the rate of 5 hours per week, it will take 3 weeks to complete Course 1, 4 weeks to complete Course 2, and 3 weeks to complete Course 3 of the Machine Learning Specialization.

• Who created the Machine Learning Specialization?

  This Specialization was created by Andrew Ng, Eddy Shyu, Aarti Bagul, and Geoff Ladwig. 

  Andrew Ng is the Founder of DeepLearning.AI, Founder and CEO of Landing AI, Chairman and Co-founder of Coursera, and an Adjunct Professor at Stanford University. Dr. Ng has changed countless lives through his work, authoring or co-authoring over 200 research papers in machine learning, robotics, and related fields. He was the founding lead of the Google Brain team and Chief Scientist at Baidu, and through this work built the teams that led the AI transformation of two leading internet companies. He is the co-founder and Chairman of Coursera — the world's largest online learning platform — which had started with his machine learning course. Dr. Ng now focuses primarily on his entrepreneurial ventures, looking for the best ways to accelerate responsible AI practices in the larger global economy. 

  Eddy Shyu is a product lead at DeepLearning.AI and has led the teams that built the Machine Learning Specialization (featuring Andrew Ng), TensorFlow Advanced Techniques (featuring Laurence Moroney), as well as the Natural Language Processing Specialization, and AI for Medicine Specialization. Eddy was also co-instructor for Udacity's AI for Trading Nanodegree program.

  Aarti Bagul is a machine learning engineer at Snorkel AI. Before Snorkel, she worked closely with Andrew Ng in various capacities: At the AI Fund, she helped build and invest in machine learning companies. Previously, she was a machine learning engineer at Landing AI and was the head teacher’s assistant for Dr. Ng’s deep learning class at Stanford University. She graduated with a Master's in Computer Science from Stanford and a Bachelor's in Computer Science and Computer Engineering from NYU with the highest honors.

  Geoff Ladwig started as a Deep Learning student and a mentor for the Deep Learning Specialization. He worked as a consultant on the Natural Language Processing Specialization and as a Curriculum Engineer on the Machine Learning Specialization. Geoff has spent most of his career as an ASIC/Hardware/System engineer/architect in the communications and computer industries.

• What makes the Machine Learning Specialization so unique?

  The Machine Learning Specialization is a foundational online program taught by Andrew Ng, an AI visionary who has led critical research at Stanford University and groundbreaking work at Google Brain, Baidu, and Landing.AI to advance the AI field.

  This 3-course Specialization is an updated and expanded version of Andrew’s pioneering Machine Learning course, rated 4.9 out of 5 and taken by over 4.8 million learners since it launched in 2012. 

  This program has been designed to teach you foundational machine learning concepts without prior math knowledge or a rigorous coding background. Unlike the original course, which required some knowledge of math, the new Specialization aptly balances intuition, code practice, and mathematical theory to create a simple and effective learning experience for first-time students. 

  Each lesson begins with a visual representation of machine learning concepts and a high-level explanation of the intuition behind them. It then provides the code to help you implement these algorithms and additional videos explaining the underlying math if you wish to dive deeper. These lessons are optional and are not required to complete the Specialization or apply machine learning to real-world projects. 

  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.

• How is the new Machine Learning Specialization different from the original course?

  The new Machine Learning Specialization includes an expanded list of topics that focus on the most crucial machine learning concepts (such as decision trees) and tools (such as TensorFlow).

  In the decade since the first Machine Learning course debuted, Python has become the primary programming language for AI applications. The assignments and lectures in the new Specialization have been rebuilt to use Python rather than Octave, like in the original course. 

  Before the graded programming assignments, there are additional ungraded code notebooks with sample code and interactive graphs to help you visualize what an algorithm is doing and make it easier to complete programming exercises. 

  The section on practical advice on applying machine learning has been updated significantly based on emerging best practices from the last decade.
