Course 1: Supervised Machine Learning: Regression and Classification
This introductory course sets the stage for understanding supervised machine learning, focusing on key algorithms used for regression and classification tasks.
-
Week 1 covers the basics of regression and the difference between supervised and unsupervised learning. Learners are introduced to training models using gradient descent. Optional labs provide hands-on experience with model representation, cost function, and gradient descent.
-
Week 2 delves into practical aspects of gradient descent, multiple linear regression, and introduces optional labs on Numpy vectorization, feature scaling, feature engineering, and more.
-
Week 3 focuses on logistic regression, a fundamental classification algorithm. Students explore cost functions, gradient descent in logistic regression, and tackle programming assignments in logistic regression.
Course 2: Advanced Learning Algorithms
This course takes learners deeper into more complex machine learning models and techniques.
-
Week 1 introduces neural networks, giving learners an understanding of how these powerful models work. The course guides participants through neural networks implementation using popular libraries like TensorFlow and also covers numpy-based approaches.
-
Week 2 explores the training of neural networks, activation functions, and multiclass classification. Through optional labs, students get practical experience with concepts like RELU, softmax, and multiclass classification.
-
Week 3 shifts focus to practical advice for applying machine learning, discussing bias and variance, and the overall machine learning development process.
-
Week 4 wraps up with decision trees, discussing both their theoretical underpinnings and practical applications. Learners explore decision tree ensembles and their learning processes through quizzes and programming assignments.
