Machine Learning I

An introductory course to machine learning, with a focus on supervised learning using linear models. The course will have four parts: (1) mathematical background on linear algebra, probability, and optimization. (2) classification methods including Bayesian decision, linear regression, logistic, regression, and support vector machine. (3) robustness of classifier and adversarial examples. (4) learning theory on the feasibility of learning, VC dimension, complexity analysis, bias-variance analysis. Suitable for senior undergraduates and graduates with a background in probability, linear algebra, and programming.

Credit Hours:

3

Learning Objective:

  • Apply basic linear algebra, probability, and optimization tools to solve machine learning problems
  • Understand the principles of supervised learning methodologies, and can comment on their advantages and limitations
  • Explain the trade-offs in model complexity, sample complexity, bias, variance, and generalization error in the learning theory
  • Implement, debug, and execute basic machine learning algorithms on computers 

Description:

Machine Learning is a dual-level (500-level) course customized for science and engineering students who are seeking to develop a solid mathematical foundation of the subject. The course focuses on the fundamental principles of machine learning instead of a scattered set of algorithmic tools. Students completing the course will be able to formulate the practical machine learning problems into mathematical frameworks, implementing algorithms to execute the statistical inference tasks, and analyzing the performance and limitations of the algorithms. The course emphasizes the co-development of theory and programming. Students will have a hands-on experience implementing machine learning algorithms in Python.

Topics Covered:

  1. Linear regression, which covers regression models, outliers, ridge regularization, LASSO regularization, convex optimization, gradient descent algorithms, and stochastic algorithms
  2. Classification, which covers separability, Bayesian classifiers, ROC curves, precision-recall curves, logistic regression, and kernel methods
  3. Learning theory, which covers probability inequality, the probably approximately accurate framework, generalization bound, model complexity, sample complexity, VC dimension, bias, variance, overfitting, and validation
  4. Advanced topics of the state-of-the-arts, for example deep neural networks, generative models, and adversarial robustness
