This course covers practical algorithms for supervised machine learning from a variety of perspectives. Topics include generative/discriminative learning, parametric/non-parametric learning, deep neural networks, support vector machines, decision trees as well as learning theory. The course will also discuss recent applications of machine learning, such as computer vision, data mining, natural language processing, speech recognition and robotics.

1. Linear regression, Overfitting, Regularization, Sparsity

2. Maximum likelihood estimation

3. Logistic regression

4. Naive Bayes

5. Perceptron

6. Convex optimization, SGD

7. SVM and kernels

8. Neural networks and deep learning: DNNs, CNNs

9. Decision trees

Homeworks are due at the beginning of the class on the specified dates. No late homeworks or projects will be accepted.

• Homeworks: 4 HWs (40%)

• Project (20%)

• Two Midterm Exams (40%)

Homework consist of both analytical questions and programming assignments. Programming assignments must be done via Python. Both codes and results of running codes on data must be submitted.

The exam consist of analytical questions from topics covered in the class. Students are allowed to bring a single cheat sheet to the exam.
