Machine learning is the scientific field that provides computers the ability to learn without being explicitly programmed (definition by Wikipedia). Machine learning lies at the heart of many realworld applications, including recommender systems, web search, computer vision, autonomous cars and automatic language translation.
The course will provide an overview of fundamental topics as well as important trends in machine learning, including algorithms for supervised and unsupervised learning, dimensionality reduction methods and their applications. A substantial lab section will involve group projects on a data science competition and will provide the students the ability to apply the course theory to realworld problems.

Course Structure and Objectives
Structure
Each section of the course is divided into 1h30' lecture and 1h30' lab. The labs will include handson assignments (using Python) and will provide the students the opportunity to deal with ML tasks in practice.
Learning objectives
The course aims to introduce students to the field of machine learning by:
 Covering a wide range of topics, methodologies and related applications.
 Giving the students the opportunity to obtain handson experience on dealing with realworld problems.
We expect that by the end of the course, the students will be able to:
 Identify problems that can be solved using machine learning methodologies.
 Given a problem, identify and apply the most appropriate algorithm(s).
 Implement some of those algorithms from scratch.
 Evaluate and compare machine learning algorithms for a
particular task.
 Deal with realworld data challenges.
Prerequisites
There is no official prerequisite for this course. However, the students are expected to:
 Have basic knowledge of probability theory and linear algebra.
 Be familiar with at least one programming language (e.g., Python or any language of their preference).
Reading material
There is no single required textbook for the course. We will recommend specific chapters from the following books:
 Shai ShalevShwartz and Shai BenDavid. Understanding Machine Learning: From Theory to Algorithms. Cambridge University Press, 2014.
 Christopher M. Bishop. Pattern Recognition and Machine Learning. Springer, 2011.
 Trevor Hastie, Robert Tibshirani, and Jerome Friedman. The Elements of Statistical Learning: Data Mining, Inference, and Prediction. Second Edition, Springer, 2017.
 Jure Leskovec, Anand Rajaraman, and Jeff Ullman. Mining of Massive Datasets. Cambridge University Press, 2014.
Evaluation
The evaluation of the course will be based on the following:
 Two assignments: the assignments will include theoretical questions as well handson practical questions and will familiarize the students with basic machine learning tasks.
 Project: The students are expected to form groups of 34 people, propose a topic for their project, and submit a final project report (it would also be interesting to organize a poster session at the end of the quarter). Please, read the project section for more details.
The grading will be as follows:
Assignment 1 (individual):  15% 
Assignment 2 (groups of 34 students):  35% 
Project (groups of 34 students):  50% 
Academic integrity
All of your work must be your own. Don't copy another student's assignment, in part or in total, and submit it as your own work. Acknowledge and cite source material in your papers or assignments.
Project
Details about the project of the course will be posted soon on piazza.
