=== What is the main purpose of this course? ===
 
There is a growing business need of individuals skilled in artificial intelligence, data analytics, and machine learning. Therefore, the purpose of this course is to provide students with an intensive treatment of a cross-section of the key elements of machine learning, with an emphasis on implementing them in modern programming environments, and using them to solve real-world data science problems.

  +
=== ILOs defined at three levels ===
== Prerequisites ==
 
 
The course will benefit if students already know some topics of mathematics and programming.
 
* Programming: Python, numpy, basic object-oriented concepts, memory management, data structures, and algorithms.
 
* Maths: A thorough understanding of mathematics (linear algebra, calculus, probability theory and statistics) is necessary to gain a solid understanding of the internal working of machine learning algorithms. For a more concrete identification of subtopics, please see chapters 2, 3 and 4 of [1], which has done an excellent job in listing and describing all important maths subtopics essential for machine learning students. In addition to that, students are strongly advised to gain a basic understanding of descriptive statistics and data distributions, statistical hypothesis testing, and data sampling, resampling, and experimental design techniques
