### Machine Learning

#### Course Description

#### General Competencies

Familiarity with supervised and unsupervised machine learning methods, classification and regression tasks. Understanding of generative, discriminative, parametric, and nonparametric models. Understanding of theoretical foundations of these models, the underlying assumptions, and their advantages and disadvantages. Capability to design and implement a machine learning system for classification, regression, or clustering and to evaluate its performance.

#### Learning Outcomes

- define the basic concepts of machine learning
- distinguish between generative and discriminative, parametric and nonparametric and probabilistic and nonprobabilistic models models
- explain the theoretical assumptions, advantages, and disadvantages of basic machine learning algorithms
- apply model selection and statistical evaluation of the learned model
- apply various classification algorithms, inclusive generative, discriminative, and nonparametric ones
- apply clustering algorithms and cluster validation
- design and implement a machine learning method for classification/clustering and carry out its evalution
- assess the suitability of a machine learning algorithm for a given task

#### Forms of Teaching
