Subject specific learning outcomes and competences

The students will get acquainted with natural language processing and will understand a range of neural network models that are commonly applied in the field. They will also grasp basics of neural implementations of attention mechanisms and sequence embedding models and how these modular components can be combined to build state of the art NLP systems. They will be able to implement and to evaluate common neural network models for various NLP applications.
Students will improve their programming skills and their knowledge and practical experience with tools for deep learning as well as with general processing of textual data.

Learning objectives

To understand natural language processing and to learn how to apply modern machine learning methods in this field. To get acquainted with advanced deep learning architectures that proved to be successful in various NLP tasks. To

understand the use of neural networks for sequential language modelling, to understand  their use as conditional language models for transduction tasks, and to approaches employing these techniques in combination with other mechanisms for advanced applications.

Why is the course taught

More and more people use natural language processing (NLP) in their everyday life - machine translators, virtual assistants, etc. Most NLP tasks have been recently realised by means of deep neural networks. Students of this course will learn, how the computer translates texts between languages, how it recognizes what a review author likes or dislikes about a new product, and how virtual asistants can answer questions on the Wikipedia text.

Prerequisite knowledge and skills

Good knowledge of artificial neural network models and Python programming.
