Learning outcomes of the course unit

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.

Aims

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.

Specification of controlled education, way of implementation and compensation for absences

The evaluation includes mid-term test, individual project, and the final exam. The mid-term test does not have a correction option, the final exam has two possible correction runs.
