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 basic algorithms in this field. To get acquainted with the algorithmic description of the main language levels: morphology, syntax, semantics, and pragmatics, as well as the resources of natural language data - corpora. To conceive basics of knowledge representation, inference, and relations to the artificial intelligence.
