Neural machine translation recently became a new interesting and successful paradigm. The new paradigm brings new theoretical concepts and new ways of seeing the classic problems of machine translation. The goal of this seminar is to familiarize the students with the theoretical framework of neural machine translation in such depth that would allow them to study the most recent academic papers on this topic.
Aim of the course - Czech
Last update: T_UFAL (09.01.2017)

Na prvních šesti seminářích se studenti formou přednášky a diskuse seznámí s následujícími tématy:

Rekurentní neuronové sítě a s nimi spojená matematická intuice

Sequence-to-sequence learning

Attention model a jeho varianty

Řešení problému omezeného slovníku

Pokročilé metody trénování (minimum risk training, zpětnovazební učení)

Ve zbývající části semestru budou formou studentských referátů prezentovány předem vybrané články z odborných konferencí a časopisů. V následující moderované diskuzi se studenti pokusí navrhnout, jak by bylo možné obsah probíraného článku naprogramovat.

Zápočet bude možné získat za:

Včasné písemné zodpovězení otázek k prezentovaným článkům a

Přednesení referátu k vybranému článku nebo fungující implementaci některého ze článků

Last update: doc. RNDr. Vladislav Kuboň, Ph.D. (05.06.2018)

Students pass the practicals by submitting sufficient number of assignments. The assignments are announced regularly the whole semester and are due in several weeks. Considering the rules for completing the practicals, it is not possible to retry passing it. Passing the practicals is not a requirement for going to the exam.

The exam consists of a written part and an optional oral part, where the students can react to queries regarding the written part and also answers additional questions.

The requirements of the exam correspond to the course syllabus, in the level of detail which was presented on the lectures.
