Spoken Language Translation via Phoneme Representation of the Source Language
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2020)Datum obhajoby: 8. 7. 2020We refactor the traditional two-step approach of automatic speech recognition for spoken language translation. Instead of conventional graphemes, we use phonemes as an intermediate speech representation. Starting with the ... -
An implicit representation of sets
Výsledek obhajoby: OBHÁJENO(Univerzita Karlova, Matematicko-fyzikální fakulta, 2020)Datum obhajoby: 8. 7. 2020In our bachelor thesis, we described an implicit data structure that, given a way to maintain an implicit representation of polylogarithmic buckets, could implement all the dynamic ordered dictionary operations in logarithmic ... -
