Domain Specific Data Crawling for Language Model Adaptation
Gregušová, Sabína ; Švec, Ján (referee) ; Karafiát, Martin (advisor)
The goal of this thesis is to implement a system for automatic language model adaptation for Phonexia ASR system. System expects input in the form of source that, which is analysed and appropriate terms for web search are chosen. Every web search results in a set of documents that undergo cleaning and filtering procedures. The resulting web corpora is mixed with Phonexia model and evaluated. In order to estimate the most optimal parameters, I conducted 3 sets of experiments for Hindi, Czech and Mandarin. The results of the experiments were very favourable and the implemented system managed to decrease perplexity and Word Error Rate in most cases.
Binding of azaphthalocyanine on 5'-end of oligonucleotide - "click" chemistry
Křížová, Iveta ; Kopecký, Kamil (advisor) ; Švec, Jan (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Chemistry and Drug Control Student: Iveta Křížová Supervisor: PharmDr. Kamil Kopecký, Ph.D. Title of diploma thesis: Binding of azaphthalocyanine on 5'-end of oligonucleotide - "click" chemistry This diploma thesis is focused on synthesis of pyrazin-2,3-dicarbonitrile derivates that are substituted with alkylamine substituents in location 5 and 6. Then cyclotetramerization of these compounds to the final azaphthalocyanines was realized. Alkylamine substituents were chosen in the way, that bond on 5'-end of oligonucleotide with terminal alkyn modification could be performed according to Huisgen 1,3-dipolar cycloaddition. Azaphtalocyanine with one hydoxyl group was prepared and described. Preparation of intended structure with one azide group was unsuccessful. Azaphtalocyanines are characterized by important photophysical and photochemical properties. Therefor were these compounds characterized with NMR, IR and mass spectra. In section Theory was explained the principle of quenching of fluorescence, practical use of quenching and overview of up to date the most commonly used quencher of fluorescence. There is also comparing of their positive and negative properties and little bit outlining of properties...
Personal Voice Activity Detection
Sedláček, Šimon ; Landini, Federico Nicolás (referee) ; Švec, Ján (advisor)
Cílem této práce je implementovat, otestovat a vyhodnotit řečníkem podmíněnou metodu pro detekci hlasu ( Voice Activity Detection , VAD) nazvanou Personal VAD. Pro detekci využívá tato metoda LSTM neuronových sítí a jejím účelem je vytvoření systému schopného spolehlivě detekovat řečové signály cílového řečníka při zachování vlastností typického VAD systému co se velikosti modelu, odezvy a nízkých nároků na zdroje týče. Systém je trénován pro klasifikaci řečových rámců do tří tříd: neřeč, řeč necílového a řeč cílového řečníka. Za tímto účelem využívá metoda speaker embedding vektory pro reprezentaci cílového řečníka jako součást vstupních příznaků. Některé z náročnějších variant systému využívají skórování rámců systémem pro verifikaci řečníka, což vede ke zvýšení spolehlivosti klasifikace. Vedle základní metody skórování představené v originálním článku byly navrženy dvě modifikace, jež základní metodu překonaly a zlepšily spolehlivost výsledného systému i v akusticky náročných prostředích.
The Effect of Bulkiness of Non-peripheral Substituents of Phthalocyanines on their Absorption and Photophysical properties
Paušímová, Zuzana ; Nováková, Veronika (advisor) ; Švec, Jan (referee)
Charles University in Prague, Faculty of Pharmacy in Hradec Králové Department Department od Biophysics and Physical Chemistry Student Zuzana Paušímová Supervisor doc. PharmDr. Veronika Nováková Ph.D. Title of thesis The Effect of Bulkiness of Non-peripheral Substituents of Phthalocyanines on their Absorption and Photophysical Properties Phthalocyanines are planar macrocyclic compounds which absorb the light over 670 nm due to their large system of conjugated double bounds. Peripheral substitution of phthalocyanines significantly affects the position of the main absorption band. Absorption at longer wavelengths is highly advantageous in any biological applications because such light does not interfere with endogenous chromophores. It was discovered that the desired red-shift of absorption band is much more pronounced at non-peripherally substituted phthalocyanines. However, it was recently found out that the presence of bulky non-peripheral substituent shifts significantly absorption maximum back to lower wavelengths. The aim of this study was to explain this phenomenon more in detail. For this purpose, a series of phthalocyanines bearing non-peripheral (alkyl- or arylsulphanyl) substituents of different bulkiness was prepared. Syntheses included nucleophilic substitution leading to appropriate...
Recognition of Multi-Talker Overlapping Speech Using Neural Networks
Hradil, Jaromír ; Švec, Ján (referee) ; Žmolíková, Kateřina (advisor)
Tato práce se zabývá rozpoznáváním řeči překrývajících se řečníků pomocí neuronové sítě. Zkoumá  problém rozpoznávání řečí od vícero řečníků a způsoby, jimiž se tento daný problém řeší. Jedná se konkrétně o aplikaci kromě tradičních komponentů jako konvoluční neuronové sítě, LSTM atd. také speciálních komponentů: attention mechanismus a gated konvoluce. A dále také aplikace techniky zvanou permutation invariant training. Součástí této práce je aplikování těchto přístupů na přidělená trénovací data, která jsou tvořena uměle vytvořenými směsmi dvou řečníků předčítající články z Wall Street Journal. Dalším krokem bylo natrénování příslušných architektur používající kombinující prvky zmíněné nahoře. Modely v této práci nahrazují akustický model. Jednalo se o dvě architektury užívající různé typy attention mechanismu a o jednu bez něj.  Experimenty ukázaly, že architektury užívající attention mechanismus v tomto typu úlohy něpřekonaly tradičnější architekturu s užitím gated konvolucí. Přesto ale ukázaly potenciál.

Security Integration Processes in the Post-Soviet Space
Švec, Jan ; Rolenc, Jan Martin (advisor) ; Cibulková, Petra (referee)
The thesis deals with the topic of security integration processes in the post-Soviet space, and focuses on the Collective Security Treaty Organization (CSTO). The aim of the thesis is to specify the character of the CSTO from the perspective of collective security theories. The first part of the thesis studies different approaches to the concept of collective security. The result of the first part is the specification of criterions, which allow to identify collective security organization. The second part describes the characteristics of post-Soviet space and integration processes in the post-Soviet space. The third part analyses the Collective Security Treaty Organization. The conclusion provides arguments, why CSTO is not a collective security organization and why it should rather be considered as a collective defense organization.
