Text to Audio Alignment
Šikula, Vojtěch ; Beneš, Karel (referee) ; Szőke, Igor (advisor)
This bachelors thesis is dealing with text to audio alignment. I present here works which are dealing with same problem. For evaluation have been used data from MGB Challenge 2015. Technique used here is using phoneme transcription and its alignment with transcript. Alignment was done with different models. The best results have been achieved by intersection of two alignments from models from good records.

Vliv genotypů pro gen leptin na vybrané kvalitní ukazatele hovězího masa
BENEŠ, Karel
The dissertation "The Influence of Genotype of Leptin Gene on Qualitative Characteristics of Beef" describes the effect of polymorphisms of gene of leptin on selected qualitative, morphometric and weight indicators of beef and carcass. The analysis was carried out on 333 bulls of Czech Fleckvieh, which were genotyped (by PCR/RFLP method) of chosen locus. This locus is associated with qualitative changes in beef according to previous foreign studies. The weight of carcass, fore and hind quarter of the right half of the carcass, the weight of the individual tissues (meat, bone, and fat) and the weight of main meaty parts from the right half of carcass were measured. Before the dissection chosen morphometric indicators were measured. After the dissection, a sample of the musculus longissimus lumborum et thoracis was taken and then analysed in the laboratory. Basic chemical composition (dry matter, fat content, protein, and ash), muscle fibers diameter and fatty acid profile was determined. In addition, pH, added water holding capacity, colour (CIE Lab colour coordinates) were analysed both for one-day post-mortem and after 14 days of ageing. The shear force (using the Warner-Bratzler probe) was evaluated at the same time intervals as for both raw and heat-treated samples by grilling. The studied LEP polymorphism had a statistically significant effect on the weight of the hot carcass, the weight of right half of carcass and fore and hind quarter. LEP polymorphism significantly affected the proportion of meat on the right half of carcass, the weight of the bones and total weight of the I. class meat, and the weight of the I. class meat in the fore quarter. Further, the effect of LEP polymorphism on the weight of boneless round, boneless chuck, plate, flank, rib, hind shank, and meat trimmings of fore quarter was found. In a group of morphometric indicators, the effect was significant on lengths of round, fullness of round and round circumference. In the case of chemical composition, the effect of LEP polymorphism on the intramuscular fat content was significant. From the qualitative indicators, the effect was significant on the pH value and added water holding capacity, both one-day post-mortem and after 14 days of ageing. In the case of tenderness, the effect on shear force of heat treated, non-aged meat was significant. From the indicators describing colour, a statistically significant effect on the indicator of lightness was found in the case of unconditioned meat and after 14 days of ageing the effect was significant on the indicator characterising yellow colour and the colour saturation. Determination of fatty acid profile was carried out by gas chromatography. The effects of studied polymorphism and differences between LEP genotypes were found in myristic, palmitic, palmitoleic, linoleic, -linolenic, -linolenic, conjugated linoleic, eisocapentaenoic, docosatetraenoic, docosapentaenoic both n-6 and n-3 and docosahexaenoic acids. From aggregated indicators, the statistical significant effect of LEP polymorphims on PUFA content, omega-3 fatty acids content, and omega-6/omega-3 fatty acids ratio was found. In connection with other candidate gene loci influencing the quality of beef, the results of dissertation can be used in the preparation of breeding schemes aimed at the production of quality breeding animals, highlighting the higher quality standards of the produced meat.

Artificial Poet
Bančák, Michal ; Szőke, Igor (referee) ; Beneš, Karel (advisor)
The paper presents a work on automatic poetry generation using the Long Short-TermMemory recurrent neural network. The aim of this work is to create an application thatimitates the writing of poems. This is a character-level language modeling in the Slovaklanguage. The neural network model used in the work consists of three layers of LSTM,with 400 hidden units. A collection of poems in the Slovak language with a size of 900k characters was also created for this work. . The final model is generating text that has poemelements. Achieved accuracy of generation is 41.85%.

Recurrent Neural Networks with Elastic Time Context in Language Modeling
Beneš, Karel ; Veselý, Karel (referee) ; Hannemann, Mirko (advisor)
Tato zpráva popisuje experimentální práci na statistické jazykovém modelování pomocí rekurentních neuronových sítí (RNN). Je zde předložen důkladný přehled dosud publikovaných prací, následovaný popisem algoritmů pro trénování příslušných modelů. Většina z popsaných technik byla implementována ve vlastním nástroji, založeném na knihovně Theano. Byla provedena rozsáhlá sada experimentů s modelem Jednoduché rekurentní sítě (SRN), která odhalila některé jejich dosud nepublikované vlastnosti. Při statické evaluaci modelu byly dosažené výsledky relativně cca. o 2.7 % horší, než nejlepší publikované výsledky. V případě dynamické evaluace však bylo dosaženo relativního zlepšení o 1 %. Dále bylo experimentováno i s modelem Strukturně omezené rekurentní sítě, ale ten se nepodařilo natrénovat k předpokládáným výkonům. Konečně bylo navrženo rozšíření SRN, pojmenované Náhodně prořidlá rekurentní neuronová síť. Experimentálně bylo potvrzeno, že RS-RNN dosahuje lepších výsledků v učení vlastního trénovacího korpusu a kombinace několika RS-RNN modelů přináší o 30 % větší zlepšení než kombinace stejného počtu SRN.

Finite State Grammars and Language Models for Automatic Speech Recognition
Beneš, Karel ; Glembek, Ondřej (referee) ; Hannemann, Mirko (advisor)
Tato práce se zabývá transformací bezkontextových gramatik na váhované konečně stavové převodníky. Je vybrána podmnožina bezkontextových gramatik, kterou lze tranformovat přesně. Je představen test, zda daná gramatika naleží do této podmnožiny, i algoritmus převodu. Dále je popsán vlastní nástroj, který tyto postupy implementuje, včetně způsobu zpracování vstupu a výstupu. S použitím toho nástroje byl vytvořen systém rozpoznání řeči pro kokpit letadla. Jsou představeny výsledky ukazující, že systém založený na takto získaném modelu jazyka podává výrazně lepší výkon, než je dosažen při použití obecného modelu.

Possibilites of improving the quality of beef by ageing
BENEŠ, Karel
Internal and external factors affect the quality of meat, however ageing affects final product. Main objective of this work was to determine the effects of ageing on selected physical factors (pH, colour, water holding capacity and texture shear force) which affect meat quality from consumer and further meat processing perspective. Measuring of those factors was performed in periodical time sequences (one day post-mortem and 14 days of ageing) and factors of raw and heat-modified meat were measured. There were two hundred and fifty-eight samples from Czech pied cattle used in research. Musculus longissimus lumborum et thoracis (sirloin) was analyzed. Statistically high shear force difference (P=0.001) was identified at heat-modified and aged samples (decrease from 22.574 kg to 14.885 kg). Decrease of shear force during ageing of raw meat samples was observed at normal pH (pH < 5.8) beef ? from 6.403 kg to 5.982 kg. Correlations between pH and water holding capacity was found at samples which undergone ageing (r = 0.879 ***) and also at one day post-mortem samples (r = 0.872 ***). Middle correlation was observed between colour and pH at all colour parameters ? L* (r = -0.479 ***), a* (r = -0.478 ***) and b* (r = -0.581 ***). Water holding capacity and pH have influence on shear force of raw beef and also heat-modified beef; this was confirmed by correlation analysis. Lightness (L*) and water holding capacity affect heat-modified samples texture which was confirmed with multi-regression linear analysis (R2 = 0.565). As shown above the influence of meat ageing on quality parameters is high and properly aged meat from young bulls has better texture values. If the aged beef will be sold regularly it could be expected that consumer demand will increase especially due to remove the inconsistency of the quality of beef.
