Smart weather forecast
Cigáň, Juraj ; Marada, Tomáš (referee) ; Zuth, Daniel (advisor)
This bachelor thesis focuses on the creation of an algorithm of automatically generated texts and their particular application in computer weather forecasts. It is aimed at gathering information from the fields mentioned above as well as about in the sphere of the software used to reach the set goals. The first part regards the history of development of digital generating and its present-day use. It specifies main rules and methods necessary to design such a programme. It also deals with the accumulation of required information for the designing of its own meteorological station and describes important features of the software, which can be used in such a process. Lastly, it also describes the creation of a programme which is able to gain and process information about weather forecasts and subsequently share them on social platform Twitter, all in consideration with the researches in previous chapters.

Neural Network for Autocomplete in the Browser
Kubík, Ján Jakub ; Zemčík, Pavel (referee) ; Kolář, Martin (advisor)
The goal of this thesis is to create and train a neural network and use it in a web browser for English text sequence prediction during writing of text by the user. The intention is to simplify the writing of frequent phrases. The problem is solved by employing a recurrent neural network that is able to predict output text based on the text input. Trained neural network is then used in a Google Chrome extension. By normalized ouput of the neural network, text choosing by sampling decoding algorithm and connecting, the extension is able to generate English word sequences, which are shown to the user as suggested text. The neural network is optimized by selecting the right loss function, and a suitable number of recurrent layers, neurons in the layers, and training epochs. The thesis contributes to enhancing the everyday user experience of writing on the Internet by using a neural network for English word sequence autocomplete in the browser.

Stylized Natural Language Generation in Dialogue Systems
Bolshakova, Ksenia ; Kesiraju, Santosh (referee) ; Fajčík, Martin (advisor)
Tato práce se zabývá přístupy generování přirozeného jazyka v různých stylech. Kromě toho také zkoumá schopnost modelů řídit sílu projevu stylu v generované sekvenci. Model pro generování přirozeného jazyka byl implementován s několika aspekty projevů stylu, konkrétně poezie, humor, sentiment a specifičnost. Jako strategie dekódování jazykových modelů byly použity Beam search a Nucleus sampling. Navrhované experimenty jsou založeny na váženém dekódování. Zejména pravděpodobnostní funkce vypočítaná pomocí jazykového modelu, který generuje odpověď, je modifikována dvěma přístupy. První přístup používá ručně vytvořené příznaky, například NIDF. Druhý používá neurální pravděpodobnostní jazykové modely natrénované na stylistických datových sadách. Architektura modelu je prezentována ve dvou verzích. První variantou je model založený na LSTM a druhá varianta využívá nejmodernější předpřipravené modely BART a GPT-2 pro generování textu. Experimenty odhalily problém, že i současné nejmodernější modely trpí špatným odhadem kompromisu mezi stylem a kontextem. Jinými slovy, čím více se styl projeví v generované sekvenci, tím méně se vztahuje k tématu diskutovanému v dialogu.

Novel Methods for Natural Language Generation in Spoken Dialogue Systems
Dušek, Ondřej ; Jurčíček, Filip (advisor) ; Ircing, Pavel (referee) ; Žabokrtský, Zdeněk (referee)
Title: Novel Methods for Natural Language Generation in Spoken Dialogue Systems Author: Ondřej Dušek Department: Institute of Formal and Applied Linguistics Supervisor: Ing. Mgr. Filip Jurčíček, Ph.D., Institute of Formal and Applied Linguistics Abstract: This thesis explores novel approaches to natural language generation (NLG) in spoken dialogue systems (i.e., generating system responses to be presented the user), aiming at simplifying adaptivity of NLG in three respects: domain portability, language portability, and user-adaptive outputs. Our generators improve over state-of-the-art in all of them: First, our gen- erators, which are based on statistical methods (A* search with perceptron ranking and sequence-to-sequence recurrent neural network architectures), can be trained on data without fine-grained semantic alignments, thus simplifying the process of retraining the generator for a new domain in comparison to previous approaches. Second, we enhance the neural-network-based gener- ator so that it takes preceding dialogue context into account (i.e., user's way of speaking), thus producing user-adaptive outputs. Third, we evaluate sev- eral extensions to the neural-network-based generator designed for producing output in morphologically rich languages, showing improvements in Czech generation. In...

Generator of computer descriptions
Matějka, Jan ; Rosa, Rudolf (advisor) ; Dušek, Ondřej (referee)
This thesis deals with the problem of generating coherent and well-formed sentences from structured data. The goal of the thesis is to create a tool which could make generating brief descriptions of electronics based on parameters in the form of structured data easier. The tool can be useful for e.g. e-shops with such electronics. The first part of the thesis introduces possible solutions to this problem. The thesis next describes data needed for solving the problem, including the ways of acquiring such data and structure of the data. Two selected solutions are then described including their implementation. The thesis then examines the advantages and disadvantages of the selected solutions and evaluates texts generated by the created tool.
