Although there are words with similar-sounding phonemes, it is usually not difficult for people to recognize the word. It mostly has to do with knowing the context and being very good at what words or phrases might be in it. The purpose of the language model is to provide context to the speech recognition system. The language model determines what words are allowed in the system language and in what order they can occur.Language models are trained, i.e., n-gram probabilities are estimated by observing sequences of words in a text corpus. Confusion reduction is typically performed on training data containing millions of word tokens. But, as has been observed, reducing confusion does not improve speech recognition results. Therefore, algorithms should be used that improve language models in terms of their impact on speech recognition, especially language models that determine the probability distribution of the speaker’s next spoken words given the speech history.In recent years, many speech recognition systems have been developed that use language models created for specific languages. And the use of language models in speech recognition serves to increase the efficiency of speech recognition. Many researchers have developed a traditional language model for the Uzbek language [8] –[12], but this model does not give the expected results. This requires the construction of other models for the Uzbek language. This article provides information about natural language, building natural language models, and applying them to speech recognition. Discusses research related to the construction of natural language models, problems that arise in the construction of statistical models, and approaches that can be used to solve them.","PeriodicalId":332984,"journal":{"name":"2022 International Conference on Information Science and Communications Technologies (ICISCT)","volume":"513 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123072680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The traditional Black-Scholes model formulation requires a large number of assumptions, which often does not exist in practice, and the statistically-based regression analysis and time series methods have poor fitting ability for non-stationary data. Deep learning has advantages over traditional econometric models in identifying the structure and patterns of data, and can effectively learn the nonlinear and non-stationary characteristics of time series, which is more suitable for the study of option pricing problems. The Transformer model has greater advantages over the traditional recurrent neural network model in the processing of time series data, mainly in terms of performance and speed. In this work, we will compare different models and get the deep learning model with the strongest prediction ability. Based on the collected data related to 50 ETF options and stocks in the Chinese market for empirical analysis, it is demonstrated that the Transformer model outperforms the traditional deep learning model in time series prediction.","PeriodicalId":332984,"journal":{"name":"2022 International Conference on Information Science and Communications Technologies (ICISCT)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125111976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The scientific research discusses the results of a quantitative study of the regulatory mechanisms of liver cells and hepatitis B viruses based on mathematical and computer models by using the Matlab application package. The study of the quasi-stationary state of the liver cell under the pressure of hepatitis B viruses using mathematical modeling methods is one of the urgent tasks. The use of mathematical modeling to analyze the interaction of the regulatory mechanisms of molecular genetic systems of liver cells and hepatitis B viruses makes it possible to analyze the main forms of infectious viral hepatitis B in a quasi-stationary state of liver cells.

An optimization criterion has been formulated, which includes minimizing the total cost of fuel in electric power facilities. The main restrictions imposed by the dynamics of the functioning of technological units and their mode of operation are determined. These restrictions are presented in the form of a system of linear equations that characterize the steady state of the units, as well as in the form of inequalities, which are the limiting restrictions on the parameters of the generated electricity. To solve this problem, evolutionary modeling algorithms and an ant colony algorithm have been developed. A comparative analysis of these algorithms was carried out in order to determine their capabilities and scope. The use of evolutionary algorithms in problems with discrete values of variables does not require any assumptions and simplifications of the problem.
