A language model is a set of restrictions on the sequence of words allowed in a given language, and these restrictions can be expressed, for example, by the rules of a generative grammar or by a statistic of each pair of words evaluated in a given language. simple educational building. 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.
语言模型是对给定语言中允许的单词序列的一组限制,这些限制可以表示,例如,通过生成语法的规则或通过给定语言中评估的每对单词的统计量。简单的教育建筑。虽然有些单词的音素发音相似,但人们通常并不难识别这些单词。它主要与了解上下文以及非常擅长其中可能出现的单词或短语有关。语言模型的目的是为语音识别系统提供上下文。语言模型确定系统语言中允许使用哪些单词,以及它们出现的顺序。语言模型被训练,即通过观察文本语料库中的单词序列来估计n-gram概率。减少混淆通常在包含数百万个单词标记的训练数据上执行。但是,正如已经观察到的那样,减少混淆并不能改善语音识别结果。因此,应该使用算法来改进语言模型对语音识别的影响,特别是在给定语音历史的情况下,确定说话人下一个说话词的概率分布的语言模型。近年来,许多语音识别系统都使用了为特定语言创建的语言模型。语言模型在语音识别中的应用有助于提高语音识别的效率。许多研究人员已经为乌兹别克语开发了一个传统的语言模型[8]-[12],但是这个模型并没有给出预期的结果。这就需要为乌兹别克语建立其他模型。本文提供了有关自然语言、构建自然语言模型以及将其应用于语音识别的信息。讨论了与自然语言模型构建相关的研究,统计模型构建中出现的问题,以及可用于解决这些问题的方法。

Option pricing is an important topic in the field of quantitative finance. 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.
期权定价是定量金融领域的一个重要课题。传统的Black-Scholes模型公式需要大量的假设,而这些假设在实际中往往不存在,基于统计的回归分析和时间序列方法对非平稳数据的拟合能力较差。深度学习在识别数据的结构和模式方面优于传统的计量经济模型,并且可以有效地学习时间序列的非线性和非平稳特征,更适合期权定价问题的研究。Transformer模型在处理时间序列数据方面比传统的递归神经网络模型具有更大的优势,主要体现在性能和速度方面。在这项工作中,我们将比较不同的模型,得到预测能力最强的深度学习模型。通过对中国市场50只ETF期权和股票的数据进行实证分析,证明了Transformer模型在时间序列预测方面优于传统深度学习模型。

Polymer optical fibers have great significance due to a wide range of applications, such as data transmission, sensing, and illumination. In this study, we proposed a novel hollow-core polymer optical fiber fabricated by a commercially available 3D printer with guiding properties in the near-infrared region. The fiber was drawn conventionally using a thermal drawing tower from a 3D printed preform. Light guidance by inhibited coupling through the air core surrounded with six-pointed star cladding tubes was demonstrated. Two significant transmission bands with low losses of 0.325 dB/cm at 1300 nm and 0.38 dB/cm at 1530 nm were detected.

Cotton production is considered crucial in various parts of the world and determining the diseases well in advance is a vital factor that directly has an effect on the yield. To tackle this issue, a CNN - based approach has been proposed which can detect a diseased plant and the leaf. For detection, the VGG19 artificial neural network has been trained by using google collaboratory. Moreover, unsupervised learning was used with Kaggle cotton plant dataset for training the model followed by validation and testing. Once the training is done, the saved model can easily predict whether the plant or leaf is diseased or not.

It is known that the study and research of existing problems of medicine using modern information technologies is the most relevant today. Mathematical modeling of the activities of the regulatory mechanisms of living systems at the organismal, organ, cellular and molecular-genetic levels is one of the promising areas in the field of medical biology. 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. The results of a qualitative study of the equations of hepatitis B regulators in the quasi-stationary state of liver cells are presented.

The problem of forming a latent feature space through nonlinear transformations of different type features is considered. Two types of transformations are used: the replacement of gradations of nominal features by the values of the function of objects belonging to classes and the combination of features according to the rules of hierarchical agglomerative grouping. The dimension of the new latent space is less than the original one and it is determined by the grouping algorithm. The ordering of latent features in relation to informativeness allows solving the problem of the curse of dimensionality and visualizing data taking into account the description of class objects.A comparative analysis of linear and nonlinear methods for reducing the dimension of space is given. The division of methods using the division of objects into classes and without such division is given. Without division into classes, the PCA and T-SNE methods are implemented on data in interval measurement scales.Using the method of calculating generalized estimates of the objects it is doing their visualization according to a certain set of different type features.

The paper considers the issues of optimizing the modes of electric power systems based on the methods of intelligent technologies: evolutionary and ant algorithms, taking into account the features of the object under consideration. 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. When solving the problem of optimal placement and determination of the parameters of compensating devices and linear regulators, it was possible to reduce losses in the system by 3.5%.
本文考虑了基于智能技术方法的电力系统模式优化问题:进化算法和蚁群算法,并考虑了被考虑对象的特征。提出了以电力设施燃料总成本最小为目标的优化准则。确定了技术单位的功能动态及其操作模式所施加的主要限制。这些限制以表征机组稳定状态的线性方程组的形式以及以不等式的形式呈现,这些不等式是对发电参数的限制性限制。为了解决这个问题,进化建模算法和蚁群算法被开发出来。对这些算法进行了比较分析,以确定它们的能力和适用范围。在具有离散变量值的问题中使用进化算法不需要对问题进行任何假设和简化。在解决补偿装置和线性调节器的最佳放置和参数确定问题时,有可能将系统的损耗降低3.5%。

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.

In the article a mathematical model based on the Hamilton-Ostrogradsky variational principle is presented. Using the Kirkhgoff-Lyav hypothesis, the mathematical model in three-dimensional form is transformed into a two-dimensional model. The variational representation of potential and kinetic energy as well as the variation of work done by external forces, Cauchy relations, Hooke’s law, and Lorentz force and Maxwell’s electromagnetic forces are determined using the tensor view. In this case, the effects of the electromagnetic field on the deformation stress state of the magnetoelastic plate are considered. The result was a mathematical model in the form of a system of high-order differential equations with special derivatives with initial and boundary conditions relative to the displacement. To solve the problem, a computational algorithm was developed, for which a practical software tool was created, computational experiments were conducted, and the results obtained were analyzed.
文章介绍了一个基于汉密尔顿-奥斯特洛夫斯基变分原理的数学模型。利用 Kirkhgoff-Lyav 假设,将三维形式的数学模型转化为二维模型。利用张量视图确定了势能和动能的变分表示以及外力做功的变化、柯西关系、胡克定律、洛伦兹力和麦克斯韦电磁力。在这种情况下,考虑了电磁场对磁弹性板变形应力状态的影响。其结果是建立了一个数学模型,其形式为带有特殊导数的高阶微分方程系统,并带有与位移相关的初始条件和边界条件。为了解决这个问题,开发了一种计算算法,并为此创建了一个实用的软件工具,进行了计算实验,并对所得结果进行了分析。
