Although numerical simulators can provide accurate predictions of numerous parameters in UGS reservoirs, in many cases this process can be computationally expensive. In particular, calculation time is one of the major constraints affecting decisions related to optimal well control and distribution of gas injection or withdrawal over the reservoir area. Novel deep learning methods that can provide a faster alternative to traditional numerical reservoir simulators with acceptable loss of accuracy are investigated in this paper. Hydrodynamic processes of gas flow in UGS reservoirs are described by partial differential equations (PDEs). Since PDEs involve approximating solutions in infinite-dimensional function spaces, this distinguishes such problems from traditional ones. Currently, one of the most promising machine learning approaches in scientific computing (scientific machine learning) is the training of neural operators that represent mappings between function spaces. In this paper, a deep learning method for hydrodynamic modeling of UGS is proposed. A modified Fourier neural operator for hydrodynamic modeling of UGS is developed, in which the model parameters in the spectral domain are represented as factorized low-rank tensors. We trained the model on data obtained from a numerical model of UGS with nonuniform discretization grid, more than 100 wells and complex geometry. Our method demonstrates superior performance compared to the original Fourier neural operator (FNO), with an order of magnitude (50 times) fewer parameters. Tensor decomposition not only greatly reduced the number of parameters, but also increased the generalization ability of the model. Developed neural operator simulates a given scenario in a fraction of a second, which is at least <span>(10^{6})</span> times faster than a traditional numerical solver.</p>","PeriodicalId":711,"journal":{"name":"Moscow University Physics Bulletin","volume":"79 2 supplement","pages":"S922 - S934"},"PeriodicalIF":0.4,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668043","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, machine learning-based solutions are increasingly being used to solve classification problems. However, these classifiers require proper training data sets to work correctly. The problem with training neural networks on real IACT data is that these data need to be prelabeled, whereas such labeling is difficult and its results are estimates. In addition, the distribution of incoming events is highly imbalanced. Firstly, there is an imbalance in the types of events, since the number of detected gamma quanta is significantly less than the number of protons. Secondly, the energy distribution of particles of the same type is also imbalanced, since high-energy particles are extremely rare. This imbalance results in poorly trained classifiers that, once trained, do not handle rare events correctly. Using only conventional Monte Carlo event simulation methods to solve this problem is possible, but extremely resource-intensive and time-consuming. To address this issue, we propose to perform data augmentation with artificially generated events of the desired type and energy using conditional generative adversarial networks (cGANs), distinguishing classes by energy values. In the paper, we describe a simple algorithm for generating balanced data sets using cGANs. Thus, the proposed neural network model produces both imbalanced data sets for physical analysis as well as balanced data sets suitable for training other neural networks.</p>","PeriodicalId":711,"journal":{"name":"Moscow University Physics Bulletin","volume":"79 2 supplement","pages":"S598 - S607"},"PeriodicalIF":0.4,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It consists in determining concentrations of the ingredient ions of multicomponent water solutions by their spectra. The problem of describing the spectra of multicomponent solutions is nonlinear and has no adequate mathematical model. Because of this, machine learning methods using experimental data were chosen to solve this problem. At the same time, inverse problems of spectroscopy are characterized by high input dimensionality with a large number of features, more or less relevant. In their turn, some of the relevant features are redundant due to their multicollinearity. This is caused by the fact that the characteristic lines have a width of several spectrum channels. Presence of redundant features leads to a deterioration in the quality of machine learning solution of the problem. Thus, there is a need for a feature selection procedure that takes into account both their relevance and redundancy, as well as their nonlinear relationship with the determined parameters. In this study, we considered a feature selection procedure based on the iterative selection of features with the highest relevance to the target variable and on the elimination of features with a high relationship with each other. In this selection process, we used a trained neural network to analyze weights and determine feature importance in a nonlinear way. We also used the Pearson correlation coefficient to measure how features are related to one another. Finally, we compared the quality of a neural network solution using spectroscopic data of the full set of input features and of its subsets.

A BCI is a system that records brain activity signals using electrophysiological methods and then processes these signals to generate control commands. The most challenging aspect of BCIs is the nonstationary nature of brain signals, which makes it difficult to achieve stable and accurate decoding. Therefore, developing robust methods for processing and classifying EEG signals to extract control commands is a critical research area. A related challenge is the low signal-to-noise ratio in EEG data, especially when target patterns are weak or the data is labeled inaccurately. This paper presents the results of an evaluation of an approach combining feature extraction and data augmentation techniques to address the aforementioned challenges applied to the classification of premotor potentials. The approach is based on the application of linear discriminant analysis (LDA) to sequentially extract informative components in the frequency and time domains For the first time, the applicability of this algorithm to EEG containing premotor patterns of real movements is demonstrated. Features of different nature (spectral power, Hjorth parameters, interchannel correlations) were tested and compared with each other and a traditional approach based on common spatial patterns and a linear classifier. It is shown that transformations in the frequency domain alone improve accuracy from 63.9<span>(%)</span> in the traditional approach to 77.5<span>(%)</span> on a dataset of 16 experiments on different subjects. With additional transformation in the time domain, accuracy increases to 98.8<span>(%)</span>. On average, across different model configurations, a segment length of 500 ms is the most optimal. Two approaches were developed and tested to achieve algorithm universality across subjects: universal transformations in frequency domain trained on data from all subjects and without this step at all. It is shown that accuracies of up to 98.3<span>(%)</span> can be achieved with such approaches. A discussion of optimal frequency bands, segment lengths, and features is provided. Thus, data from different subjects can be effectively classified by a common model, which is rare in global research and is usually accompanied by a number of assumptions, cumbersome models, and inferior accuracy. Thus, in addition to the achieved accuracy enhancement, the proposed algorithm exhibits robustness to transient noise and artifacts through signal segmentation into short epochs. It also effectively addresses the critical task of extracting informative signal components in scenarios with potentially imprecise expert annotations. Finally, it can be adapted to mitigate the need for subject-specific calibration. These attributes render the proposed algorithm suitable for real-time applications, including closed-loop BCIs for addressing the pressing challenge of neurorehabilitation.</p>","PeriodicalId":711,"journal":{"name":"Moscow University Physics Bulletin","volume":"79 2 supplement","pages":"S890 - S897"},"PeriodicalIF":0.4,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143667882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
