It is proposed to use the accuracy of the classification of HSI (as the most common problem solved with the help of HSI) to control the permissible level of introduced distortions instead of the indicator of visual imperceptibility. We need to increase the volume or robustness of embedded information while maintaining acceptable classification quality. For this it is proposed to change the embedding parameters for different HSI channels in proportion to their significance in classification. As an example, three fundamentally different methods of embedding information are considered: the method based on quantization index modulation(QIM), the method based on spread spectrum and the method based on interpolation. Experiments have shown the absolute advantage of the proposed approach over the standard one (parameter values constant for each channel) for all three methods. Experiments have confirmed that the proposed approach makes it possible to fill a significant part of the volume of the HSI (about 3/4 for the method based on QIM) almost without deterioration in the quality of classification. And for the interpolation-based method, it is possible not only not to worsen, but to improve the quality of classification along with the embedding of hidden information.","PeriodicalId":296438,"journal":{"name":"2023 IX International Conference on Information Technology and Nanotechnology (ITNT)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123811558","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 long-term existence of modern space remote sensing systems (up to 20 years) requires the performance of these maneuvers with minimal fuel consumption. Modern electric propulsion systems have a high specific impulse (15000-70000 m/s), which ensures the fulfillment of these requirements. In addition, they meet the requirement of the operation duration. In recent decades, the optimal control theory by the electric propulsion spacecraft in near-Earth orbits has been developed. However, obtaining optimal control programs is a long and difficult computational process. The work devotes to the analysis of existing optimal solutions and the development of stable algorithms for the remote sensing control programs formation for a wide class of dynamic maneuvers.","PeriodicalId":296438,"journal":{"name":"2023 IX International Conference on Information Technology and Nanotechnology (ITNT)","volume":"91 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125152786","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 subject of the study is the methods and means of monitoring the motor activity of patients with amputation of the lower extremities. To solve the tasks set in the work, a clinical analysis of gait was used in terms of temporal, spatial, kinematic, dynamic and energy parameters. The structure of the robotic complex is proposed, which makes it possible to increase the efficiency of adjusting the parameters of the prosthesis by organizing biofeedback, taking into account the individual characteristics of the patient. The use of the structure of the rehabilitation robotic complex proposed by the authors will reduce mechanical loads in the process of finishing operations when creating a lower limb prosthesis.

NARX realizes the paradigm of the autoregressive moving average (ARIMA) model class. Some difficulties and restrictions are known when modeling noisy and nonstationary time series with seasonal patterns of long time delay by NARX. On the example of time series of ionospheric parameters, the paper shows that the developed procedure of wavelet filtering allows us to obtain an adequate NARX model. An algorithm for wavelet filtering was constructed and a method for obtaining stochastic thresholds was suggested. The efficiency of the method was shown for the problems of detection of ionospheric inhomogeneities based on the data of ionospheric layer F2 critical frequency.

The collected data is subjected to statistical and intellectual analysis. To improve the quality of input data, intelligent methods are actively used for data recovery, including for filling missing values in data. However, the task of improving the quality of the obtained data remains relevant. Also acute is the issue associated with resource intensity and high time costs when using existing solutions to fill in missing values in data. The article proposes a modified method of filling missing values in data, based on the k-nearest neighbors’ method, and its implementation that solves these problems. The method has been successfully tested on two data sets: on the generated data and on the data of the OpenWeatherMap service that provides weather data, on the example of the city of Ufa. The proposed method showed better results compared to existing methods: simple data recovery (based on the calculation of the mean, median, mode), k-nearest neighbors-based methods, random forest, predictive mean matching and the method of building regression models.","PeriodicalId":296438,"journal":{"name":"2023 IX International Conference on Information Technology and Nanotechnology (ITNT)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131556154","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}
