Indeed, modern publicly-available datasets typically contain images of mostly middle-aged and Caucasian people, which cause most algorithms to fail on photos of older people or children, rarer ethnicities, poor-quality images, etc. Detection of such anomaly data and its subsequent rejection helps to improve the classification accuracy. We propose a novel algorithm, at the first stage of which a convolutional neural network is used to detect anomalies in input images. This network is trained on a specially created set of rare data. The second stage is the sequential analysis of neural descriptors extracted from input faces to improve the computational efficiency of classification. An experimental study on the VGGFace2 and MS-Celeb-1M datasets using neural network descriptors, including contemporary InsightFace models, demonstrated the effectiveness of the proposed algorithm.","PeriodicalId":296438,"journal":{"name":"2023 IX International Conference on Information Technology and Nanotechnology (ITNT)","volume":"200 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":"121072235","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 influence exerted by space weather (SW) factors on the current state of the SSC systems is also studied. An increasing dependence between the spacecraft parameters and changes in geomagnetic activity is shown, which intensifies in the subpolar regions of the orbit.","PeriodicalId":296438,"journal":{"name":"2023 IX International Conference on Information Technology and Nanotechnology (ITNT)","volume":"18 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":"114257563","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}

It is possible to ensemble other algorithms in a different quantity. Reinforcement learning is a promising area in machine learning. An important unsolved problem of reinforcement learning is the generalization of complex problems, and their solution using meta-algorithms.

Two types of quality criteria are considered, based on the properties of the histogram of the tested image and evaluating the similarity of the latter with the binarized image. The first type includes the criteria used in the well-known OTSU method, the PUN entropy test, as well as the new CHP test. The second type includes the SSIM image similarity test, the W2 gradient test, and the correlated test COR. It is substantiated that for a fixed quality criterion, the binarization procedure is reduced only to searching for a threshold from a certain set of values that maximizes this criterion. It is shown that the criterion PSNR of the closeness of images is unsuitable in this procedure; because the optimal threshold value obtained by this criterion does not depend on the tested image and equal to 127.","PeriodicalId":296438,"journal":{"name":"2023 IX International Conference on Information Technology and Nanotechnology (ITNT)","volume":"100 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":"122666383","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}

To increase efficiency, an approach based on deep contextual video compression is used. In addition to the difference frame, this approach relies heavily on specialized algorithms for extracting additional information characterizing the difference of closely spaced frames. The use of context in this case makes it possible to achieve a better quality of reconstruction of video sequences, in particular for complex textures with a large number of high frequencies. This implies that the proposed method can potentially lead to significant savings in storage and transmission costs while maintaining high-quality video output. This article presents the results of computational experiments to evaluate the effectiveness of the investigated method of deep contextual video compression on real video sequences. Experimental findings demonstrate the advantages of the considered technique in PSNRR/bpp coordinates when compared to the performance of three common video codecs: H.264, H.265, and VP9.","PeriodicalId":296438,"journal":{"name":"2023 IX International Conference on Information Technology and Nanotechnology (ITNT)","volume":"111 3S 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":"116361838","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}
