OBJECT DETECTION SYSTEMS FOR DETERMINING CAR MODELS AND BODY COLOR: COMPREHENSIVE COMPARATIVE ANALYSIS AND PRACTICAL INTEGRATION BASED ON REAL IMAGES UNDER UZBEKISTAN CONDITIONS
type: item
description: This paper presents a practical solution for real-time recognition of vehicle model and body color on real-world CCTV streams in Uzbekistan. The dataset was annotated in CVAT and cleaned; to ensure fair evaluation, we applied a camera-wise train/val/test split (preventing cross-camera leakage). On the same dataset, we fine-tuned YOLOv8-l, DETR (ResNet-101), and CenterNet, and analyzed the quality–speed trade-off from a deployment perspective. Using detector-produced bounding boxes as ROIs, we integrated a fast color module into the pipeline based on a combined LAB+HSV approach. For inference threshold selection, we employed a practical method grounded in the F1–Confidence curve. The system operates robustly with multi-camera RTSP streams, supports auto-reconnect and resource monitoring (CPU/RAM/IO and, when available, GPU), and is ready for ONNX/TensorRT export. The results demonstrate practical applicability in traffic monitoring, security, and intelligent video surveillance systems.

OLORA+: A HYBRID APPROACH TO LOW-RANK ADAPTATION
type: item
description: This paper introduces and analyzes OLoRA+, a novel parameter-efficient fine-tuning method that enhances Low-Rank Adaptation (LoRA) by combining the orthonormal initialization of OLoRA with the differential learning rate optimization of LoRA+. The study compared the performance of OLoRA+ against the standard OLoRA baseline on the TinyLlama-1.1B-Chat-v1.0 model. Using a subset of the alpaca dataset, a collection of 52K instruction-following demonstrations, with 1000 samples for training and 500 for testing, model performance was assessed using evaluation loss, BLEU, and ROUGE metrics. The obtained results show that OLoRA+ consistently outperforms the OLoRA baseline across all considered metrics. Additionally, the study reveals that OLoRA+ is effective with learning rate ratios both greater and less than one, uncovering a novel trade-off between "Refinement" and "Exploration" learning strategies. This confirms OLoRA+'s potential as a more versatile and powerful approach for LLM adaptation under limited resource conditions.

DEEP LEARNING APPROACHES IN CLASSIFICATION OF ECG SIGNALS FOR CARDIOVASCULAR DISEASE DETECTION
type: item
description: Cardiovascular diseases (CVDs) remain the leading cause of mortality worldwide, emphasizing the critical need for early detection and accurate diagnosis. Electrocardiography (ECG) provides a noninvasive and cost-effective means of assessing cardiac health; however, manual interpretation is time-consuming and prone to human error. Recent advances in deep learning have shown great promise in automating ECG signal analysis by leveraging powerful feature extraction and classification capabilities. This study investigates multiple deep learning architectures, including convolutional neural networks (CNNs), hybrid CNN–LSTM models, and Transformer-based approaches, applied to benchmark ECG datasets. A comprehensive workflow is developed, consisting of data acquisition, preprocessing, beat segmentation, deep learning-based feature extraction, classification, and performance evaluation. Comparative experiments demonstrate that while CNNs effectively capture morphological features, the CNN–LSTM hybrid yields enhanced performance by modeling temporal dependencies. The Transformer-based model achieves the highest accuracy, sensitivity, and specificity, highlighting its ability to capture long-range dependencies in ECG signals. The results confirm the potential of advanced deep learning frameworks in supporting reliable, automated CVD detection. Future directions include cross-dataset validation, multimodal integration, and optimization for deployment on wearable and embedded platforms.

HYBRID AI FOR GASTRIC DIAGNOSTICS: MULTI-MODAL FUSION AND INTERPRETABILITY FOR EARLY ULCER AND CANCER DETECTION
type: item
description: This study investigates the development of hybrid Artificial Intelligence (AI) models for the early and accurate diagnosis of gastric ulcer and gastric cancer. Traditional diagnostic methods such as endoscopy and biopsy, though widely used, face limitations including inter-observer variability, sampling errors, and delays in diagnosis. To address these challenges, two novel hybrid AI architectures are proposed: the Deep Feature-Attention SVM (DFA-SVM) and the Multi-Modal Fuzzy-Fusion Network (M2F2-Net). These models integrate multi-modal data sources, including endoscopic images, histopathology slides, and structured clinical records, while employing attention mechanisms, fuzzy logic, and interpretable AI approaches to enhance diagnostic performance. Experimental evaluation using the conceptual GIMIC-12K dataset demonstrates that M2F2-Net achieves superior performance, particularly in early gastric cancer detection, by significantly reducing false negatives and improving sensitivity. The findings highlight the transformative potential of hybrid AI in improving patient outcomes, optimizing healthcare efficiency, and supporting explainable decision-making in clinical practice.

SVM ALGORITMI ASOSIDA SUN’IY NUTQNI ANIQLASH VA IDENTIFIKATSIYA QILISHNING INTELLEKTUAL YONDASHUVI
type: item
description: Ushbu maqolada sun’iy nutqni aniqlash va uni identifikatsiya qilish uchun SVM (Support Vector Machine) algoritmiga asoslangan yondashuv taklif etiladi. Taklif etilgan pipeline 8 kHz chastotada yozilgan nutq yozuvlarini qayta ishlashga moslashtirilgan bo‘lib, akustik xususiyatlar sifatida quyidagi parametrlar tanlangan: MFCC₁–MFCC₁₃, F₀, H, Eₗₒg, ZCR, ΔMFCC, Jitter va HNR. Ushbu parametrlar nutq signalining kepstral, fonatsion va prosodik xususiyatlarini qamrab olib, model uchun informativ vakillikni ta’minlaydi. Xususiyatlar freym darajasida ajratilib, utterance (gap) darajasida statistik agregatsiyalar (o‘rtacha qiymat, dispersiya, percentillar, diapazon) yordamida fiks uzunlikdagi vektorlarga aylantiriladi. Olingan vektorlar z-score normalizatsiyasi orqali standartlashtiriladi. Klassifikatsiya bosqichida esa RBF yadrosiga ega SVM modeli qo‘llaniladi. Model gipermetrlari nested k-fold cross-validation yordamida optimallashtiriladi, sinflar o‘rtasidagi nomutanosiblik esa sinf og‘irliklari orqali balanslanadi. Baholash jarayonida Accuracy, Macro-F1, ROC-AUC hamda anti-spoofing vazifasiga xos EER/HTER mezonlari qo‘llanilgan. Shuningdek, ablyatsiya tahlili(modelning qaysi qismi yoki qaysi xususiyat(lar) haqiqatan foyda berayotganini aniqlash uchun u(lar)ni tizimli ravishda olib tashlab (yoki alohida qo‘shib) ko‘rsatkichlar qanday o‘zgarishini solishtirish usuli) orqali har bir parametrning model natijalariga qo‘shgan hissasi alohida o‘rganilgan. Eksperimental natijalar shuni ko‘rsatdiki, MFCC parametrlarini ΔMFCC, Jitter va HNR kabi qo‘shimcha xususiyatlar bilan boyitish modelning diskriminativ qobiliyatini sezilarli darajada oshiradi. Taklif etilgan yondashuv yengil, barqaror va real vaqtli tizimlarga integratsiyaga tayyor bo‘lib, sun’iy nutqni aniqlashda yuqori aniqlikni ta’minlaydi.

POST-QUANTUM CRYPTOGRAPHY AND ITS MATHEMATICAL FOUNDATIONS
type: item
description: The rapid advancement of quantum computing technologies has posed a significant challenge to the security and reliability of classical cryptographic systems, particularly those based on integer factorization, discrete logarithms, and elliptic curve cryptography. Post-quantum cryptography (PQC) has therefore emerged as one of the most crucial research directions in modern information security, focusing on the design and analysis of cryptographic algorithms that remain secure even in the presence of powerful quantum adversaries. This article provides a comprehensive overview of post-quantum cryptography and its mathematical foundations, highlighting the theoretical underpinnings, algorithmic approaches, and current trends in this evolving field. The discussion begins with an examination of the fundamental mathematical problems upon which post-quantum cryptographic constructions are based, including lattice-based problems, error-correcting codes, multivariate polynomial equations, isogenies of elliptic curves, and hash-based cryptographic techniques. These problems are believed to be resistant to both classical and quantum attacks, making them suitable candidates for the next generation of secure communication protocols. The article also explores the complexity assumptions, reductions, and hardness proofs that establish the security of post-quantum schemes, thereby emphasizing the importance of rigorous mathematical reasoning in cryptographic design. Furthermore, the article analyzes the advantages and limitations of different PQC families, considering aspects such as key sizes, computational efficiency, implementation challenges, and resistance to side-channel attacks. Special attention is given to the ongoing standardization process led by the National Institute of Standards and Technology (NIST), which aims to select algorithms for widespread adoption across governmental and commercial applications. The paper also reflects on the future prospects of post-quantum cry…

IJTIMOIY TARMOQLARDA KONTENT ASOSIDAGI MEDIA TA’SIRINI O‘RGANISH: RAQAMLI IZ MA’LUMOTLARINI YIG‘ISHNING API, MA’LUMOT HADYA QILISH VA KUZATISH USULLARI
type: item
description: Ijtimoiy tarmoqlar ta’sirini o‘rganish sohasida aniq kontentning roli yetarlicha tadqiq etilmagan. Bunga qisman ilgari kommunikatsiya fanida ijtimoiy tarmoq kontentiga bevosita kirish imkonini beradigan usullar mavjud emas edi. Raqamli iz ma’lumotlari (Digital Trace Data, DTD) ijtimoiy tarmoqlardan foydalanish jarayonida yaratilgan matnli va audiovizual kontentni yoritib berib, avval imkoni bo‘lmagan darajada alohida foydalanuvchi darajasida kontentdan foydalanishni tahlil qilish imkonini yaratadi. Biroq, raqamli iz ma’lumotlari maxsus ilmiy tadqiqot uchun ishlab chiqilmagani sababli, ularni yig‘ish va tahlil qilishda bir qator noaniqliklar mavjud. Ushbu maqola, raqamli iz ma’lumotlarini yig‘ishning uchta usuli – API lar, foydalanuvchi ma’lumotlarini topshirish (data donation) va kuzatish (tracking) – kommunikatsiya tadqiqotining uchta muhim yo‘nalishida (soxta axborot, algoritmik usullar) qanday qo‘llanishi mumkinligi haqida umumiy ma’lumot beradi. Biz ijtimoiy tarmoqlardagi mukammal bo‘lmagan kontent ma’lumotlarini qanday yig‘ish va ularni mazmunli ko‘rsatkichlarga aylantirish mumkinligi masalasini ko‘rib chiqamiz. Maqola yakunida har bir usulni amalga oshirish bo‘yicha yechimlar muhokama qilinadi hamda ularning afzalliklari va kamchiliklari taqqoslanadi.

AUTOMATIC SEGMENTATION OF MALIGNANT SKIN TUMORS IN DERMOSCOPIC IMAGES USING U-NET ARCHITECTURE
type: item
description: Oncological diseases remain one of the most pressing health problems on a global scale. According to data for the last 10 years, the prevalence of cancer has increased by almost 26%, and according to the age-specific standardized morbidity rate (ASIR), by 15%. As overall morbidity rates increase globally, the mortality rate is gradually decreasing. The decrease in cancer-related mortality by 2% is explained by the effectiveness of the use of automated diagnostic processes in early detection and treatment strategies. However, these indicators are very low compared to cases of infection. This indicates the need for the deep application of information technologies in the field of medicine. In particular, it plays an important role in analyzing medical images and optimizing early diagnostic processes using artificial intelligence. In this study, one of the tasks that serves as the basis for the accuracy of automated diagnostics using medical images - the problem of segmentation of medical images - was considered. In this case, the U-Net model based on deep learning was used as an object for the purpose of automatic detection of malignant skin tumors, in particular melanoma, based on dermoscopic images and segmentation of their boundaries, and an accuracy of 92% was achieved.

With five UNESCO World Heritage sites, over 7,000 historical monuments, and a growing tourism sector that contributes 4.5% to national GDP, the country has significant potential to integrate sustainable tourism practices. However, inequalities in regional tourism development, weak governance structures, and limited implementation of ESG principles remain significant challenges. This article assesses Uzbekistan's regional tourism potential for sustainable integration, analyzing statistical indicators, regional case studies (Samarkand, Bukhara, Khiva, Tashkent) and international best practices. Recommendations are provided for policymakers, local authorities and the private sector.

ABOUT ONE METHOD OF FORMING CADASTRAL INFORMATION OF TELECOMMUNICATION FACILITIES
type: item
description: This article presents a method for creating a digital cadastre of telecommunications facilities based on the principles of single data entry, continuous event-driven updating, spatiotemporal modeling, and integration with departmental information systems. The proposed architecture improves the reliability and manageability of cadastral data, as well as regulatory compatibility with national and international standards. The article discusses the stages of method implementation, including data collection, standardization, database formation, quality control, and monitoring. It is shown that the application of the developed approach improves the integral quality of data, reduces updating time, reduces the number of duplicate records, and increases infrastructure coverage. The practical significance lies in the formation of a reliable information foundation for planning and regulating the development of telecommunications networks within the digital economy.

TADBIR TURIZMI ORQALI MAVSUMIY TURIZM OQIMLARINI MUVOZANATLASHTIRISH VA IJTIMOIY FAROVONLIKNI OSHIRISH IMKONIYATLARI
type: item
description: Tadbir turizmi turli yo‘nalishlarda turli xil samaradorlikka ega bo‘lsa-da, turizm mavsumiyligini yumshatish uchun strategik yondashuv sifatida paydo bo‘ladi. Tadqiqotlar shuni ko‘rsatadiki, tadbirlar yil davomida turizmga bo‘lgan talab taqsimotini muvozanatlashda yordam berishi mumkin, buni Makedoniyaning Sharqiy mintaqasida ko‘rish mumkin, bu yerda tadbir turizmi mavsumiylikning past darajasi va muvozanatli tashrif buyuruvchilar oqimiga hissa qo‘shgan [1]. Biroq, tadbirlar va mavsumiylikni boshqarish o‘rtasidagi bog‘liqlik murakkab bo‘lib, yil bo‘yi attraksionlarning atigi 39 foizi maxsus tadbirlarga mezbonlik qiladi, ayniqsa mahalliy hamjamiyatlarga mo‘ljallanmagan davrlarda [2]. Mavsumga qarshi turizm strategiyalari, shu jumladan madaniy, diniy va konferensiya turizmi bilan bir qatorda tadbirlar turizmi sayyohlarning kelishi va xarajatlaridagi vaqtinchalik nomutanosibliklarni bartaraf etish uchun tizimli yondashuvlarni ifodalaydi [3]. Shunga qaramay, kuchliroq mavsumiylik namunalari ishonchsiz turizm talabi prognozlari bilan bog‘liq bo‘lib, qo‘llaniladigan yumshatish strategiyalaridan qat’i nazar, rejalashtirish harakatlarini murakkablashtiradi [4]. Ushbu topilmalar shuni ko‘rsatadiki, tadbir turizmi mavsumiylikni kamaytirishga hissa qo‘shishi mumkin, ammo uning samaradorligi strategik harakatlar va mahalliy bozor sharoitlariga bog‘liq.
