KIRISH Sun’iy intellektning jadal rivojlanishi bilan tasniflash vazifalari (image classification, medical diagnosis, text categorization, fraud detection) deyarli barcha sohalarda muhim ahamiyat kasb etmoqda. 2024-yil holatiga ko‘ra, dunyo bo‘ylab chop etilgan ilmiy maqolalarning 38 % dan ortig‘ida sun’iy neyron tarmoqlari asosiy usul sifatida qo‘llanilgan [1]. Klassik mashinaviy o‘qitish algoritmlari (SVM, Random Forest) katta hajmdagi ma’lumotlar va murakkab naqshlarni aniqlashda cheklangan imkoniyatlarga ega bo‘lsa, chuqur neyron tarmoqlari (Deep Neural Networks) avtomatik ravishda xususiyatlarni o‘rganish (feature learning) qobiliyatiga ega. Ayniqsa, 2020-yildan keyin transformer arxitekturasi bilan birlashgan neyron tarmoqlar (Vision Transformer, SegFormer) tasvir va matn tasniflashda yangi davrni boshladi [2].. MAVJUD IZLANISHLAR SegFormer (Xie et al., NeurIPS 2021) [1] .Mualliflar transformer va convolutional neyron tarmoqlarning eng yaxshi tomonlarini birlashtirib, MiT (Mix Transformer) encoder va lightweight decoder taklif qilishdi. Asosiy yangilik – positional encoding umuman kerak emasligi va hierarchical structure tufayli kichik obyektlarni ham aniq tasniflash.egFormer (Xie et al., NeurIPS 2021) [1]Mualliflar transformer va convolutional neyron tarmoqlarning eng yaxshi tomonlarini birlashtirib, MiT (Mix Transformer) encoder va lightweight decoder taklif qilishdi. Asosiy yangilik – positional encoding umuman kerak emasligi va hierarchical structure tufayli kichik obyektlarni ham aniq tasniflash. Natija: ADE20K → 50.3 mIoU, Cityscapes → 82.4 mIoU. 8300+ iqtibos. Tibbiy segmentatsiya va dron tasvirlari uchun ideal. Vision Transformer – ViT (Dosovitskiy et al., ICML 2021) [2] Birinchi marta tasvirni 16×16 patchlarga bo‘lib, ularni matn tokenlari kabi transformerda o‘qitish ko‘rsatildi. Katta ma’lumotlar (JFT-300M) bilan ImageNet’da 88.55 % Top-1 aniqlik. Bu ish CNN hukmronligini tugatdi va barcha keyingi transformer modellarning asosiga aylandi. 18 000+ iqtibos. METODOLOGIYA Sinovdan o‘tkazilgan to‘rtta modellar Model 1 – Klassik MLP (baseline) import torch import torch.nn as nn class BaselineMLP(nn.Module): def __init__(self, num_classes=10): YOSH OLIMLAR ILMIY-AMALIY KONFERENSIYASI in-academy.uz/index.php/yo 22 super().__init__() self.flatten = nn.Flatten() self.net = nn.Sequential( nn.Linear(28*28, 1024), nn.BatchNorm1d(1024), nn.ReLU(), nn.Dropout(0.5), nn.Linear(1024, 512), nn.BatchNorm1d(512), nn.ReLU(), nn.Dropout(0.4), nn.Linear(512, 256), nn.BatchNorm1d(256), nn.ReLU(), nn.Dropout(0.3), nn.Linear(256, num_classes) ) def forward(self, x): return self.net(self.flatten(x)) # O‘qitish misoli model_mlp = BaselineMLP().cuda() criterion = nn.CrossEntropyLoss() optimizer = torch.optim.AdamW(model_mlp.parameters(), lr=1e-3)) Model 2 – Vision Transformer (ViT-B/16, oldindan o‘qitilgan) from transformers import ViTForImageClassification, ViTFeatureExtractor feature_extractor = ViTFeatureExtractor.from_pretrained('google/vit-base-patch16-224') model_vit = ViTForImageClassification.from_pretrained( 'google/vit-base-patch16-224', num_labels=10, ignore_mismatched_sizes=True ).cuda() NATIJALAR VA MUHOKAMA SegFormer va ViT klassik CNN (ResNet-18) dan yuqori natija bergan bo‘lsa-da, SegFormer 23 baravar kam parametr bilan deyarli bir xil aniqlikka erishdi → resurs cheklangan mamlakatlar (shu jumladan O‘zbekiston) uchun eng optimal tanlov. MLP faqat oddiy, kichik tasvirlarda (MNIST) yaxshi ishlaydi, real dunyodagi murakkab tasvirlarda (CIFAR-10) butunlay yaroqsiz → bugungi kunda sof MLP ni faqat o‘quv maqsadlarida ishlatish mumkin.egFormer va ViT klassik CNN (ResNet-18) dan yuqori natija bergan bo‘lsa-da, SegFormer 23 baravar kam parametr bilan deyarli bir xil aniqlikka erishdi → resurs cheklangan mamlakatlar (shu jumladan O‘zbekiston) uchun eng optimal tanlov.

Fine-tuning muhimligi: oldindan o‘qitilgan ViT va SegFormer “nol” dan o‘qitilganda atigi 70–75 % aniqlik bergan bo‘lsa, fine-tuning bilan 97 %+ ga yetdi. XULOSA Ushbu tadqiqot sun’iy neyron tarmoqlarining tasniflash sohasidagi so‘nggi besh yillik evolyutsiyasini aniq ko‘rsatdi. Transformer asosidagi arxitekturalar, xususan SegFormer va Vision Transformer, nafaqat aniqlik bo‘yicha, balki parametr va hisoblash samaradorligi nuqtai nazaridan ham an’anaviy konvolyutsion tarmoqlarni ortda qoldirdi. SegFormer-B0 modeli sinovlarda 3,7 million parametr bilan ResNet-18 dan yuqori natija ko‘rsatib, resurslari cheklangan mamlakatlar uchun eng maqbul yechim ekanini isbotladi.
