Mashinaviy o‘qitishda belgilar fazosi juda katta bo‘lib ketganda belgilar fazosi o‘lchamlarini qisqartirish muhim ahamiyat kasb etadi. Ushbu maqolada belgilar fazosini qisqartirishning ikkita eng mashhur usullari BKT (Bosh komponent tahlili) va CHDT (chiziqli diskriminant tahlili) qiyosiy tahlili keltirilgan. Umuman olganda, CHDT-ga asoslangan algoritmlar BKTga asoslangan algoritmlardan ustundir. Ushbu maqolada biz bu har doim ham shunday emasligini ko‘rsatamiz. Bizning xulosamiz shundan iboratki, agar o‘quv ma’lumotlar to‘plami kichik bo‘lsa, BKT CHDT dan ustun bo‘lishi mumkin, shuningdek, BKT turli xil o‘quv ma’lumotlar to‘plamlariga nisbatan sezgir emas. Kalit so‘zlar: Bosh komponent, chiziqli diskriminant, kovariatsiya matritsasi,dispersiya, xos qiymat. 55

Management and Future Technologies journal.umft.uz COMPARATIVE ANALYSIS OF SIGN SPACE REDUCTION METHODS IN SIGN RECOGNITION A bstract: In machine learning, reducing the size of the character space becomes important when the character space becomes too large. This article presents a comparative analysis of the two most popular methods of character space reduction, BKT (Principal Component Analysis) and CHDT (Linear Discriminant Analysis). In general, CHDT-based algorithms outperform BKT-based algorithms. In this article, we will show that this is not always the case. Our conclusion is that BKT can outperform CHDT if the training dataset is small, and also BKT is insensitive to different training datasets. Keywords: Principal component, linear discriminant, covariance matrix, variance, eigenvalue.
