Unsupervised learning
O’qituvchisiz o’qitish (unsupervised learning) – bu mashinani o’qitish usulidan
biri bo’lib, bunda modelni oldindan aniq bo’lgan ma’lumotlar bilan o’qitish amalga
oshirilmaydi, aksincha obyekt parametrlarini (ma'lumotlarni) toppish uchun modelga
o'z ustida ishlashga imkon yaratib beriladi.
Supervised learning usuliga qaraganda murakkab usul hisoblanadi va bashoratlash
jarayoni avtomatik lekin noaniqroq bo’lishi mumkin.
Unsupervised learning usulida asosan “klasterlash” masalasi yechiladi.
