Guruh talabasi Saloxiddinov Sirojbek Azizbek og’li Mashinali o’qitish fanidan 2-Amaliy Ish Mavzu: Ko’p o’zgaruvchilik chiziqlik regressiya

Bunda biz hosil bo’lgan nuqtalar rangini ko’k rangdan qizil rangga o’zgartirib olishimiz mumkin.

Buning uchun plot3(x1,x2,y,'bo','linewidth',4); dan “bo” ni “ro” o’zgartirish kifoya

yuqoridagi dasturda x o’qini biz “Abdimuratov Do’stbek 715-18” y o’qini 'Teacher:Elnur Islomovich' z o’qini 'Machine learning'

hamda title qismini 'Mashinali oqitish 3-kurs” deb nomlab oldik va “run and advance” buyrug’i berilsa quyidagi natijani olamiz.

Xulosa

Men bu amaliy ishni bajarish davomida ko’p o’zgaruvchili chiziqli regressiya ustida amallar bajarib o’tdim. Buning uchun o’qituvchi tomonidan o’rgatilgan amallar ustida ish olib bordim hamda video darslardan foydalandim.
