56.Giperbolik tangens faollashtirish funksiyasi noto'g'ri berilgan qatorni ko'rsating?

J : f(x) = tanh(x) = e^x – e^-x / e^x + e^-x­

57.Logistik regressiya usuli mashinali o'qitishning qaysi masalasi bilan bog'liq?

58.Mashinali o'qitishda chiziqli regressiyaning maqsadi nima?

J: Logistic regression is specifically meant for classification, it is useful in understanding how a set of independent variables affect the out come of the dependent variable.

(tarjimasi) “Logistik regressiya, ayniqsa, tasniflash uchun mo'ljallangan, mustaqil o'zgaruvchilar to'plamining bog'liq o'zgaruvchining chiqishiga qanday ta'sir qilishini tushunishda foydalidir.”

59.Gradient tushishi (Gradient descent) chiziqli regressiyada nima maqsadda qo'llaniladi?

J 1 : Qiymat funksiyasi (cost function) qiymatlarning eng kichik qiymatlarini aiqlash uchun.

• 
  J 2 : It is a very effective and simple approach to fit linear models. Stochastic gradient descent is particularly useful when the
