Quiz 12

Machine learning models should work automatically without the need for the

user to manually set the hyperparameters.

• True

• False

While training your regression model using Gradient Decent, you noticed that the

value of loss increases with epochs, this behavior can be due to high learning

rate.

• True

• False

Draw: Normal (expected) regression

Draw: Overfitting regression

from scipy import stats
x = [5,7,8,7,2,17,2,9,4,11,12,9,6]
y = [99,86,87,88,111,86,103,87,94,78,77,85,86]

complete code to find :slope, intercept ??

which Equation is polynomial regreesion

• y=Ax+B

• y=Ax1+Bx2+c

• y=Ax1+Bx2^2+c

Cleaning Empty Cells which function we use ?

• df.dropna()

• df.fillna(130, inplace = True)

• df.loc[7, 'Duration'] = 45

• A & B

Removing Duplicates which function we use ?

• df.loc[7, 'Duration'] = 45

• df.dropna()

• df.duplicated()

• none of them

import numpy as np

arr1 = np.array([1, 2, 3])

arr2 = np.array([4, 5, 6])

arr = np.concatenate((arr1, arr2))

print(arr)

what is output ?

import numpy as np

arr = np.array([3, 2, 0, 1])

print(np.sort(arr))

what is output
