Which of the following statement is true about k-NN algorithm?

Mathematics

BaLLatris [955]3 years ago

The answer is D. All of the above.

The computational complexity of K-NN increases as the size of the training data set increase and the algorithm gets significantly slower as the number of examples and independent variables increase.

Also, K-NN is a non-parametric machine learning algorithm and as such makes no assumption about the functional form of the problem at hand.

The algorithm works better with data of the same scale, hence normalizing the data prior to applying the algorithm is recommended.

15-a=20 what value would make this true

sergejj [24]

Answer:

a = -5

Step-by-step explanation:

15 - a = 20

Move the constant of 15 to the other side by subtracting it.

-a = 5

Divide by -1 to make a positive.

a = -5

Check.

15 - (-5) = 20

15 + 5 = 20

20 = 20

A dilation produces a smaller figure. Which is a possible scale factor?

iragen [17]

We know that
if a dilation produces a smaller figure
then
0< scale factor <1
so
case A) -2------> the scale factor must be a positive number
case B) 1/3----> 0< 1/3 <1---> is a possible scale factor
case C) 1------> this scale factor does not not produce a smaller figure, it produces the same figure
case D) 4----> this scale factor produces a larger figure

the answer is
1/3

Len [333]

Answer:

A:(-2,-3)

B:(-4.009,1.018) And (-2,-3)

C:x≈0,1.61878812

Step-by-step explanation:

I found the equations

g(x)=e^x+1

p(x)=5/2x+2

f(x)=-2x-7

plugged it in on a graph found the answer to find g(x) all you need to do is know the parent function y=e^2(exponential) and I found where the lines intersect for part A and B and or p(x)=g(x) I did e^x+1=(5/2)x+2
