Using Python:

Compute the Mean Square Error (MSE): ???=1?∑??=0(??−??)2 M S E = 1 n ∑ i = 0 n ( X i − Y i ) 2 . Where ?? X i and ?? Y i imply the ? i -th elements in ? X and ? Y , and ? n is the number of elements in ? X and ? Y (for example, create one-dimensional arrays ? X and ? Y with 5 elements).

Answer #1

The python code will be

def mse(x,y):
#returns mean squared error between two arrays x and y of length n
n=len(x)
val=0 #to store the final result
for i in range(n):
val=val+(x[i]-y[i])**2
  
return val/n
  
x=[1,2,3,4,5]
y=[2,3,4,5,6]

print(mse(x,y))

the output and screenshot is

Do give a thumbs up and in case there are doubts leave a comment.
