The difficulties with the k-nearest neighbor algorithm is option c. none of the above.

<h3>What problems does the K-nearest Neighbor algorithm have?</h3>

An unlabelled point is given a label based on its proximity to all other nearby labelled points. This is how it works. Its main drawbacks are that picking the "right" value of K is challenging and that it is highly computationally inefficient.

Hence, The supervised machine learning technique known as the k-nearest neighbors (KNN) can be used to tackle classification and regression issues. It is simple to use and comprehend, but it has the important problem of becoming noticeably slower as the amount of data in use increases.

Write a Python 3 program to read from a .csv file containing rates from power companies. Your program should determine the avera
aliya0001 [1]

Answer:

In python:

file = open("rates.csv", "r")

ratecount = 0

ratesum = 0

mylist = []

rates = file.readlines()

for nums in rates:

     num = nums.rstrip('\n')

     mylist.append(int(num))

     for i in num:

           ratesum= ratesum + int(i)

           ratecount = ratecount + 1

print("Maximum Rate: "+str(max(mylist)))

print("Minimum Rate: "+str(min(mylist)))

print("Average Rate: "+str(ratesum/ratecount))

Explanation:

This opens the csv file

file = open("rates.csv", "r")

This initializes the number of rates in the file

ratecount = 0

This initializes the sum of the rates

ratesum = 0

This initializes an empty list

mylist = []

This reads the rates into lines

rates = file.readlines()

This iterates through the rates (as a string)

for nums in rates:

This removes the newline character \n in the rates

     num = nums.rstrip('\n')

This appends the rates (as an integer) to the empty list

     mylist.append(int(num))

The following counts the rates in the file and also sum them up

<em>      for i in num: </em>

<em>            ratesum= ratesum + int(i) </em>

<em>            ratecount = ratecount + 1 </em>

This prints the maximum of the rates

print("Maximum Rate: "+str(max(mylist)))

This prints the minimum of the rates

print("Minimum Rate: "+str(min(mylist)))

This calculates and prints the average rate

print("Average Rate: "+str(ratesum/ratecount))
