You have a dataset of individuals who are classified based on two features: Age and Income, and the
target classification is whether they buy a certain product Yes or No
Given Data:
Age years Income thousands Buys Product YesNo
No
Yes
No
No
Yes
Yes
No
Yes
Determine whether a yearold with an income of thousand is likely to buy the product or not using
KNN with K Assume Euclidean distance for simplicity.
Steps:
Calculate the Euclidean distance between the new individual and each of the given data points.
Identify the three nearest neighbors.
Determine the majority class of these three neighbors.
Predict the class for the new individual based on the majority vote.
Now using the same dataset as above, explore the impact of different K values.
Predict whether a yearold with an income of thousand will buy the product using KNN for K
and K
Hint:
Create a table to organize your distance calculations and neighbor classification.
Point Age years Income thousands Euclidean Distance to New Point Buys Product YesNo
