Objective:

Implement classification algorithm in coding form

Familiar with a real world data as input dataset

Simulate a research environment

Requirements:

Please implement KNN algorithm in C++ programming language.

Apply 5-fold cross validation to evaluate the performance of the KNN

Also use the Jaccard Distance for the KNN algorithm

The evaluation need to calculate the accuracy as well as collect TP, FP, TN, FN as indicator so that further analysis is possible.
