SO can someone explain in a short concise response what KNN is & its implementation?

Expert Solution

Step 1: K-Nearest Neighbors:

K-Nearest Neighbors is a straightforward and versatile algorithm that makes predictions based on the similarity of data points in a training dataset. It's a good starting point for many machine learning tasks but has its limitations, especially in high-dimensional and noisy data scenarios. Proper tuning of the hyperparameter K and careful preprocessing of data are essential for its success.
