K-Nearest Neighbor algorithm is one of the simplest and still popular machine learning models out there. If a simple model can do the job, I would never go for a harder one. Simply because simple models are easier to explain to the stakeholders.
This tutorial will cover everything you need to know to use a KNN classifier and a KNN Regressor for your project. This tutorial starts with a overview on how K nearest Neighbors algorithm works, then developing a classifier in Python's sklearn library with KNN Classifier, and developing a regression model in Python's sklearn library with KNN regressor.
Both the models will include a detailed process on how you can choose the right K for your model.
