What Is KNN Algorithm ?
One of the easiest supervised machine learning
methods for classification is K-Nearest
Neighbors. A data point is classified depending
on the types of its neighbors. It archives all
cases in its database and groups fresh cases
according to characteristics in typical.

Why Is KNN Algorithm Important?
Because it generates extremely accurate
predictions, the K-Nearest Neighbors Algorithm
can compete with the most accurate models. As a
result, the KNN technique can be used for
applications that need excellent accuracy but
don't need a model that humans can read. The
distance measurement affects how accurate the
predictions are.

How Does KNN Algorithm Work?
Using K-Nearest Neighbors, The algorithm
estimates the distances between a query and a
separate example in the data, determines the K
models closest to the query, and then votes for
the label that is used the most frequently.

Applications of KNN Algorithm
It is used in various contexts, including
writing, image, and video recognition. The
K-Nearest Neighbors Algorithm is useful when
labeled data is too costly or impossible to
gather. It is also highly accurate in several
prediction-type applications.
