K-Nearest Neighbor (KNN) Algorithm - GeeksforGeeks
When you want to classify a data point into a category like spam or not spam, the KNN algorithm looks at the K closest points in the dataset. These closest points are called neighbors.

What is the k-nearest neighbors (KNN) algorithm? - IBM
The k-nearest neighbors (KNN) algorithm is a non-parametric, supervised learning classifier, which uses proximity to make classifications or predictions about the grouping of an individual data point.

K-Nearest Neighbor (KNN) Algorithm: Use Cases and Tips - G2
KNN classifies or predicts outcomes based on the closest data points it can find in its training set. Think of it as asking your neighbors for advice; whoever’s closest gets the biggest say.

What is K-Nearest Neighbors Algorithm? - ServiceNow
The k-nearest neighbors (KNN) algorithm offers a straightforward and efficient solution to this problem. Instead of requiring complex calculations up front, KNN works by storing all the data and then making predictions for new data based on how similar it is to existing data.

The KNN Algorithm - Explanation, Opportunities, Limitations
KNN works by evaluating the local minimum of a target function to approximate an unknown function with the desired precision and accuracy. The algorithm identifies the “neighborhood” of a new input (e.g., a new data point) by assessing its distance to known data points.
