K-Nearest Neighbors (KNN) Algorithm

The K-Nearest Neighbors (KNN) algorithm is a type of supervised learning algorithm that uses the neighboring data points to classify new data points.
One advantage of the KNN algorithm is that it is simple to implement and can be effective for small datasets.
The KNN algorithm belongs to instance-based learning, which means it makes predictions based on the similarity of new data points to existing data points.
The main application of the KNN algorithm is in classification problems, such as image classification, text classification, and recommender systems.
The KNN algorithm is non-parametric, meaning it doesn't make any assumptions about the underlying data distribution, making it flexible and robust.
The KNN algorithm is sensitive to the choice of the value of K, which is the number of nearest neighbors to consider.
The key characteristic of the KNN algorithm is that it uses the distance or similarity between data points to make predictions.
The purpose of the training data in the KNN algorithm is to provide a set of labeled data points that can be used to classify new data points.
Common applications of the KNN algorithm include image classification, text classification, recommender systems, and anomaly detection.
A limitation of the KNN algorithm is that it can be computationally expensive for large datasets, and it is sensitive to noisy data and outliers.
