K-Nearest Neighbors (KNN)
KNN uses the majority class of k-nearest neighbours for easy and adaptive classification and regression. Non-parametric KNN has no data distribution assumptions. It works best with uneven decision boundaries and performs well for varied jobs. K-Nearest Neighbors (KNN) is an instance-based, or lazy learning algorithm, where the function is only approximated locally, and all computation is deferred until function evaluation. It classifies new cases based on a similarity measure (e.g., distance functions). KNN is widely used in recommendation systems, anomaly detection, and pattern recognition due to its simplicity and effectiveness in handling non-linear data.
Fetures of K-Nearest Neighbors (KNN)
- Instance-Based Learning: KNN is a type of instance-based or lazy learning algorithm, meaning it does not explicitly learn a model. Instead, it memorizes the training dataset and uses it to make predictions.
- Simplicity: One of the main advantages of KNN is its simplicity. The algorithm is straightforward to understand and easy to implement, requiring no training phase in the traditional sense.
- Non-Parametric: KNN is a non-parametric method, meaning it makes no underlying assumptions about the distribution of the data. This flexibility allows it to be used in a wide variety of situations, including those where the data distribution is unknown or non-standard.
- Flexibility in Distance Choice: The algorithm’s performance can be significantly influenced by the choice of distance metric (e.g., Euclidean, Manhattan, Minkowski). This flexibility allows for customization based on the specific characteristics of the data.
