K-Nearest-Neighbor
K-Nearest Neighbor (KNN) is a fundamental supervised machine learning algorithm widely used for classification and regression tasks. It operates on the principle of proximity, classifying a data point based on the majority class of its ‘k’ closest neighbors in the feature space. KNN is non-parametric, meaning it does not assume any underlying distribution of the data, making it versatile across various applications, from image recognition to recommendation systems. The simplicity of KNN, combined with its effectiveness, has made it a popular choice for both beginners and experienced data scientists alike.
