How to solve the scaling issue faced by knn
WebFeb 23, 2024 · One of those is K Nearest Neighbors, or KNN—a popular supervised machine learning algorithm used for solving classification and regression problems. The main objective of the KNN algorithm is to predict the classification of a new sample point based on data points that are separated into several individual classes. WebFeb 5, 2024 · Why Scalability Matters. Scalability matters in machine learning because: Training a model can take a long time. A model can be so big that it can't fit into the working memory of the training device. Even if we decide to buy a big machine with lots of memory and processing power, it is going to be somehow more expensive than using a lot of ...
