Question
What is a typical application of KNN?Answer areaPredicting stock pricesImage recognitionNatural language processingClustering
Solution
A typical application of KNN (K-Nearest Neighbors) is Image Recognition. This is because KNN is a type of instance-based learning, or lazy learning, where the function is only approximated locally and all computation is deferred until function evaluation. It can be used for classification and regression. In image recognition, KNN can classify images based on their nearest neighbors in the feature space.
