NettetAdvantages of KNN . The advantages of KNN are: KNN is known as the “Lazy Learner” since there is no training period (Instance-based learning). During the training phase, it does not learn anything. The training data isn't used to derive any discriminative functions. In other words, it does not require any training. Nettet18. jun. 2024 · One advantage of KNN is once the Arduino has some example data it is instantly ready to classify! We’ve released a new Arduino library so you can include KNN in your sketches quickly and easily, with no off-device training or additional tools required.
