Lazy learner algorithm
WebLazy Learners. As the name suggests, such kind of learners waits for the testing data to be appeared after storing the training data. Classification is done only after getting the testing data. They spend less time on training but more time on predicting. Examples of lazy learners are K-nearest neighbor and case-based reasoning. Eager Learners Web1 sep. 2024 · K-NN is a non-parametric algorithm, which means it does not make any assumptions on underlying data.. It is also called a lazy learner algorithm because it does not learn from the training set immediately instead it stores the dataset and at the time of classification, it performs an action on the dataset.
