WebOr, we could categorize classifiers as “lazy” vs. “eager” learners: Lazy learners: don’t “learn” a decision rule (or function) no learning step involved but require to keep training data around; e.g., K-nearest neighbor classifiers; A third possibility could be “parametric” vs. “non-parametric” (in context of machine ... WebLazy learning is a machine learning technique that delays the learning process until new data is available. This approach is useful when the cost of learning is high or when the amount of training data is small. Lazy learning algorithms do not try to build a model until they are given new data. This contrasts with eager learning algorithms ... WebIn general, unlike eager learning methods, lazy learning (or instance learning) techniques aim at ﬁnding the local optimal solutions for each test instance. Kohavi et al. (1996) and Homayouni et al. (2010) store the training instances and delay the generalization until a new instance arrives. Another work carried out by Galv´an et al.
