Predictive validation methods
WebAlso, this approach is not very scalable. Hence, in practice, external validation is usually skipped. In this article, we propose the twin-sample validation as a methodology to validate results of unsupervised learning in addition to internal validation, which is very similar to external validation, but without the need for human inputs. WebNov 3, 2024 · Similarly to cross-validation techniques (Chapter @ref (cross-validation)), the bootstrap resampling method can be used to measure the accuracy of a predictive model. Additionally, it can be used to measure the uncertainty associated with any statistical estimator. Bootstrap resampling consists of repeatedly selecting a sample of n …
