WebCross-validation is a way to address the tradeoff between bias and variance. When you obtain a model on a training set, your goal is to minimize variance. You can do this by adding more terms, higher order polynomials, etc. But your true objective is to predict outcomes for points that your model has never seen. WebDec 21, 2012 · Cross-validation gives a measure of out-of-sample accuracy by averaging over several random partitions of the data into training and test samples. It is often used for parameter tuning by doing cross-validation for several (or many) possible values of a parameter and choosing the parameter value that gives the lowest cross-validation …
