!!! Overview [{$pagename}] is the amount that the estimate of the [Mapping function] will change if different [Training dataset] was used. The [Mapping function] is estimated from the [Training dataset] by some machine learning algorithm, so we should expect the [algorithm] to have some variance. Ideally, it should not change too much from one [Training dataset] to the next, meaning that the [algorithm] is good at picking out the hidden underlying mapping between the inputs and the output variables. [Machine Learning] [algorithms] that have a high [[{$pagename}] are strongly in uenced by the specifics of the [Training dataset]. This means that the specifics of the training have in uences the number and types of parameters used to characterize the mapping function. * Low [{$pagename}] - Suggests small changes to the estimate of the [Mapping function] with changes to the [Training dataset] * High [{$pagename}] - Suggests large changes to the estimate of the [Mapping function] with changes to the [Training dataset] (Referred to a [Overfitting]) Examples of low-[{$pagename}] [Machine Learning] [algorithms] include: * Linear Regression * Linear Discriminant Analysis * [Logistic Regression] Examples of high-[{$pagename}] [Machine Learning] [algorithms] include: * Decision Trees * k-Nearest Neighbors * Support Vector Machines. !!
