WebAlpha (α) is the penalty term that denotes the amount of shrinkage (or constraint) that will be implemented in the equation. With alpha set to zero, you will find that this is the equivalent of the linear regression model from equation 1.2, and a larger value penalizes the optimization function. WebWhere α is a tuning parameter that seeks to balance between the fit of the model to the data and the magnitude of the model's coefficients: A tiny α imposes no penalty on the coefficient size, and is equivalent to a normal linear regression. Increasing α penalizes the coefficients and thus shrinks them towards zero.

WebChapter 9. Decision Trees. Tree-based models are a class of nonparametric algorithms that work by partitioning the feature space into a number of smaller (non-overlapping) regions with similar response values using a set of splitting rules.
