A decision tree is a graphic tool that represents conditions and their resulting actions. It consists of a directed acyclic graph (rooted tree) in which the non-terminal edges represent a set of conditions evaluated sequentially from the root. A node is a decision point where a condition is ...
Specifically, tree-based models achieved a pooled AUC of 0.745 (95% CIs 0.572–0.917, I2 = 97.31%), compared to 0.615 (95% CIs 0.552–0.768, I2 = 0%) for neural networks. Additionally, only one study applied a SVM model in this demographic, yielding an AUC of 0.67 (95%...
Chapter 3 discussed binary classification for the specific purpose for spam filtering using a dataset from SpamAssassin. It introduces the reader to the naïve Bayes classifier and the principles of text mining suing the tm package in R. Some of the example codes could have been better commented...
Due to its superior sensitivity, breast MRI (bMRI) has been established as an important additional diagnostic tool in the breast clinic and is used for screening in patients with an elevated risk for breast cancer. Breast MRI, however, is a complex tool,

Mdl = fitctree(___,Name,Value) fits a tree with additional options specified by one or more name-value pair arguments, using any of the previous syntaxes. For example, you can specify the algorithm used to find the best split on a categorical predictor, grow a cross-validated tree, or ...
In some embodiments, the supported decision tree has nodes that correspond to a feature of a decision and edges corresponding to a value of the feature. The nodes of the supported decision tree may be identified from the elements of the plurality of decision chains and ordered based at least ...
