决策树(Decision Tree)模型 在复杂的决策情况中,往往需要多层次或多阶段的决策。当一个阶段决策完成后,可能有m种新的不同自然状态发生;每种自然状态下,都有m个新的策略可选择,选择后产生不同的结果并再次面临新的自然状态,继续产生一系列的决策过程,这种决策被称为序列决策或多级决策。 此时,如果继续遵循上述的决策准则或采用效益矩阵分析问题,就容
6.1.1 Decision tree Decision tree is a non-parametric supervised learning method used for classification and regression. This method is very popular in ML and data mining due to its intelligibility and simplicity. The method aims to create a model that predicts the value of a target variable by...

One tree contains the analysis for purchasing, and another tree contains the analysis for the customer rewards program. If you use the Decision Trees algorithm to create an association model, the algorithm creates a separate tree for each product that is being predicte...
Decision-tree theory was adopted in the critical analysis of the importance and significance of telemedicine in healthcare sectors. The principles of the decision-tree model were integrated in the use of telemedicine in the healthcare sector. Also, the criticisms of the application of decision-tree...
