Go to shape tool, and draw arrow from initial decision, through action and consequence. While the Advertising Campaign example had qualitative numbers to use as indicators of risk versus reward, your decision tree might be more subjective.
Decision Tree Implementation Now that we have the basics of a decision tree, let us go through on of its execution in Python programming. Problem Analysis In the following example we are going to use the famous “Iris Flower” Dataset. Originally published in 1936 at UCI Machine Learning Rep...
为了寻找到最佳空间,我们使用Recursive binary splitting的方法,这个方法是由上至下,并且每一步都是处于当下最好的选择;但它的缺点也是it wont looking ahead and picking a split that will lead to a better tree in some future step。 首先我们选择predictor Xj和cut point,这样我们定义出俩个空间:R_1(j,s...
