Service-Life Study of Polycarbonate Outdoors Using Python with Incomplete Data

Algorithm 1

Input: Training Set ;

   Attribute Set .

Process: Function

01: generate the node

02: if all samples in belong to the same class then

03: sign the node as a leaf node of class; return

04: end if

05: ifor samples in have the same value of then

06: sign the node as a leaf node of the class which the most samples in belong to; return

07: end if

08: select the optimal attribute;

09: for every value of do

10: generate a branch for the node;

   make be a subaggregate of samples in with the value of;

11: ifthen

12: sign the branch node as a leaf node of the class which the most samples in belong to; return

13: else

14: sign as a branch node

15: end if

16: end for

Output: a decision tree with the root node.
