WebIn decision tree construction, concept of purity is based on the fraction of the data elements in the group that belong to the subset. A decision tree is constructed by a split that divides the rows into child nodes. If a tree is considered "binary," its nodes can only have two children. The same procedure is used to split the child groups. Webalgorithm compared to the state-of-the-art algorithm[22]. This paper is organized as follows. InSection II, we cover our experimental design including the synthesis and sequencing information. We also explain the proposed iterative soft decoding algorithm and how each technique works. In Section III, we show the superiority of the proposed methods
