In this paper the ID3 decision tree learning algorithm is implemented with the help of an example which includes the training set of two weeks. The basic calculations are used to calculate the classification re
This paper details the ID3 classification algorithm. Very simply, ID3 builds a decision tree from a fixed set of examples. The resulting tree is used to classify future samples. The example has several attributes and belongs to a class (like yes or no). The leaf nodes of the decision tree...

1. The information theory basis of decision tree ID3 algorithm The machine learning algorithm is very old. As a code farmer, I often knock on if, else if, else, but I already use the idea of decision tree. Just have you thought about it, there are so many conditions, which co...
Here we are going to take liberty with our data. After doing a bit of research on our markets, we have decided that each country has its own language and each belongs to a region of the globe. We can use our ID3 algorithm to decide if the country, region, or language is important ...

Since each data owner cannot directly divide the local dataset according to the best attributes selected, a consortium blockchain and a homomorphic encryption algorithm are employed to ensure the privacy and usability of the distributed data. Security analysis indicates that our scheme can preserve the...
