The Modified ID3 algorithm is implemented in python programming by using a reduced feature set of the Hepatitis C virus dataset (Hoffmann et al. in J Lab Precis Med 3:58, 2018) along with standard ML algorithms, such as ID3, support vector machine, random forest, and other recent states ...
This is a simple implementation of the ID3 + C4.5 algorithm for decision tree learning. The current example uses geometric figures for training and testing. The algorithm is implemented in Python 3.9.6. Project was created as a part of the course "Methods of Artificial Intelligence " at the ...
