Exploring the rules of the decision tree using Graph objects

  • Big idea -- Machine learning models are difficult to explain and interpret.
  • Small idea -- Especially, in understanding the insights offered by the large decision tree models, such as, "How the rules affect the the entity" is challenging with complex models.
  • Birds eye view of the idea -- We plan to undo the complexity of the large decision tree model and explain the relationship of between the insight within the model with respect to the data.
  • Technical details -- Train a dataset on a simple machine learning model such as decision tree. Using graphs / networks understand the rules of the decision tree.
  • What's next -- Often, the visualized network results in formation of various clusters. The future direction can explore the possibilities in identifying similarity between the structures.

🎯 Objective

  • The objective of this research study is to develop a method for explaining large decision rules using a graph network and how it affects data samples.
  • We specifically try apply this technique on the IRIS dataset.
  • The objective of this research study is to develop a method for intepreting the large decision rules and how it affects data samples. We demonstrate our techniques with the use of IRIS dataset.

💪 Challenge

  • In the real world dataset, it is a challenge to identify patterns and various factors that interact in explaining the decisions made for specific instance.

🧪 Solution

  • With large set of complicated rules, it is difficult to understand the interactions.
  • We use explainable methods such as decision trees.
  • Identify the commonality between the entities by visualizing the rules between the trees.
