Manually train a decision tree based on the following dataset.  a) Please show the detailed process of selecting an attribute to split the instance set  at every node. Gini index should be used to measure the impurity b) Draw the final decision tree.  c) Classify the test instance X= (Outlook = rainy, Temperature = hot, Humidity =  high, Windy = FALSE)

System Model Approaches

The systems model approach is a process-oriented representation that emphasizes the impact or flow of information between modules. The multidisciplinary study of the use of models to design and create systems in business and IT development is known as systems model approach. It models how processes interact and what these processes do, but it does not go into detail about how these processes are implemented. Functional decomposition may be utilized to enhance the models employed in this technique, and they can be coupled to requirements models for additional system partitioning.
