32.7.2. Decision Trees and Random Forest

Try these first

1. 1.

   What does a Decision Tree do in predicting construction delays?

   Hint

   Think about how choices can lead to different outcomes.

2. 2.

   What is one advantage of using Random Forests?

   Hint

   How might teamwork improve results?

3. 3.

   What is a Decision Tree used for?

   • To visualize construction materials
   • To predict outcomes based on data
   • To calculate project budgets

   Hint

   Consider the function of offering choices based on various criteria.

4. 4.

   True or False: A Random Forest uses a single tree for predictions.

   • True
   • False

   Hint

   Recall how forests consist of more than one tree.

5. 5.

   Design a sample Decision Tree to predict construction delays based on hypothetical factors: 'Budget Limit', 'Weather Forecast', and 'Worker Availability'.

   Hint

   Think about how each factor might influence each other.

6. 6.

   Explain how you would utilize both Decision Trees and Random Forests in a real-world scenario within civil engineering, considering their respective strengths.

   Hint

   Recall the benefits of simplifying decisions first, then combining insights for greater accuracy.
