Question

4. You must fit a single node decision tree to predict weight from height and gender to the data provided below. What is the optimum decision variable and threshold value to use? What is the optimal RSS? Show your work. Height(cm) Gender Weight(kg) 150 Female 155 Female 70 160 Male 70 Female 60 180 Male

Answer 1

solution:

Optimum Decision Variable:-

It is a quantity that the decision-maker controls. The OptQuest Engine manipulates decision variables in search of their optimal values. Decision variables are added to an optimization problem  by instantiating a decision variable and adding the instance to the optimization using the COptQuestOptimization::AddVariable() method.

For example, in an optimization model for labor scheduling, the number of nurses to employ during the morning shift in an emergency room may be a decision variable.

Optimal RSS:-

Received Signal Strength (RSS) measurements are used for Connectivity-based localization schemes compute the node positions using proximity information collected within the network.Connectivity data can be obtained by comparing the RSS against a threshold.
