Understanding the Scenario

You are tasked with developing a decision tree to help people decide whether to walk or use another

mode of transportation for their daily commute. Consider factors such as weather conditions, rush hour,

and distance when making this decision.

Weather conditions may be sunny, rainy and snowy. Rush hours values can be yes$/$no$.$ Distance values

can be short, medium and long.

Evaluation and Analysis

a$)$ Provide a dataset containing $12$ examples. In this dataset, the "Walk" column represents whether the

individual chooses to walk $($Yes$)$ or use another mode of transporta$$on $($No$)$ for their daily commute.

This dataset should have $3$ examples of when people should walk, while they don$$t walk in rest of

the examples. $(5$ points$)$

b$)$ Draw a decision tree for this scenario by using algorithm LEARN$-$DECISION$-$TREE shown in fig $19\mathrm{.}5$ of

your textbook. Use appropriate atributes and decision nodes to represent each step of the decision$-$

making process based on the concept of entropy, remainder and informa$$on gain as discussed in

sec$$on $19\mathrm{.}3\mathrm{.}3$ on page $661-662$ og the textbook. $(10$ points$)$

c$)$ Explain the condi$$ons when the entropy values become $0$ and $1$ for this scenario. $(5$ points$)$
