Question

Consider the hypothesis space defined over instances shown below, we characterize each

hypothesis (apple taste) by 4-tuples. Please hand trace the ID3 classifier to build a decision

tree, then predict the target value Taste=Sweet/Tart for the following instances:

a) <Red, High, Some, No>

b) <Red, Low, Some, Yes>

c) <Yellow, Low, Some, No>

d) <Green, High, None, No>

e) <Green, Mid, Some, Yes>

Now suppose the actual taste of the five apples above are actually “Sweet, Sweet,

Sweet, Tart, Tart”, what is the accuracy of the decision tree? Please show all the steps

and include the corresponding confusion matrix for accuracy calculation.

The table below provides a detailed classification of different melons based on several characteristics such as color, crispiness, presence of spots, fragrance, and taste. | Melon | Color | Crispiness | Spot | Fragrant | Taste | |-------|--------|------------|-------|----------|-------| | 1 | Red | High | None | Yes | Sweet | | 2 | Red | High | None | No | Sweet | | 3 | Yellow | High | None | Yes | Sweet | | 4 | Yellow | Mid | Some | No | Tart | | 5 | Yellow | Low | None | No | Sweet | | 6 | Yellow | Mid | Some | Yes | Tart | | 7 | Green | Low | Some | No | Sweet | | 8 | Red | Low | None | Yes | Tart | | 9 | Red | Low | None | No | Sweet | | 10 | Yellow | Mid | None | Yes | Sweet | **Explanation of Columns:** - **Melon:** Each row represents a distinct melon with a numerical identifier. - **Color:** The exterior color of the melon, which can be red, yellow, or green. - **Crispiness:** The texture quality, rated as high, mid, or low. - **Spot:** The presence of spots on the melon, indicated as some or none. - **Fragrant:** Whether the melon has a noticeable fragrance, denoted by yes or no. - **Taste:** The flavor of the melon, categorized as sweet or tart.
