5. List down the importance of the Evaluation Process?
Ans. • Evaluation ensures that the model is operating correctly and optimally.
• Evaluation is an initiative to understand how well it achieves its goals.
• Evaluations help to determine what works well and what could be improved in a program
B. Long answer type questions:
1. Differentiate between Prediction and Reality.
Ans. Following are the differences between Prediction and Reality:
a. Prediction is the input given to the machine to receive the expected result of reality.
b. Prediction is the output given to match reality.
c. The prediction is the output which is given by the machine and the reality is the real scenario in which the prediction
has been made.
d. Prediction and reality both can be used interchangeably.
2. Which evaluation metric would be crucial in the following cases? Justify your answer.
a. Mail Spam
b. Gold mining
c. Viral Outbreak
Ans. a. If the model always predicts that the mail is spam, people would not look at it and eventually might lose important
information. False Positive condition would have a high cost.
b. A model saying that there exists treasure at a point and you keep on digging there but it turns out that it is a false
alarm. False Positive case is very costly.
c. A deadly virus has started spreading and the model which is supposed to predict a viral outbreak does not detect it.
The virus might spread widely and infect a lot of people. Hence, False Negative can be dangerous.
3. Select the correct category for each scenario.
1. The AI model predicted that the patient admitted is Covid TP TN FP FN
Positive, and RTPCR test is positive
2. The AI model predicted that the patient admitted is not Covid TP TN FP FN
Positive, and RTPCR test is negative
3. The AI model predicted that the patient admitted is Covid TP TN FP FN
Positive, and RTPCR test is negative
4. The AI model predicted that the patient admitted is not Covid TP TN FP FN
Positive, and RTPCR test is Positive
Storms are frequently experienced all over the world. Storms cause severe damage to people and property. Imagine
that you have come up with an AI based prediction model that predicts whether there will be storms in a given region
or not. Confusion Matrix for the same is:
