Sample questions from this paper

The first 3 questions as they appear in the paper. Answers are shown only after you take it.

Q1
What is the primary role of Model Evaluation in the AI Project Cycle?
  1. A To feed clean data into the machine learning algorithm
  2. B To test the trained model's performance on unseen data and validate its reliability
  3. C To write Python code for deployment in mobile applications
  4. D To collect raw data from external IoT sensors
Q2
In the context of the AI Project Cycle, model evaluation acts as a 'report card' because it:
  1. A Calculates the monetary cost of training the AI model
  2. B Provides a quantitative feedback loop to fine-tune model performance
  3. C Automatically eliminates the need for data preprocessing
  4. D Guarantees 100% accuracy in all operational conditions
Q3
Why is evaluating an AI model on the exact same dataset used for training considered bad practice?
  1. A It causes the training execution time to double
  2. B It leads to false optimism because the model might have memorized the training data (overfitting)
  3. C Training data contains no positive class instances
  4. D Evaluation algorithms only accept CSV files as input
