What does 'accuracy' mean when measuring an AI agent's performance?
Accuracy is how often the AI agent's answers or actions are correct compared to the true or expected results.

Why is 'relevance' important when evaluating an AI agent's responses?
Relevance means the AI agent's answers are related and useful to the question or task, not just correct but also meaningful.

      (1/5)
      1. What does accuracy measure when evaluating an AI agent's answers?
      easy
      A. How many answers are related but not exact
      B. How fast the agent responds
      C. How many answers are exactly correct
      D. How many answers are generated

      Solution

      1. Step 1: Understand accuracy definition

        Accuracy counts the number of answers that match the correct ones exactly.

      2. Step 2: Compare with other metrics

        Relevance measures usefulness, not exact correctness, so it is different from accuracy.

      3. Final Answer:

        How many answers are exactly correct -> Option C

      4. Quick Check:

        Accuracy = exact correctness [OK]
      Hint: Accuracy means exact right answers only [OK]
      Common Mistakes:
      • Confusing accuracy with relevance
      • Thinking accuracy measures speed
      • Assuming accuracy counts all related answers
      2. Which of the following is the correct way to calculate accuracy for an AI agent's answers?
      easy
      A. Number of related answers divided by total answers
      B. Number of correct answers divided by total answers
      C. Number of answers generated per second
      D. Number of answers ignored by the agent

      Solution

      1. Step 1: Recall accuracy formula

        Accuracy = (correct answers) / (total answers given).

      2. Step 2: Eliminate incorrect options

        Options about related answers or speed do not define accuracy.

      3. Final Answer:

        Number of correct answers divided by total answers -> Option B

      4. Quick Check:

        Accuracy = correct / total [OK]
      Hint: Accuracy = correct answers ÷ total answers [OK]
      Common Mistakes:
      • Using related answers count instead of correct
      • Mixing speed with accuracy
      • Ignoring total number of answers
      3. Given an AI agent answered 80 questions, 60 were exactly correct, and 10 more were relevant but not exact. What is the accuracy and relevance percentage?
      medium
      A. Accuracy 60%, Relevance 70%
      B. Accuracy 60%, Relevance 87.5%
      C. Accuracy 75%, Relevance 60%
      D. Accuracy 75%, Relevance 87.5%

      Solution

      1. Step 1: Calculate accuracy percentage

        Accuracy = (60 correct / 80 total) * 100 = 75%.

      2. Step 2: Calculate relevance percentage

        Relevance = ((60 correct + 10 relevant) / 80 total) * 100 = 87.5%.

      3. Final Answer:

        Accuracy 75%, Relevance 87.5% -> Option D

      4. Quick Check:

        Accuracy = 75%, Relevance = 87.5% [OK]
      Hint: Add relevant to correct for relevance % [OK]
      Common Mistakes:
      • Mixing accuracy and relevance values
      • Not adding relevant answers for relevance
      • Dividing by wrong total number
      4. An AI agent evaluation code snippet is below. It calculates accuracy but returns 0. What is the bug? 
      correct = 50
total = 0
accuracy = correct / total
print(accuracy)
      medium
      A. Division by zero error due to total being zero
      B. Correct variable is zero, so accuracy is zero
      C. Print statement syntax is wrong
      D. Accuracy should be multiplied by 100

      Solution

      1. Step 1: Identify variables and operation

        correct = 50, total = 0, accuracy = correct / total.

      2. Step 2: Check for division errors

        Dividing by zero (total=0) causes an error or invalid result.

      3. Final Answer:

        Division by zero error due to total being zero -> Option A

      4. Quick Check:

        Division by zero causes error [OK]
      Hint: Check denominator is not zero before dividing [OK]
      Common Mistakes:
      • Ignoring zero division error
      • Thinking print syntax is wrong
      • Assuming accuracy must be multiplied by 100
      5. You want to improve an AI agent's trust by measuring both accuracy and relevance. Which approach best helps achieve this?
      hard
      A. Track exact correct answers and also count useful related answers
      B. Only count answers that are exactly correct
      C. Ignore relevance and focus on speed of answers
      D. Count all answers regardless of correctness or relevance

      Solution

      1. Step 1: Understand trust factors

        Trust improves when answers are both correct and useful (relevant).

      2. Step 2: Choose measurement approach

        Tracking both exact correctness (accuracy) and usefulness (relevance) gives a fuller picture.

      3. Final Answer:

        Track exact correct answers and also count useful related answers -> Option A

      4. Quick Check:

        Measure accuracy + relevance for trust [OK]
      Hint: Measure both exact and useful answers for trust [OK]
      Common Mistakes:
      • Focusing only on exact correctness
      • Ignoring relevance completely
      • Measuring speed instead of quality
