Question 1 Multiple Choice (Single Answer)

Which of the following is not a common metric for evaluating classification models?

  1. Accuracy
  2. Precision
  3. Recall
  4. F1 score
Question 2 Multiple Choice (Single Answer)

What is the formula for calculating accuracy?

  1. Accuracy = (True Positives + True Negatives) / (True Positives + False Positives + True Negatives + False Negatives)
  2. Accuracy = (True Positives + True Negatives) / (Total Samples)
  3. Accuracy = (True Positives + False Positives) / (Total Samples)
  4. Accuracy = (True Negatives + False Negatives) / (Total Samples)
Question 3 Multiple Choice (Single Answer)

What is the formula for calculating precision?

  1. Precision = True Positives / (True Positives + False Positives)
  2. Precision = True Positives / (True Positives + False Negatives)
  3. Precision = True Negatives / (True Negatives + False Positives)
  4. Precision = True Negatives / (True Negatives + False Negatives)
Question 4 Multiple Choice (Single Answer)

What is the formula for calculating recall?

  1. Recall = True Positives / (True Positives + False Negatives)
  2. Recall = True Positives / (True Positives + False Positives)
  3. Recall = True Negatives / (True Negatives + False Positives)
  4. Recall = True Negatives / (True Negatives + False Negatives)
Question 5 Multiple Choice (Single Answer)

What is the formula for calculating F1 score?

  1. F1 score = 2 * (Precision * Recall) / (Precision + Recall)
  2. F1 score = (Precision + Recall) / 2
  3. F1 score = Precision * Recall
  4. F1 score = Precision / Recall

Question 8 Multiple Choice (Single Answer)

What is the formula for calculating mean squared error?

  1. Mean squared error = (1/n) * Σ(y_i - μ_i)^2
  2. Mean squared error = (1/n) * Σ(y_i - μ_i)
  3. Mean squared error = Σ(y_i - μ_i)^2
  4. Mean squared error = Σ(y_i - μ_i)
Question 9 Multiple Choice (Single Answer)

What is the formula for calculating root mean squared error?

  1. Root mean squared error = √sqrt((1/n) * Σ(y_i - μ_i)^2)
  2. Root mean squared error = √sqrt((1/n) * Σ(y_i - μ_i))
  3. Root mean squared error = √sqrt(Σ(y_i - μ_i)^2)
  4. Root mean squared error = √sqrt(Σ(y_i - μ_i))
