Q. In a case study involving predicting house prices, which feature would be most relevant?
A.
The color of the house
B.
The number of bedrooms
C.
The owner's name
D.
The year the house was built
Solution
The number of bedrooms is a relevant feature that can significantly impact house prices in a predictive model.
Q. In a regression problem, what does the term 'overfitting' refer to?
A.
The model performs well on training data but poorly on unseen data
B.
The model is too simple to capture the underlying trend
C.
The model has too few features
D.
The model is perfectly accurate
Solution
Overfitting occurs when a model learns the training data too well, capturing noise instead of the underlying pattern, leading to poor performance on new data.
Correct Answer:
A
— The model performs well on training data but poorly on unseen data
Q. What does the term 'confusion matrix' refer to in classification tasks?
A.
A matrix that shows the relationship between features
B.
A table used to evaluate the performance of a classification model
C.
A method for dimensionality reduction
D.
A technique for data normalization
Solution
A confusion matrix is a table that summarizes the performance of a classification model by showing true positives, false positives, true negatives, and false negatives.
Correct Answer:
B
— A table used to evaluate the performance of a classification model
