Question 1 of 8
What is the primary difference between parameters and hyperparameters in machine learning?
Parameters are more important than hyperparameters
Hyperparameters are learned from the data, while parameters are set manually
Parameters are learned from the data, while hyperparameters are set prior to learning
There is no difference between parameters and hyperparameters
Question 2 of 8
Which of the following is NOT a common consequence of poorly set hyperparameters?
Underfitting
Overfitting
Poor generalization on unseen data
Faster training times
Question 3 of 8
In a Random Forest model, which of the following is a hyperparameter?
The split points in individual decision trees
The number of trees (n_estimators)
The predicted class labels
The feature importances
Question 4 of 8
Why is the choice of kernel in Support Vector Machines (SVMs) considered a hyperparameter?
It's learned automatically from the data
It doesn't affect the model's performance
It's set prior to training and affects how the model learns
It's only relevant for classification tasks
Question 5 of 8
Which hyperparameter tuning method exhaustively searches through all possible combinations of hyperparameters?
Random Search
Bayesian Optimization
Grid Search
Genetic Algorithm
Question 6 of 8
In a scenario with limited computational resources and a large hyperparameter space, which method would likely be most efficient?
Exhaustive Search
Manual Tuning
Question 7 of 8
What is a key advantage of Bayesian Optimization in hyperparameter tuning?
It always finds the global optimum
It requires no prior knowledge of the hyperparameters
It efficiently uses information from previous evaluations to guide future searches
It's the fastest method for all types of models
Question 8 of 8
In the context of hyperparameter tuning, what does "cross-validation" primarily help with?
Speeding up the tuning process
Reducing the number of hyperparameters to tune
Providing a more reliable estimate of model performance
Automatically selecting the best hyperparameters
