Q. What is the primary goal of model deployment in machine learning?
A.
To train the model on new data
B.
To make the model available for use in production
C.
To evaluate the model's performance
D.
To visualize the model's predictions
Solution
The primary goal of model deployment is to make the model available for use in production environments, allowing it to provide predictions or insights based on new data.
Correct Answer:
B
— To make the model available for use in production
Q. What is the primary goal of the K-means clustering algorithm?
A.
Minimize the distance between points in the same cluster
B.
Maximize the distance between different clusters
C.
Both A and B
D.
None of the above
Solution
The primary goal of K-means clustering is to minimize the distance between points in the same cluster while maximizing the distance between different clusters.
Q. What is the primary method used to determine the optimal number of clusters in K-means?
A.
Elbow method
B.
Silhouette analysis
C.
Cross-validation
D.
Grid search
Solution
The elbow method is a common technique used to determine the optimal number of clusters in K-means by plotting the explained variance against the number of clusters.
Q. What is the primary purpose of a binary tree's post-order traversal?
A.
To evaluate expressions
B.
To print nodes in sorted order
C.
To find the height of the tree
D.
To find the maximum element
Solution
Post-order traversal is primarily used to evaluate expressions represented by binary trees, as it processes the left and right children before the parent node.
