Q. Which algorithm is commonly used for classification tasks?
A.
Linear Regression
B.
K-Nearest Neighbors
C.
Principal Component Analysis
D.
K-Means Clustering
Solution
K-Nearest Neighbors (KNN) is a popular algorithm used for classification tasks, where it classifies data points based on the classes of their nearest neighbors.
Q. Which algorithm is more memory efficient for deep graphs?
A.
BFS
B.
DFS
C.
Both are equal
D.
Neither is efficient
Solution
DFS is generally more memory efficient for deep graphs because it uses a stack and does not need to store all nodes at the current level like BFS does.
Q. Which algorithm is typically faster for making predictions, Decision Trees or Random Forests?
A.
Decision Trees
B.
Random Forests
C.
Both are equally fast
D.
It depends on the dataset size
Solution
Decision Trees are generally faster for making predictions because they involve a single tree, while Random Forests require aggregating results from multiple trees.
Q. Which algorithm is typically used for linear regression?
A.
K-Nearest Neighbors
B.
Support Vector Machines
C.
Ordinary Least Squares
D.
Decision Trees
Solution
Ordinary Least Squares (OLS) is a common algorithm used for linear regression to minimize the sum of squared differences between observed and predicted values.
