- B.
Predict future data
- C.
Classify data
- D.
Generate new data
Correct Answer
C. Classify dataExplanation
The main objective of the SVM algorithm is to find the optimal hyperplane in an N-dimensional space that can separate the data points in different classes in the feature space.Rate this question:

In the context of supervised learning, what is overfitting?
- A.
When a model performs well on unseen data
- B.
When a model performs poorly on unseen data
- C.
When a model learns too much detail
- D.
When a model learns too little detail
Correct Answer
C. When a model learns too much detailExplanation
Overfitting occurs when the model cannot generalize and fits too closely to the training dataset instead.Rate this question:

Which of the following best describes the term 'underfitting' in supervised learning?
- A.
When a model learns too much detail
- B.
When a model learns too little detail
- C.
When a model is too complex
- D.
When a model is too simple
Correct Answer
B. When a model learns too little detailExplanation
Underfitting refers to a model that can neither model the training data nor generalize to new data.Rate this question:

Which algorithm is used for boosting in supervised learning?
- A.
Naive Bayes
- B.
AdaBoost
- C.
Random Forests
- D.
K-Means
Correct Answer
B. AdaBoostExplanation
AdaBoost is a boosting algorithm that also works on the principle of the stagewise addition method where multiple weak learners are used for getting strong learners.Rate this question:

- 9.
How are the predictions made in a Decision Tree algorithm?
- A.
Based on nearest neighbors
- B.
Based on tree-like model structure
- C.
Based on density
- D.
Based on distance from centroids
Correct Answer
B. Based on tree-like model structureExplanation
In a decision tree, for predicting the class of the given dataset, the algorithm starts from the root node of the tree.Rate this question:

- 10.
Which of the following is a drawback of Decision Trees?
- A.
They are prone to overfitting
- B.
They can only handle numeric data
- C.
They are sensitive to outliers
- D.
All of the above
Correct Answer
A. They are prone to overfittingExplanation
Among the most common and prominent disadvantages of decision trees are that it's a high variance algorithm. This means that it can easily overfit because it has no inherent mechanism to stop, thereby creating complex decision rules.Rate this question:
