2. Which of the following is a type of supervised learning?

Clustering

Dimensionality Reduction

Regression

None of the above

Regression, where the algorithm predicts a continuous output variable, is a type of supervised learning.

Explanation

Regression, where the algorithm predicts a continuous output variable, is a type of supervised learning.

3. How are the predictions made in a Decision Tree algorithm?

Based on nearest neighbors

Based on tree-like model structure

Based on density

Based on distance from centroids

In a decision tree, for predicting the class of the given dataset, the algorithm starts from the root node of the tree.

Explanation

In a decision tree, for predicting the class of the given dataset, the algorithm starts from the root node of the tree.

4. Which of the following best describes the term 'underfitting' in supervised learning?

When a model learns too much detail

When a model learns too little detail

When a model is too complex

When a model is too simple

Underfitting refers to a model that can neither model the training data nor generalize to new data.

Explanation

Underfitting refers to a model that can neither model the training data nor generalize to new data.

5. Which algorithm is commonly used for classification in supervised learning?

K-Means

DBSCAN

Decision Tree

None of the above

A decision tree is a supervised learning algorithm that is perfect for classification problems, as it's able to order classes on a precise level.

Explanation

A decision tree is a supervised learning algorithm that is perfect for classification problems, as it's able to order classes on a precise level.

6. Which algorithm is used for boosting in supervised learning?

Naive Bayes

AdaBoost

Random Forests

K-Means

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.

Explanation

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.

7. What is the goal of a confusion matrix in supervised learning?

To visualize the performance of an algorithm

To reduce computational complexity

To improve data visualization

All of the above

The goal of a confusion matrix is to visualize the performance of an algorithm in terms of true and false positives and negatives.

Explanation

The goal of a confusion matrix is to visualize the performance of an algorithm in terms of true and false positives and negatives.

8. Which of the following is a drawback of Decision Trees?

They are prone to overfitting

They can only handle numeric data

They are sensitive to outliers

All of the above

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.

Explanation

9. What does the Support Vector Machine (SVM) algorithm do in supervised learning?

Group similar data

Predict future data

Classify data

Generate new data

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.

Explanation

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.

10. In the context of supervised learning, what is overfitting?

When a model performs well on unseen data

When a model performs poorly on unseen data

When a model learns too much detail

When a model learns too little detail

Overfitting occurs when the model cannot generalize and fits too closely to the training dataset instead.

Explanation

Overfitting occurs when the model cannot generalize and fits too closely to the training dataset instead.
