  1. Linear Regression

  2. Logistic Regression

  3. Decision Tree

  4. K-Nearest Neighbors (KNN)


Correct Option: A
Explanation:

Linear Regression is a supervised learning algorithm that models the relationship between a dependent variable and one or more independent variables using a linear equation. It is commonly used for tasks such as predicting house prices, stock market prices, and sales figures.

Which machine learning model is used for classifying data into two or more categories?

  1. Linear Regression

  2. Logistic Regression

  3. Decision Tree

  4. K-Nearest Neighbors (KNN)


Correct Option: B
Explanation:

Logistic Regression is a supervised learning algorithm that models the probability of an event occurring based on a set of independent variables. It is commonly used for tasks such as predicting customer churn, loan default, and medical diagnosis.

Which machine learning model is used for clustering data into groups based on similarities?

  1. Linear Regression

  2. Logistic Regression

  3. K-Means Clustering

  4. Support Vector Machine (SVM)


Correct Option: C
Explanation:

K-Means Clustering is an unsupervised learning algorithm that partitions data into a specified number of clusters based on their similarities. It is commonly used for tasks such as customer segmentation, image segmentation, and anomaly detection.

Which machine learning model is used for finding patterns and relationships in data?

  1. Linear Regression

  2. Logistic Regression

  3. Decision Tree

  4. Principal Component Analysis (PCA)


Correct Option: D
Explanation:

Principal Component Analysis (PCA) is an unsupervised learning algorithm that reduces the dimensionality of data by identifying the principal components, which are the directions of maximum variance in the data. It is commonly used for tasks such as feature extraction, dimensionality reduction, and data visualization.

Which machine learning model is used for detecting anomalies and outliers in data?

  1. Linear Regression

  2. Logistic Regression

  3. Isolation Forest

  4. Support Vector Machine (SVM)


Correct Option: C
Explanation:

Isolation Forest is an unsupervised learning algorithm that detects anomalies and outliers in data by isolating them from the rest of the data points. It is commonly used for tasks such as fraud detection, intrusion detection, and system health monitoring.

Which machine learning model is used for making recommendations based on user preferences?

  1. Linear Regression

  2. Logistic Regression

  3. Collaborative Filtering

  4. Support Vector Machine (SVM)


Correct Option: C
Explanation:

Collaborative Filtering is a machine learning technique that makes recommendations based on the preferences of other users. It is commonly used for tasks such as recommending movies, music, and products to users.

Which machine learning model is used for natural language processing tasks such as text classification and sentiment analysis?

  1. Linear Regression

  2. Logistic Regression

  3. Natural Language Processing (NLP) Models

  4. Support Vector Machine (SVM)


Correct Option: C
Explanation:

Natural Language Processing (NLP) Models are a class of machine learning models that are specifically designed for processing and understanding human language. They are commonly used for tasks such as text classification, sentiment analysis, machine translation, and question answering.

Which machine learning model is used for generating text, code, and other types of data?

  1. Linear Regression

  3. Generative Adversarial Networks (GANs)

  4. Support Vector Machine (SVM)


Correct Option: C
Explanation:

Generative Adversarial Networks (GANs) are a class of machine learning models that are used for generating new data that is similar to the training data. They are commonly used for tasks such as generating images, music, and text.

Which machine learning model is used for reinforcement learning tasks such as playing games and controlling robots?

  1. Linear Regression

  2. Logistic Regression

  3. Q-Learning

  4. Support Vector Machine (SVM)


Correct Option: C
Explanation:

Q-Learning is a reinforcement learning algorithm that learns to take actions in an environment in order to maximize a reward. It is commonly used for tasks such as playing games, controlling robots, and optimizing resource allocation.

Which machine learning model is used for time series forecasting and prediction?

  1. Linear Regression

  2. Logistic Regression

  3. Autoregressive Integrated Moving Average (ARIMA) Models

  4. Support Vector Machine (SVM)


Correct Option: C
Explanation:

Autoregressive Integrated Moving Average (ARIMA) Models are a class of time series models that are used for forecasting and predicting future values based on past values. They are commonly used for tasks such as forecasting sales, predicting stock prices, and analyzing economic data.

Which machine learning model is used for detecting objects in images and videos?

  1. Linear Regression

  2. Logistic Regression

  3. Object Detection Models

  4. Support Vector Machine (SVM)
