10 Questions
Explain the difference between supervised learning and unsupervised learning in machine learning.
Supervised learning uses labeled data to train the model to predict the output, while unsupervised learning uses unlabeled data to find hidden patterns or intrinsic structures within the data.
Define regression algorithms in the context of supervised machine learning and provide an example of a regression algorithm.
Regression algorithms are used for predicting continuous variables when there is a relationship between the input and output variables. An example of a regression algorithm is Linear Regression, which models the relationship between the independent and dependent variables using a linear equation.
What are the types of supervised machine learning algorithms, and how are they further categorized?
The types of supervised machine learning algorithms are classification and regression. They are further categorized into algorithms used for predicting categorical output (classification) and algorithms used for predicting continuous variables (regression).
Explain the purpose of classification algorithms in supervised machine learning and provide an example of a classification algorithm.
Classification algorithms are used when the output variable is categorical, such as binary classes like Yes/No or multiclass categories like different types of fruits. An example of a classification algorithm is K-Nearest Neighbors (KNN), which classifies data points based on the majority vote of their neighbors.
What is the role of K nearest neighbors (KNN) in classification algorithms, and how does it make predictions?
K nearest neighbors (KNN) is a classification algorithm that classifies a data point based on how its neighbors are classified. It makes predictions by calculating the majority class among the K nearest neighbors of the data point.
Which type of supervised learning algorithm is used for the prediction of continuous variables?
