Q1. What is regression ? how it works
Ans. 
Regression is a statistical method used to analyze the relationship between variables and predict outcomes.
• Regression models the relationship between a dependent variable and one or more independent variables.

• It works by finding the best-fit line that minimizes the sum of squared differences between the actual and predicted values.

• Examples include linear regression, polynomial regression, and logistic regression.

Q1. Describe a decision tree
Ans. 
A decision tree is a flowchart-like model that shows the possible outcomes of a decision based on certain conditions.
• It is a tree-like structure with nodes representing decisions and branches representing outcomes

• Each node has a condition that determines which branch to follow

• It is commonly used in machine learning for classification and regression tasks

• Example: A decision tree for predicting whether a customer will bu...read more

Q2. What is random forest
Ans. 
Random forest is an ensemble learning method for classification, regression and other tasks.
• Random forest builds multiple decision trees and combines their outputs to improve accuracy.

• It is a popular machine learning algorithm due to its high accuracy and ability to handle large datasets.

• Random forest can be used for both classification and regression tasks.

• It is resistant to overfitting and can handle missing data.

Q3. What is neural network
Ans. 
Neural network is a type of machine learning algorithm inspired by the structure and function of the human brain.
• Consists of layers of interconnected nodes that process information

• Used for tasks such as image recognition, natural language processing, and prediction

• Can be trained using supervised, unsupervised, or reinforcement learning

• Examples include convolutional neural networks, recurrent neural networks, and deep n
