Q1. What is the detailed working mechanism of Decision Trees, and how are they utilized for classification tasks?
Ans. 
Decision Trees are a popular machine learning algorithm used for classification tasks by recursively splitting the data based on feature values.
• Decision Trees work by recursively splitting the data based on feature values to create a tree-like structure.

• At each node, the algorithm selects the feature that best splits the data into purest possible subsets.

• This process continues until a stopping criterion is met, such as...read more

Q1. Explanation of decision trees
Ans. 
Decision trees are a type of supervised machine learning algorithm used for classification and regression tasks.
• Decision trees are hierarchical structures where each internal node represents a feature or attribute, each branch represents a decision rule, and each leaf node represents the outcome.

• They are easy to interpret and visualize, making them popular for decision-making processes.

• Decision trees can handle both nu...read more

Q2. Explanation of svm
Ans. 
Support Vector Machine (SVM) is a supervised machine learning algorithm used for classification and regression tasks.
• SVM finds the hyperplane that best separates the classes in a high-dimensional space

• It works by maximizing the margin between the closest data points from different classes

• SVM can handle non-linear data by using kernel functions to map data into higher dimensions

• It is effective for small to medium-sized
