2. Understanding Machine
Learning
Artificial intelligence, specifically machine learning,
uses algorithms to identify patterns and trends in
unseen data, enabling predictions or decisions.
Machine learning, categorized into supervised learning,
unsupervised learning, and reinforcement learning, is a
subset of artificial intelligence that uses unseen data for
effective learning.

3. 1. Linear Regression:
Linear regression is a crucial predictive modeling algorithm that assumes a
linear relationship between input features and target variables, enabling
continuous numeric outcomes predictions when there's a clear linear trend in
the data.
2. Decision Trees:
Decision trees are versatile algorithms that make decisions based on input
features, generating binary decisions based on each question. These algorithms
are easy to understand and interpret, making them valuable for classification
and regression tasks.

4. 3. Random Forest:
The Random Forest is an ensemble method that combines multiple decision trees
to enhance accuracy and reduce overfitting, making it a robust and effective
approach for complex tasks like feature importance assessment.
4. Support Vector Machines (SVM):
The powerful algorithm, SVM, utilizes kernel functions to find the optimal
hyperplane for regression tasks, effectively handling high-dimensional data and
nonlinear relationships.
5. K-Nearest Neighbors (KNN):
The effective algorithm for regression tasks utilizes the majority class of its k-
nearest neighbors to predict the class or value of a new data point, ensuring
locally-based predictions.

5. When to Use Which Algorithm
· Linear Regression:
This method is utilized for predicting a continuous numeric outcome with a linear
relationship between variables.
· Decision Trees:
Regression tasks are particularly effective when dealing with complex, nonlinear
relationships in data.
· Random Forest:
This option is suitable for those who prioritize accuracy and handling noisy data.

6. · Support Vector Machines (SVM):
This method is suitable for high-dimensional data and when there is a clear
margin between classes.
· K-Nearest Neighbors (KNN):
Use when localized patterns are significant, and the data is not too large.
· Naive Bayes:
Effective for text classification and situations where feature independence
assumption is reasonable.
