Regression in Machine Learning

Regression analysis is a statistical technique used to establish a relationship between a dependent variable and one or more independent variables.

Types of Regression

Linear Regression: It highlights the relationship between the independent and dependent variables. Non-Linear Regression: It highlights relationship between the independent and dependent variables is not linear.

Uses of Regression Analysis

– Predicting future sales – Forecasting stock prices – Analyzing customer behavior – Identifying trends in data Recommending products to customers

The Regression Process

1. Data Collection 2. Data Exploration and Cleaning 3. Feature Engineering 4. Model Selection and Training 5. Model Evaluation

Common Regression Errors

Overfitting: This occurs when a regression model is too complex and fits the training data too closely, but does not perform well on unseen data. Underfitting: This occurs when a regression model is too simple and does not capture the underlying relationships in the data.

Tips for Improving Regression Performance

– Collect high-quality data – Clean your data – Explore your data – Select the right regression model – Train your model on a large dataset – Regularize your model – Evaluate your model
