Logistic Regression vs Linear Regression

📺 Logistic Regression vs. Linear Regression: Which One Should You Choose?

In this video, we delve into the differences between logistic regression and linear regression. Both are powerful tools in the field of machine learning, but they serve distinct purposes. Here’s what you’ll learn:

Linear Regression:
Linear regression is primarily used for predicting continuous numeric values (e.g., predicting house prices based on square footage).
It models the relationship between an independent variable (feature) and a dependent variable (target) using a straight line.
The goal is to find the best-fitting line that minimizes the sum of squared errors.
Logistic Regression:
Logistic regression, on the other hand, is designed for binary classification tasks (e.g., spam detection, disease diagnosis).
It estimates the probability of an event occurring (e.g., whether an email is spam or not).
The output is a probability score between 0 and 1, which can be thresholded to make predictions.
Key Differences:
Linear regression predicts continuous values, while logistic regression predicts probabilities.
Linear regression uses the least squares method, whereas logistic regression uses maximum likelihood estimation.
Linear regression assumes a linear relationship, while logistic regression models the log-odds.
When to Use Each:
Use linear regression when dealing with numeric outcomes and a linear relationship between variables.
Choose logistic regression when dealing with binary outcomes or probabilities.
