[In Depth] Linear Regression: Concept And Application

Imagine you are a real estate agent trying to estimate the price of a house based on its size. You’ve probably noticed that larger houses tend to have higher prices, but how can you quantify this relationship? This is where linear regression, a fundamental concept in machine learning, comes into play.

Linear regression is a powerful tool that helps us understand and predict the relationship between two variables. In our real estate example, the size of the house is the independent variable (also known as the predictor or feature), and the price is the dependent variable (the target or outcome). Linear regression aims to find the best-fitting line through the data points that can be used to make predictions.

To delve into the world of linear regression and how we use linear regression in machine learning, it’s essential to understand the core concepts involved.

Linear regression is a stepping stone for more advanced machine learning techniques and is widely employed in diverse fields such as finance, healthcare, and marketing. So, let’s embark on this journey to unravel the mysteries of linear regression and discover how it can be a valuable asset in your machine-learning toolkit.
