Regression: A Journey Towards Truth

📰 Medium · Machine Learning

Learn regression basics, loss functions, OLS, and gradient descent through intuitive explanations

intermediate Published 9 May 2026
Action Steps
  1. Apply linear regression to a sample dataset using scikit-learn to understand the concept of Ordinary Least Squares (OLS)
  2. Run gradient descent optimization algorithm on a regression model to minimize the loss function
  3. Configure and compare different loss functions, such as Mean Squared Error (MSE) and Mean Absolute Error (MAE), to evaluate their impact on regression models
  4. Test the performance of a regression model using metrics like R-squared and coefficient of determination
  5. Build a simple regression model from scratch using Python and NumPy to understand the underlying mathematics
