But sometimes the model learns the training data too well including the noise or errors. This is called overfitting and it makes the model perform badly on new data.<\/p>\n\n\n\n<p>To solve this problem we use a method called regularization. It helps control how much the model depends on each feature. Two common types of regularization are called Ridge and Lasso Regression.<\/p>\n\n\n\n<p>Ridge and Lasso Regression are better versions of <a href=\"https:\/\/www.iquanta.in\/blog\/linear-regression-explained-a-beginners-guide-with-python-code\/\">linear regression<\/a>. They add a penalty to the model to keep it simple and prevent overfitting. Ridge Regression makes all feature weights smaller but keeps them in the model. Lasso Regression can remove the unimportant ones by making their weights zero. In this blog you will learn about ridge and lasso regression in Python and see how to use them with examples.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><a

regression are techniques used to improve linear regression models by preventing overfitting. Ridge regression works by adding a penalty to the size of the coefficients, shrinking them towards zero but never exactly zero, which helps when factors are related. Lasso regression also adds a penalty but can shrink some coefficients exactly to zero, effectively selecting only the most important features. Both methods help create simpler, more reliable models that perform better on new data.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img decoding=\"async\" width=\"1024\" height=\"508\" src=\"https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/06\/image-6-1024x508.png\" alt=\"ridge and lasso regression\" class=\"wp-image-50815\" srcset=\"https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/06\/image-6-1024x508.png 1024w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/06\/image-6-300x149.png 300w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/06\/image-6-768x381.png 768w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/06\/image-6-846x420.png 846w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/06\/image-6-150x74.png 150w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/06\/image-6-696x345.png 696w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/06\/image-6-1068x530.png 1068w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/06\/image-6.png 1189w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure><\/div>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-understanding-regularization-in-machine-learning\"><span class=\"ez-toc-section\" id=\"Understanding_Regularization_in_Machine_learning\"><\/span><strong>Understanding Regularization in Machine learning<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Before we dive deeper into ridge and lasso regression in Python it&#8217;s important to understand what regularization means in <a href=\"https:\/\/www.iquanta.in\/blog\/what-is-machine-learning-an-introduction-for-beginners\/\">machine learning<\/a>.<\/p>\n\n\n\n<p>When we train a machine learning model our goal is to make it perform well not just on the training data but also on new data it has never seen before. However sometimes the model fits the training data too perfectly. It learns even the random noise or patterns that do not really matter. This is known as overfitting and it leads to poor performance on real-world data.<\/p>\n\n\n\n<p>Regularization helps fix this by adding a rule that keeps the model simple. It does this by reducing the size of the weights or coefficients in the model. Smaller weights usually mean the model is less sensitive to noise and more general in its predictions. Ridge and Lasso Regression are two regularization techniques that work by adding this extra rule to the model&#8217;s training process.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-ridge-regression-l2-regularization\"><span class=\"ez-toc-section\" id=\"What_is_Ridge_Regression_L2_Regularization\"><\/span><strong>What is Ridge Regression (L2 Regularization)?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Ridge Regression is a type of linear regression that uses something called L2 regularization. This means it adds a penalty to the model when the weights or coefficients become too large. The idea is to keep the model simple so it does not overfit the training data.<\/p>\n\n\n\n<p>In ridge regression we still try to find the best line or curve that fits the data. But while doing that we also make sure that the values of the coefficients stay small. This is done by adding the square of the coefficients to the loss function the model is trying to minimize.<\/p>\n\n\n\n<p>Ridge regression is helpful when we have many features and some of them are related to each other. Instead of removing features it keeps all of them and just reduces their impact. This makes ridge regression a good choice when we want to keep all our input variables but still control overfitting.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><a href=\"https:\/\/chat.whatsapp.com\/B6weknl7133BQXjPva0pgB\"><img decoding=\"async\" width=\"864\" height=\"129\" src=\"https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/06\/image-3.png\" alt=\"\" class=\"wp-image-50812\" srcset=\"https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/06\/image-3.png 864w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/06\/image-3-300x45.png 300w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/06\/image-3-768x115.png 768w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/06\/image-3-150x22.png 150w, https:\/\/www.iquanta.in\/blog\/wp-content\/uploads\/2025\/06\/image-3-696x104.png 696w\" sizes=\"(max-width: 864px) 100vw, 864px\" \/><\/a><\/figure><\/div>\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-is-lasso-regression-l1-regularization\"><span class=\"ez-toc-section\" id=\"What_is_Lasso_Regression_L1_Regularization\"><\/span><strong>What is Lasso Regression (L1 Regularization)?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Lasso Regression is another version of linear regression that uses L1 regularization. Just like ridge regression it tries to prevent overfitting by adding a penalty to the model. But the way it does this is a little different.<\/p>\n\n\n\n<p>In lasso regression the penalty is based on the absolute values of the coefficients instead of their squares. This small change makes a big difference. It allows lasso regression to make some of the coefficients exactly zero. This means it can completely remove some features from the model.<\/p>\n\n\n\n<p>Lasso regression is useful when we think that only a few features are important and the rest can be ignored. It helps us find the most useful features and build a simpler model. If we have a lot of input variables and we want to do feature selection then lasso regression is a good choice.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"

But sometimes the model learns the training data too well including the noise or errors. This is called overfitting and it makes the model perform badly on new data. To solve this problem we use a method called regularization.
