It works by recursively partitioning the data to make predictions based on input features.<\/p><h4><span style=\"color: #000000;\">8. <strong>What is the Central Limit Theorem?<\/strong><\/span><\/h4><p>The Central Limit Theorem states that the distribution of sample means approximates a normal distribution as the sample size increases, regardless of the original distribution.<\/p><h4><span style=\"color: #000000;\">9. <strong>What is the purpose of regularization in machine learning?<\/strong><\/span><\/h4><p>Regularization techniques, such as L1 and L2, are used to prevent overfitting by penalizing large coefficients in the model, thereby simplifying the model.<\/p><h4><span style=\"color: #000000;\">10. <strong>What is A\/B testing?<\/strong><\/span><\/h4><p>A\/B testing is a statistical method used to compare two versions of a webpage or product to determine which one performs better in terms of a specified metric.<\/p><\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-244dea06 e-flex e-con-boxed e-con e-parent\" data-id=\"244dea06\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t<div class=\"elementor-element elementor-element-4ec730c5 e-con-full e-flex e-con e-child\" data-id=\"4ec730c5\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-1a55beab elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"1a55beab\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p><strong>Ready to take you Data Science and Machine Learning skills to the next level?
