Machine Learning Interview Questions 2023

<p>As per my recent Interview experience I have created a list of questions on various Machine Learning Sections. This list will comprise of just questions, I am planning to write a separate blog post for all the answers.</p> <p><img alt="" src="https://miro.medium.com/v2/resize:fit:700/1*BGWGCso-clnNF8jPHSUnkQ.jpeg" style="height:461px; width:700px" /></p> <h1>Machine Learning Interview Questions</h1> <ol> <li>What is Regression?</li> <li>What are the Types of regression?</li> <li>Explain the assumptions of Linear regression.</li> <li>How to evaluate regression models?</li> <li>Explain different types of model Testing methods.</li> <li>Explain Benefits of cross validation?</li> <li>What is overfitting?</li> <li>What are different ways to fix overfitting?</li> <li>How to handle imbalanced data in a dataset?</li> <li>What to do if your data is skewed?</li> <li>What if your data has outliers, how to identify and different ways to fix?</li> <li>What is difference between lasso and ridge regression?</li> <li>What is cross entropy?</li> <li>Difference between precision and recall?</li> <li>What is a confusion matrix?</li> <li>What is AUC?</li> <li>What is bias variance trade-off?</li> <li>What is correlation?
