Machine learning models excel in classification, regression, anomaly detection, language translation, and more. Optimizing hyperparameters can enhance the performance of most machine learning models. 

This course will equip you with the skills to optimize hyperparameters for various machine learning models. You’ll begin with the introduction of hyperparameters and understand the need for optimizing them. Using a loan approval dataset for binary classification, you’ll explore both random and grid search methods for logistic regression and random forest models. Then, you’ll understand sequential model-based optimization (SMBO) and Tree-Structured Parzen Estimator (TPE), applying them to k-nearest neighbors (KNN) and histogram-based gradient boosting algorithms. You’ll finish by understanding and applying genetic algorithms to find the best hyperparameters for the KNN algorithm and random forest model.

After completing this course, you’ll have gained skills to master the hyperparameter optimization.
