K-Means is sensitive to outliers as they can significantly affect the cluster centroids.

The ROC curve plots the true positive rate against the false positive rate, evaluating classification performance.

Imputation replaces missing data with estimated values, such as the mean or median.

A validation set is used to tune hyperparameters and select the best model configuration.

Decision Trees can be used for regression by predicting continuous values based on tree splits.

A confusion matrix shows the performance of a classification model by comparing predicted and actual labels.

Feature Selection chooses the most relevant features to improve model performance and reduce overfitting.

Reinforcement learning aims to maximize cumulative reward through trial-and-error interactions with an environment.

Both Bagging and Boosting are ensemble methods that combine multiple weak learners to improve accuracy.

The learning rate determines the step size for updating model parameters during gradient descent.
