Cross-validation splits data into training and validation sets multiple times (e.g., k-fold), helping to assess model performance more reliably and reduce overfitting.

8. What is a confusion matrix? Explain its components.

Ans:

A confusion matrix evaluates classification models by showing:

TP (True Positive)
TN (True Negative)
FP (False Positive)
FN (False Negative)

9. How do you select important features in a dataset?

Ans:

Techniques include:

Filter methods (e.g., correlation)
Wrapper methods (e.g., recursive feature elimination)
Embedded methods (e.g., Lasso regularization)

10. Explain the working of the k-nearest neighbors (KNN) algorithm.

Ans:

KNN classifies a data point based on the 'k' closest neighbors in the training set. It uses distance metrics (like Euclidean) to find these neighbors and predicts the class based on majority vote (for classification) or average (for regression).
