Test your knowledge of API design essentials, including best practices around resources, data validation, versioning, and ensuring idempotency for robust model endpoints. This quiz helps you review the core principles needed for effective API development and management.

Sharpen your skills in evaluating machine learning models with this comprehensive quiz! You’ll explore key metrics such as accuracy, precision, recall, F1 score, ROC-AUC, confusion matrix, log loss, and mean squared error. Whether you’re working on classification or regression, this quiz will help you understand when and why to use each metric. Perfect for interview prep and improving your model assessment game.

Put your problem-solving to the test with this quiz focused on diagnosing underfitting and overfitting in machine learning models. Explore concepts like training vs validation error, bias-variance trade-off, model complexity, regularization techniques (L1/L2), cross-validation, and early stopping. Learn how to identify the symptoms and apply the right fix. Ideal for data scientists, ML engineers, and interview prep.

Sharpen your skills in evaluating classification models with this quiz on ROC curves and AUC (Area Under the Curve). You’ll explore true/false positive rates, threshold tuning, interpreting ROC shapes, comparing classifiers using AUC scores, and understanding when ROC vs Precision-Recall curves are more appropriate. Perfect for data scientists and ML interview prep.
