Hyperparameter Optimization
Hyperparameter optimization is the hunt for the settings (learning rate, depth, regularization) that a model does not learn by itself, done through grid, random, or Bayesian search. AI, ML, and GenAI engineer interviews probe it because what separates candidates is usually method choice and budget discipline: understanding why random search beats grid in high dimensions, how successive halving pours compute into promising configs, and how to run the search without quietly leaking the test set into your model selection.
