In this segment, we cover model training, a phase where many candidates fall into autopilot. To stand out, we need to show thoughtfulness, adaptability, and a clear connection between our choices and the problem at hand.
- Mediocre performance involves picking a default model (e.g., logistic regression or random forest), using out-of-the-box settings with no tuning or justification.
- Strong candidates choose models deliberately, explaining how their selection fits the data characteristics, business goals, or system constraints.
- We improve performance through hyperparameter tuning, using techniques like grid search or informed manual adjustments based on EDA insights.
- When appropriate, we apply ensemble methods (e.g., boosting, bagging, stacking) to push performance further.
- Most importantly, we demonstrate that our modeling choices are intentional and grounded in context, not just rote or random experimentation.
