Study Databricks ML-ASSOC Model Development: key concepts, common traps, and exam decision cues.
This is the heaviest technical domain on the exam. Databricks is testing whether you can build and judge models sensibly, not whether you can recite advanced theory without workflow context.
| Lesson | Focus |
|---|---|
| 3.1 Algorithm Choice, Estimators, Transformers and Pipelines | Learn how to choose algorithms and reason about pipeline components correctly. |
| 3.2 Hyperparameter Tuning, Search and Cross-Validation | Learn how Databricks tests tuning strategies, search methods, and model-count reasoning. |
| 3.3 Classification, Regression Metrics and Objective Fit | Learn how to pick metrics that match the scenario and interpret transformed targets correctly. |
| 3.4 Imbalance, Bias-Variance and Trustworthy Model Comparison | Learn how imbalance mitigation and bias-variance trade-offs affect model trustworthiness. |
