ML Algorithm Deep-Dive Questions

Part of the Data Science Roadmap.

Summary

'Explain how random forests work' or 'when would you use logistic regression over a decision tree?' — testing genuine understanding of the algorithms from Phases 6-9, not just that you've called the library function.

How to Learn This

  • 1Review Phases 6-9 and practice explaining each major algorithm without notes.
  • 2Prepare to discuss trade-offs between algorithms for a given problem type.
  • 3Practice drawing a simple diagram (e.g. a decision tree split) while explaining out loud.
