Main take-away

Main take-away#


  • Hyperparameters have an impact on the models’ performance and should be wisely chosen;

  • The search for the best hyperparameters can be automated with a grid-search approach or a randomized search approach;

  • A grid-search is expensive and does not scale when the number of hyperparameters to optimize increase. Besides, the combination are sampled only on a regular grid.

  • A randomized-search allows a search with a fixed budget even with an increasing number of hyperparameters. Besides, the combination are sampled on a non-regular grid.
