What's a best practice for Hyperopt workflow?

  • Choose what hyperparameters are reasonable to optimize
  • Define broad ranges for each of the hyperparameters (including the default where applicable)
  • Run a small number of trials
  • Observe the results in an MLflow parallel coordinate plot and select the runs with lowest loss
  • Move the range towards those higher/lower values when the best runs’ hyperparameter values are pushed against one end of a range
  • Determine whether certain hyperparameter values cause fitting to take a long time (and avoid those values)
  • Re-run with more trials
  • Repeat until the best runs are comfortably within the given search bounds and none are taking excessive time
