Randomized Parameter Search

../../../../_images/random_hyperparam.svg

Performs a randomized parameter search returning scores and best model found. Uses table as a “hypercube” of parameters to sample from. Ie. all combinations of parameters from all columns have equal chance of beeing sampled. Use masked values for parameter/columns with different lengths.

Configuration:
  • cv

    Number of fold in the default K-Fold cross validation. Ignored when cross-validation port is given

  • n_iter

    Number of randomized searches done
