Description

Selection of the more accurate ANNs

After n-runs of the training service, the most accurate ANNs are selected based on goodness of validation errors. User is asked to set 3 parameters in the payload (defaults provided):

  1. mechanism (default percentile): the selection algorithm;
  2. threshold (default 95): the threshold;
  3. error (default nashSutcliffe): the error on which selecting the best ANNs.

Available selection algorithms

Following the list of available selection algorithm:

  1. percentile: select the ANNs that outperform with respect to a threshold error evaluated as a result of provided percentile from probability distribution of errors;
  2. number: select the best n-ANNs (n- is a user-provided number);
  3. error: select the best ANNs with respect to a user-provided threshold error.
