     "config_version": "1.0.0",

     "training_burn": 1000,
   }

**config_version** The version of this config file.

**training_stopping_min_delta** The difference in log_likelihood values
used to determine whether the sample burning phase of Model training
should stop early

**training_stopping_n_samples** The number of samples to test for early
stopping of the sample burn phase of Model trainng. As each
log_likelihood value is generated, the early stopping algorithm finds
the min and max log_likelihood for this number of previous
log_likelihoods including the current sample. If the magnitude of the
difference between min and max is less than or equal to the
training_stopping_min_delta then the log_likelihood is said to have
converged, and sample burning is stopped.

**training_burn** The maximum number of samples to burn out during Model
Training. This value is used if the ‘DELPHI_N_SAMPLES’ environment
variable is not set.
