  • keep_in_memory (bool) — keep all predictions and references in memory. Not possible in distributed settings.
  • cache_dir (str) — Path to a directory in which temporary prediction/references data will be stored. The data directory should be located on a shared file-system in distributed setups.
  • num_process (int) — specify the total number of nodes in a distributed settings. This is useful to compute module in distributed setups (in particular non-additive modules like F1).
  • process_id (int) — specify the id of the current process in a distributed setup (between 0 and num_process-1) This is useful to compute module in distributed setups (in particular non-additive metrics like F1).
  • seed (int, optional) — If specified, this will temporarily set numpy’s random seed when evaluate.EvaluationModule.compute() is run.
  • experiment_id (str) — A specific experiment id. This is used if several distributed evaluations share the same file system. This is useful to compute module in distributed setups (in particular non-additive metrics like F1).

CombinedEvaluations

The combine function allows to combine multiple EvaluationModules into a single CombinedEvaluations.

evaluate.combine

< >

( evaluations force_prefix = False )

Parameters

  • evaluations (Union[list, dict]) — A list or dictionary of evaluation modules. The modules can either be passed as strings or loaded EvaluationModules. If a dictionary is passed its keys are the names used and the values the modules. The names are used as prefix in case there are name overlaps in the returned results of each module or if force_prefix=True.
  • force_prefix (bool, optional, defaults to False) — If True all scores from the modules are prefixed with their name. If a dictionary is passed the keys are used as name otherwise the module’s name.

Combines several metrics, comparisons, or measurements into a single CombinedEvaluations object that can be used like a single evaluation module.

If two scores have the same name, then they are prefixed with their module names. And if two modules have the same name, please use a dictionary to give them different names, otherwise an integer id is appended to the prefix.

Examples:

clf_metrics = combine([“accuracy”, “f1”, “precision”,“recall”]) clf_metrics.compute(predictions=[0,1], references=[1,1]) {‘accuracy’: 0.5, ‘f1’: 0.66, ‘precision’: 1.0, ‘recall’: 0.5}
