Compute the Pareto frontier between two objectives. For experiments with batch trials, a trial index or data object must be provided.

• outcome_constraints – Outcome constraints to be respected by the optimization. Can only contain constraints on metrics that are not primary or secondary objectives.

Find all Pareto points from an experiment.

Uses only values as observed in the data; no modeling is involved. Makes no assumption about the search space or types of parameters. If “data” is provided will use that, otherwise will use all data already attached to the experiment.

Uses all arms present in data; does not filter according to experiment search space. If arm_names is specified, will filter to just those arm whose names are given in the list.

Assumes experiment has a multiobjective optimization config from which the objectives and outcome constraints will be extracted.

Will generate a ParetoFrontierResults for every pair of metrics in the experiment’s multiobjective optimization config.

Parameters:

• experiment – The experiment.

• data – Data to use for computing Pareto frontier. If not provided, will lookup data from experiment.

• rel – Relativize results wrt experiment status quo. If None, then rel will be taken for each objective separately from its own objective threshold. rel must be specified if there are missing objective thresholds.

• arm_names – If provided, computes Pareto frontier only from among the provided list of arm names, plus status quo if set on experiment.

Returns: ParetoFrontierResults that can be used with interact_pareto_frontier.

Parameters:

• experiment – Experiment.

Returns: A torch modelbridge with transforms set.

ax.plot.pareto_utils.infer_reference_point_from_experiment(experiment: Experiment) → List[ObjectiveThreshold][source]¶

Aside from converting experiment to tensors, this wrapper transforms back and forth the objectives of the experiment so that they are appropriately used by infer_reference_point.

Parameters:

experiment – The experiment for which we want to infer the reference point.

Returns:

A list of objective thresholds representing the reference point.

Tile version of fitted outcome plots.

Parameters:

• model – model to use for predictions.

• generator_runs_dict – a mapping from generator run name to generator run.

• rel – if True, use relative effects. Default is True.

• show_arm_details_on_hover – if True, display parameterizations of arms on hover. Default is False.

• show_CI – if True, render confidence intervals.

• arm_noun – noun to use instead of “arm” (e.g. group)

• metrics – List of metric names to restrict to when plotting.

• fixed_features – Fixed features to use when making model predictions.

• data_selector – Function for selecting observations for plotting.

• scalarized_metric_config – An optional list of dicts specifying how to aggregate multiple metrics into a single scalarized metric. For each dict, the key is the name of the new scalarized metric, and the value is a dictionary mapping each metric to its weight. e.g. {“name”: “metric1:agg”, “weight”: {“metric1_c1”: 0.5, “metric1_c2”: 0.5}}.

• label_dict – A dictionary that maps the label to an alias to be used in the plot.

Tiled plot with all observed outcomes.

Will plot all observed arms. If data is provided will use that, otherwise will fetch data from experiment. Will plot all metrics in data unless a list is provided in metrics. If arm_names is provided will limit the plot to only arms in that list.

Parameters:

• experiment – Experiment

• data – Data to use, otherwise will fetch data from experiment.

• rel – Plot relative values, if experiment has status quo.

• metrics – Limit results to this set of metrics.

• arm_names – Limit results to this set of arms.

• arm_noun – Noun to use instead of “arm”.

• label_dict – A dictionary that maps the label to an alias to be used in the plot.

Returns: Plot config for the plot.

Slice Plot¶

Create interactive plot with predictions for a 1-d slice of the parameter space.

Parameters:

• model – ModelBridge that contains model for predictions

• generator_runs_dict – A dictionary {name: generator run} of generator runs whose arms will be plotted, if they lie in the slice.
