- create_experiment_data_collection_from_unique_parameters(experiment_data: piel.types.experimental.ExperimentData) piel.types.experimental.ExperimentDataCollection[source]#
Each individual raw
ExperimentDatacan contain multiple operating points or unique parameters which are being tested. It can be handy to create subsets ofExperimentData-> multipleExperimentData``s that correspond to relevant operating points stored with the relevant parameters both internally and in an ``ExperimentDataCollection. As such, it is easier to understand the collection of data measurements based on this and perform plotting accordingly in a more relevant implementation. Likewise, the corresponding operating point metadata is encoded in the generatedExperimentDatasets.First, we will need to extract the operating points from the
ExperimentData.experiment.parameters. This can be done by identifying the unique elements from the pandas DataFrame. Then, we will need to create a newExperimentDatafor each of the operating points. Finally, we will need to create a newExperimentDataCollectionwith the newExperimentData.
- experiment_data_from_parameter_subset(experiment_data: piel.types.ExperimentData, subset: pandas.DataFrame) piel.types.ExperimentData[source]#
Filters the given ExperimentData based on a subset of parameters.
- Parameters:
experiment_data (ExperimentData) – The original experiment data.
subset (pd.DataFrame) – The subset of parameters to filter by.
- Returns:
A new ExperimentData instance containing only the filtered data.
- Return type:
- compose_xarray_dataset_from_experiment_data(experiment_data: piel.types.ExperimentData)[source]#
Composes an xarray.Dataset from an ExperimentData instance, using all experiment parameters as coordinates.
- Parameters:
experiment_data (ExperimentData) – The experiment data containing parameters and measurements.
- Returns:
An xarray Dataset containing the measurements indexed by all parameters and metric name.
- Return type:
xr.Dataset
- Raises:
ValueError – If the number of parameters does not match the number of measurement data entries.
AttributeError – If any measurement data entry lacks the measurements attribute.
- construct_experiment_directories(experiment: piel.types.experimental.Experiment, parent_directory: piel.types.PathTypes, construct_directory: bool = True, write_schema_markdown: bool = False) piel.types.PathTypes[source]#
This function constructs the directories of the experiment configuration. It iterates through the experiment instances. It checks that each of these instances is unique. Each experiment.experiment_instance should have a unique name. This directory name is an enumerated integer. This enumerated integer is the index of the experiment instance in the experiment.experiment_instances tuple. This function should be able to create a new experiment configuration from scratch.
A parent directory is defined in which to create the experiment directories. The experiment directory is created in the parent directory. The experiment directory contains the experiment.json file. The experiment.json file contains the experiment configuration. Note that the experiment.json file should be recursive. The experiment directory also contains the experiment instances. The experiment instances are directories. Each experiment instance directory contains the instance.json file. The instance.json file contains the experiment instance configuration. This is as flat as the directory structure gets.
- The instance directory will contain the data files alongside all of this metadata information.
The data files are at the top level of the instance directory, and should not have subdirectories.
The data files are manually generated from the corresponding measurements specified in the instance.json file. These will be added after wards from this directory structure creation.
This schema is used to generate a README file for the experiment configuration if write_markdown_schema is true. This README file should contain all the information about the experiment configuration. This includes the experiment instances and their corresponding configurations.
- Parameters:
experiment (Experiment) – The experiment configuration to create the directories for.
parent_directory (PathTypes) – The parent directory to create the experiment directory in.
write_markdown_schema (bool) – Writes the json schema into markdown if true. Defaults to false.
- Returns:
The path to the experiment directory.
- Return type:
PathTypes
