ResidualHistogram
Distribution of the residuals, with the zero line marked.
Shows the shape of the error rather than its magnitude. Residuals should centre on zero and fall away symmetrically; a shifted centre means constant bias, a long tail on one side means the model fails asymmetrically, and two peaks usually mean a subpopulation the model treats as one group.
Parameters
- bins : integer, default=
30 - Number of bins used to bucket the residuals.
Methods
compute(self, y_true, y_pred, class_names: Optional[List[str]] = None) -> List[DashAI.back.core.artifacts.Artifact]
ResidualHistogramBuild the residual histogram.
Parameters
- y_true : ndarray
- Ground truth values.
- y_pred : ndarray
- Model predictions.
- class_names : Optional[List[str]]
- Unused; always None for regression.
Returns
- List[Artifact]
- A single histogram figure with a zero reference line.
get_credential(self, name: str)
ConfigObjectResolve a registered credential component by name.
Parameters
- name : str
- Credential component class name (e.g. "HuggingFaceCredential").
Returns
- BaseCredential
- An instance of the requested credential component.
get_metadata(cls) -> Dict[str, Any]
BaseReportGet metadata values for the current report.
Returns
- Dict[str, Any]
- UI metadata, including whether the report needs a model that outputs class probabilities.
get_schema(cls) -> dict
ConfigObjectGenerates the component related Json Schema.
Returns
- dict
- Dictionary representing the Json Schema of the component.
validate_and_transform(self, raw_data: dict) -> dict
ConfigObjectIt takes the data given by the user to initialize the model and returns it with all the objects that the model needs to work.
Parameters
- raw_data : dict
- A dictionary with the data provided by the user to initialize the model.
Returns
- dict
- A validated dictionary with the necessary objects.
