ForecastModel

Top-level pipeline orchestrator. See Pipeline Walkthrough for full examples.

Constructor

ForecastModel(
    station: str,
    channel: str,
    network: str,
    location: str = "",
    day_to_forecast: int = 2,
    output_dir: str | None = None,
    root_dir: str | None = None,
    overwrite: bool = False,
    n_jobs: int = 1,
    verbose: bool = False,
)

Param	Type	Default	Notes
station	str	-	Station code (uppercased)
channel	str	-	Channel code (uppercased)
network	str	-	FDSN network code
location	str	""	FDSN location code
day_to_forecast	int	2	Look-ahead window in days; threaded into TrainingModel/PredictionModel as window_size
output_dir	str | None	None	Defaults to {cwd}/output (or {root_dir}/output when root_dir set)
root_dir	str | None	None	Anchor for relative output_dir
overwrite	bool	False	Default for stage methods
n_jobs	int	1	Default for stage methods; clamped to cpu_count - 2
verbose	bool	False	Default for stage methods

calculate(...)

fm.calculate(
    start_date: str | datetime,
    end_date: str | datetime,
    source: Literal["sds", "fdsn"] = "sds",
    methods: str | list[str] | None = None,
    remove_outlier_method: Literal["all", "maximum"] = "maximum",
    remove_tremor_anomalies: bool = False,
    interpolate: bool = True,
    value_multiplier: float | None = None,
    cleanup_daily_dir: bool = False,
    plot_daily: bool = False,
    save_plot: bool = False,
    plot_overwrite: bool = False,
    sds_dir: str | None = None,
    client_url: str = "https://service.iris.edu",
    minimum_completion_ratio: float = 0.3,
    overwrite: bool | None = None,
    n_jobs: int | None = None,
    verbose: bool | None = None,
) -> Self

start_date is internally pushed back by day_to_forecast days for full lead-in coverage. sds_dir is required when source="sds". None for overwrite/n_jobs/verbose means "inherit from constructor". Sets self.CalculateTremor, self.tremor_df, self.tremor_start_date, self.tremor_end_date.

train(...)

fm.train(
    start_date: str | datetime,
    end_date: str | datetime,
    eruption_dates: list[str],
    window_step: int,
    window_step_unit: Literal["minutes", "hours"],
    label_builder: Literal["standard", "dynamic"] = "standard",
    days_before_eruption: int | None = None,
    classifiers: str | list[str] = "rf",
    cv_strategy: Literal["shuffle", "stratified", "shuffle-stratified"] = "shuffle-stratified",
    cv_splits: int = 5,
    scoring: str = "balanced_accuracy",
    top_n_features: int = 20,
    include_eruption_date: bool = True,
    select_tremor_columns: list[str] | None = None,
    save_tremor_matrix_per_method: bool = True,
    exclude_features: list[str] | None = None,
    select_features: str | list[str] | None = None,
    minimum_completion: float = 1.0,
    seeds: int = 10,
    resample_method: Literal["under", "over", "auto"] | None = "auto",
    minority_threshold: float = 0.15,
    sampling_strategy: str | float = 0.75,
    plot_features: bool = True,
    output_dir: str | None = None,
    overwrite: bool | None = None,
    n_jobs: int | None = None,
    n_grids: int = 1,
    use_cache: bool = True,
    verbose: bool | None = None,
) -> Self

Requires calculate() to have populated tremor data first. label_builder="dynamic" requires days_before_eruption. use_cache=True short-circuits via TrainingModel.load(training_dir, identity) when the cache identity matches. Sets self.TrainingModel, self.ClassifierEnsemble, and self._training_cache_hash.

predict(...)

fm.predict(
    start_date: str | datetime,
    end_date: str | datetime,
    window_step: int,
    window_step_unit: Literal["minutes", "hours"],
    save_seed_result: bool = True,
    plot_threshold: float = 0.5,
    plot_title: str | None = None,
    plot_pdf: bool = True,
    output_dir: str | None = None,
    overwrite: bool | None = None,
    n_jobs: int | None = None,
    use_cache: bool = True,
    verbose: bool | None = None,
    **plot_kwargs: Any,
) -> Self

Requires train() first. **plot_kwargs is forwarded to plot_forecast (see Visualization for keys) and is not captured in ForecastConfig because matplotlib objects do not round-trip through YAML. Sets self.PredictionModel, self.results.

evaluate(...)

fm.evaluate(
    model: Literal["training", "prediction"] = "prediction",
    eruption_dates: list[str] | None = None,
    plot_per_seed: bool = False,
    plot_aggregate: bool = True,
    output_dir: str | None = None,
    overwrite: bool | None = None,
    n_jobs: int | None = None,
    verbose: bool | None = None,
) -> Self

eruption_dates=None falls back to the dates captured during train(). Always auto-calls save_config() at the end. Sets self.EvaluationModel, self.evaluation_results.

explain(...)

fm.explain(
    model: Literal["training", "prediction"] = "prediction",
    eruption_dates: list[str] | None = None,
    save_per_seed: bool = True,
    plot_per_seed: bool = True,
    figsize: tuple[float, float] | None = None,
    max_display: int = 20,
    group_remaining_features: bool = False,
    dpi: int = 150,
    check_additivity: bool = False,
    overwrite_classifier_explanation: bool = False,
    output_dir: str | None = None,
    overwrite: bool | None = None,
    n_jobs: int | None = None,
    verbose: bool | None = None,
) -> Self

Requires the upstream TrainingModel or PredictionModel to exist on self (run train() and, for model="prediction", predict() first). eruption_dates=None falls back to the dates captured during train(). Internally constructs an ExplanationModel, runs explain() then plot(), and sets self.ExplanationModel. See Explanation Workflow for the TreeExplainer constraint (RF / lite-rf / GB / XGB only — other classifiers are skipped with a warning).

Config round-trip

Method	Returns	Notes
fm.save_config(path=None, fmt="yaml")	str	Defaults to {station_dir}/forecast.config.{yaml,json}
ForecastModel.from_config(path)	ForecastModel	Classmethod; restores the captured ForecastConfig
fm.run()	Self	Idempotent replay of every captured non-None stage

---

TrainingModel

BaseModel subclass with content-addressable cache participation. Use standalone when running outside ForecastModel; otherwise fm.train(...) constructs it for you.

Constructor

TrainingModel(
    tremor_data: str | pd.DataFrame,
    start_date: str | datetime,
    end_date: str | datetime,
    classifiers: str | list[str],
    eruption_dates: list[str],
    window_size: int = 2,
    cv_strategy: Literal["shuffle", "stratified", "shuffle-stratified"] = "shuffle-stratified",
    cv_splits: int = 5,
    top_n_features: int = 20,
    include_eruption_date: bool = False,
    output_dir: str | None = None,
    root_dir: str | None = None,
    overwrite: bool = False,
    n_jobs: int = 1,
    n_grids: int = 1,
    verbose: bool = False,
)

Pipeline methods (all return Self)

tm.build_label(
    window_step: int,
    window_step_unit: Literal["minutes", "hours"],
    builder: Literal["standard", "dynamic"] = "standard",
    days_before_eruption: int | None = None,
    verbose: bool | None = None,
)

tm.extract_features(
    select_tremor_columns: list[str] | None = None,
    save_tremor_matrix_per_method: bool = False,
    exclude_features: list[str] | None = None,
    select_features: str | list[str] | None = None,
    save_tremor_matrix_per_id: bool = False,
    minimum_completion: float = 1.0,
    overwrite: bool = False,
    n_jobs: int | None = None,
    verbose: bool | None = None,
)

tm.fit(
    seeds: int = 25,
    resample_method: Literal["under", "over", "auto"] | None = "auto",
    minority_threshold: float = 0.15,
    sampling_strategy: str | float = 0.75,
    plot_features: bool = False,
    scoring: str = "balanced_accuracy",
    compute_learning_curve: bool = False,
)

Cache + persistence

Method	Notes
TrainingModel.build_identity(**kwargs)	Classmethod; returns canonical identity dict for hashing. Called both by ForecastModel.train() (before the instance exists, for cache lookup) and inside fit() (with kwargs pulled from self, for the save).
tm.save(identity)	Cache mode: writes {training_dir}/{hash}.TrainingModel.pkl + .params.json sidecar
tm.save()	Legacy mode (no identity): {output_dir}/TrainingModel_{basename}.pkl joblib dump
TrainingModel.load(stage_dir, identity)	Classmethod; returns the instance on cache hit or None
tm.save_config(path=None, fmt="yaml")	{training_dir}/training.config.{yaml,json} — auto-called at end of fit()

Populated attributes after fit(): tm.results (per-classifier trained-model JSON registry paths written by save_model_json), tm.ClassifierEnsemble, tm.classifier_ensemble_path, tm.features_df, tm.labels.

---

PredictionModel

BaseModel subclass with content-addressable cache participation.

Constructor

PredictionModel(
    model: str | ClassifierEnsemble | SeedEnsemble,
    tremor_data: str | pd.DataFrame,
    start_date: str | datetime,
    end_date: str | datetime,
    window_size: int = 2,
    overwrite: bool = False,
    output_dir: str | None = None,
    root_dir: str | None = None,
    n_jobs: int = 1,
    verbose: bool = False,
)

model accepts a live ClassifierEnsemble / SeedEnsemble, a ClassifierEnsemble.json / .pkl, a SeedEnsemble_*.pkl, or a trained-model registry .csv - resolved via ClassifierEnsemble.from_any(...).

Pipeline methods

pm.build_label(
    window_step: int,
    window_step_unit: Literal["minutes", "hours"],
) -> Self

pm.extract_features(
    select_tremor_columns: list[str] | None = None,
    save_tremor_matrix_per_method: bool = False,
    exclude_features: list[str] | None = None,
    overwrite: bool = False,
    n_jobs: int | None = None,
    verbose: bool | None = None,
) -> Self

pm.forecast(
    save_seed_result: bool = True,
    plot_threshold: float = 0.5,
    plot_title: str | None = None,
    plot_pdf: bool = True,
    **plot_kwargs,
) -> pd.DataFrame

forecast() returns the results DataFrame indexed by datetime with one column per {classifier}_{eruption_probability|uncertainty|confidence|prediction} plus the four consensus_* columns. Also sets pm.results and pm.forecast_plot_path.

Cache + persistence

Same surface as TrainingModel: build_identity(**kwargs), save(identity), load(stage_dir, identity). The cache identity embeds the upstream training_hash (constructor param).

Method	Notes
pm.save_config(path=None, fmt="yaml")	{prediction_dir}/prediction.config.{yaml,json} — auto-called at end of forecast()

PredictionConfig captures the user-supplied model and tremor_data as string handles (null when a live in-memory object was passed).

---

EvaluationModel

BaseModel subclass (no cache).

Constructor

EvaluationModel(
    model: TrainingModel | PredictionModel,
    eruption_dates: list[str] | None = None,
    overwrite: bool = False,
    output_dir: str | None = None,
    root_dir: str | None = None,
    n_jobs: int = 1,
    verbose: bool = False,
)

Raises ValueError if model is a PredictionModel and eruption_dates is None, or if model.ClassifierEnsemble is None. Output is namespaced to evaluation/{model.kind}/.

Methods

em.evaluate(
    plot_aggregate: bool = True,
    plot_per_seed: bool = False,
    plot_shap: bool = False,
    compare_classifiers: bool = True,
) -> dict[str, pd.DataFrame]

em.compare(
    metrics: str | list[str] | None = None,
) -> ClassifierComparator

EvaluationModel.from_file(
    filepath: str,
    eruption_dates: list[str] | None = None,
    overwrite: bool = False,
    output_dir: str | None = None,
    root_dir: str | None = None,
    n_jobs: int = 1,
    verbose: bool = False,
) -> EvaluationModel

Classmethod. Loads a .pkl produced by TrainingModel.save() or PredictionModel.save() and dispatches on kind.

plot_shap=True is reserved on this surface and emits a warning — SHAP rendering is produced by the dedicated Explanation Workflow via ExplanationModel.explain(). plot_per_seed=True is plumbed through to MetricsEnsemble.plot_seed() for the metric plots (ROC, PR, confusion, etc.) — it does not render SHAP.

Method	Notes
em.save_config(path=None, fmt="yaml")	{evaluation_dir}/evaluation.config.{yaml,json} — auto-called at end of evaluate()

EvaluationConfig omits the upstream model parameter (live model instances are not serializable). Captured fields: eruption_dates, overwrite, output_dir, root_dir, n_jobs, verbose.

---

ExplanationModel

BaseModel subclass with content-addressable cache participation. Per-seed SHAP explanations over a fitted ClassifierEnsemble — never re-fits. See Explanation Workflow.

Constructor

ExplanationModel(
    model: TrainingModel | PredictionModel,
    eruption_dates: list[str] | None = None,
    overwrite: bool = False,
    output_dir: str | None = None,
    root_dir: str | None = None,
    n_jobs: int = 1,
    verbose: bool = False,
)

Output is namespaced to explanation/{model.kind}/. The constructor sets self.kind="explanation", self.model_kind (mirrored from the upstream TrainingModel.kind / PredictionModel.kind), self.ClassifierEnsemble, self.features_df, self.explanation_dir, self.classifiers_dir, and self.ExplainerEnsemble.

Methods

em.explain(
    save_per_seed: bool = True,
    check_additivity: bool = False,
    overwrite_classifier_explanation: bool = False,
) -> Self

em.plot(
    figsize: tuple[float, float] | None = None,
    max_display: int = 20,
    group_remaining_features: bool = False,
    dpi: int = 150,
    plot_per_seed: bool = True,
)

explain() delegates to ExplainerEnsemble.explain() and caches the result via BaseModel.save(identity). On a cache hit the stored self.explanations is restored without re-running SHAP. plot() renders the per-eruption waterfall (only when eruption_dates is available) and, optionally, per-seed bar + beeswarm plots.

ExplanationModel.from_file(
    filepath: str,
    eruption_dates: list[str] | None = None,
    overwrite: bool = False,
    output_dir: str | None = None,
    root_dir: str | None = None,
    n_jobs: int = 1,
    verbose: bool = False,
) -> ExplanationModel

Classmethod. Loads a .pkl from TrainingModel.save() or PredictionModel.save() and constructs an ExplanationModel against it. Raises TypeError if the pickle holds anything else.

Populated attributes after explain(): em.explanations: list[ClassifierExplanation].

Method	Notes
em.save_config(path=None, fmt="yaml")	{explanation_dir}/explanation.config.{yaml,json} — auto-called at end of explain()

ExplanationConfig omits the upstream model parameter (live model instances are not serializable). Captured fields: eruption_dates, overwrite, output_dir, root_dir, n_jobs, verbose.

---

ExplainerEnsemble

ExplainerEnsemble(
    classifier_ensemble: ClassifierEnsemble,
    features_df: pd.DataFrame,
    kind: Literal["training", "prediction"] = "prediction",
    output_dir: str | None = None,
    explanation_dir: str | None = None,
    root_dir: str | None = None,
    overwrite: bool = False,
    n_jobs: int = 1,
    verbose: bool = False,
)

Per-seed SHAP engine driven by shap.TreeExplainer. Non-tree classifiers (svm, lr, nn, dt, knn, nb, voting) are skipped at the per-classifier loop with a warning. explanation_dir is the sibling-of-classifiers/ root used for per-eruption waterfall plots; when omitted it falls back to dirname(output_dir).

Methods

ee.explain(
    save_per_seed: bool = True,
    check_additivity: bool = False,
    overwrite_classifier_explanation: bool = False,
) -> Self

ee.plot_seed(
    max_display: int = 20,
    group_remaining_features: bool = False,
    dpi: int = 150,
)   # per-classifier bar + beeswarm under classifiers/{ClfName}/figures/

ee.plot_waterfall(
    labels: pd.Series | pd.DataFrame,
    eruption_dates: list[str],
    figsize: tuple[float, float] | None = None,
    max_display: int = 20,
    dpi: int = 150,
)   # per-eruption waterfall under {explanation_dir}/eruptions/{date}/

Static helpers

ExplainerEnsemble.explain_seed(
    seed: dict,
    features_df: pd.DataFrame,
    save_per_seed: bool = False,
    check_additivity: bool = False,
    seed_explanation_filepath: str | None = None,
) -> shap.Explanation

ExplainerEnsemble.explain_classifier(
    seed_ensemble: SeedEnsemble,
    features_df: pd.DataFrame,
    save_per_seed: bool = False,
    kind: Literal["training", "prediction"] = "prediction",
    check_additivity: bool = False,
    output_dir: str | None = None,
    overwrite: bool = False,
    verbose: bool = False,
) -> ClassifierExplanation

ExplainerEnsemble.normalise_shap_values(
    explanation: shap.Explanation,
) -> tuple[np.ndarray, np.ndarray]

Imported from eruption_forecast.ensemble.explainer_ensemble (intentionally not re-exported from ensemble/__init__.py to keep that subpackage cycle-free).

---

SeedExplanation / ClassifierExplanation

@dataclass(frozen=True, slots=True)
class SeedExplanation:
    random_state: int
    shap_values: shap.Explanation

@dataclass(slots=True)
class ClassifierExplanation:
    classifier_name: str
    seeds: list[SeedExplanation] = field(default_factory=list)

Both re-exported from eruption_forecast.dataclass. SeedExplanation is frozen; ClassifierExplanation is mutable so ExplainerEnsemble.explain_classifier() can append seeds incrementally. Produced by the explanation stage and consumed by every plot helper in plots/explanation_plots.py.

---

CalculateTremor

Constructor

CalculateTremor(
    start_date: str | datetime,
    end_date: str | datetime,
    station: str,
    channel: str,
    network: str,
    location: str | None = None,
    channel_type: str = "D",
    methods: list[str] | None = None,
    output_dir: str | None = None,
    root_dir: str | None = None,
    overwrite: bool = False,
    remove_outlier_method: Literal["all", "maximum"] = "maximum",
    remove_tremor_anomalies: bool = False,
    interpolate: bool = False,
    value_multiplier: float | None = None,
    cleanup_daily_dir: bool = False,
    plot_daily: bool = False,
    save_plot: bool = False,
    plot_overwrite: bool = False,
    filename_prefix: str | None = None,
    minimum_completion_ratio: float = 0.3,
    n_jobs: int = 1,
    verbose: bool = False,
    debug: bool = False,
)

Source binding + execution (all return Self)

ct.from_sds(sds_dir: str)
ct.from_fdsn(client_url: str | None = None)
ct.change_freq_bands(freq_bands: list[tuple[float, float]])
ct.run()

After run(): ct.df (the tremor DataFrame), ct.csv (path to the merged file), ct.daily_files, ct.daily_dir.

---

LabelBuilder / DynamicLabelBuilder

LabelBuilder(
    start_date: str | datetime,
    end_date: str | datetime,
    window_step: int,
    window_step_unit: Literal["minutes", "hours"],
    day_to_forecast: int,
    eruption_dates: list[str] | list[datetime],
    volcano_id: str | None = None,
    include_eruption_date: bool = True,
    output_dir: str | None = None,
    root_dir: str | None = None,
    verbose: bool = False,
    debug: bool = False,
)

DynamicLabelBuilder(
    days_before_eruption: int,
    window_step: int,
    window_step_unit: Literal["minutes", "hours"],
    day_to_forecast: int,
    eruption_dates: list[str],
    volcano_id: str | None = None,
    output_dir: str | None = None,
    root_dir: str | None = None,
    prefix_filename: str | None = None,
    verbose: bool = False,
    debug: bool = False,
)

Both expose .build() -> Self. After build(): lb.df (DateTime-indexed id/is_erupted frame), lb.csv (path to the label CSV).

Note that within TrainingModel, include_eruption_date defaults to False (training pipeline behaviour); the LabelBuilder constructor's own default is True. The difference is intentional - see Training Workflow.

---

FeaturesBuilder

FeaturesBuilder(
    tremor_matrix_df: pd.DataFrame,
    output_dir: str | None = None,
    label_df: pd.DataFrame | None = None,
    select_features: list[str] | None = None,
    root_dir: str | None = None,
    overwrite: bool = False,
    n_jobs: int = 1,
    verbose: bool = False,
)

fb.extract_features(
    select_tremor_columns: list[str] | None = None,
    exclude_features: list[str] | None = None,
) -> pd.DataFrame

label_df=None switches the builder to prediction mode (no tsfresh relevance filtering). select_features pre-filters tsfresh to the supplied fully-qualified feature names.

---

TremorMatrixBuilder

TremorMatrixBuilder(
    tremor_df: pd.DataFrame,
    label_df: pd.DataFrame,
    output_dir: str | None = None,
    window_size: int = 1,
    root_dir: str | None = None,
    minimum_completion: float = 1.0,
    overwrite: bool = False,
    verbose: bool = False,
)

tmb.build(
    select_tremor_columns: list[str] | None = None,
    save_tremor_matrix_per_method: bool = False,
    save_tremor_matrix_per_id: bool = False,
) -> Self

After build(): tmb.df is the matrix with id, datetime, and tremor columns.

---

FeatureSelector

FeatureSelector(
    method: Literal["tsfresh", "random_forest"] = "tsfresh",
    random_state: int = 42,
    output_dir: str | None = None,
    n_jobs: int = 1,
    verbose: bool = False,
)

Used internally by TrainingModel.fit() per-seed (hardcoded method="tsfresh"); surfaced publicly for ad-hoc selection experiments. Pick method="tsfresh" for FDR-controlled p-value filtering (fast, model-agnostic) or method="random_forest" for permutation importance from a RandomForest probe. Populated after fit(X, y): selected_features_, p_values_, importance_scores_, n_features_tsfresh, n_features_rf, n_features, feature_names_.

SeedEnsemble

class SeedEnsemble(BaseEnsemble, BaseEstimator, ClassifierMixin):
    classifier_name: str
    seeds: list[dict]

Construction

SeedEnsemble(classifier_name: str)

# Recommended: dispatch on file extension (.json or .csv).
SeedEnsemble.from_any(
    trained_model_path: str,
    classifier_name: str | None = None,
    verbose: bool = False,
) -> SeedEnsemble

# New JSON trained-model registry written by utils.ml.save_model_json.
SeedEnsemble.from_json(
    trained_model_json: str,
    classifier_name: str | None = None,
    verbose: bool = False,
) -> SeedEnsemble

# Legacy CSV registry loader (kept for backwards compatibility).
SeedEnsemble.from_registry(
    registry_csv: str,
    classifier_name: str | None = None,
    verbose: bool = False,
) -> SeedEnsemble

Inference

se.predict_proba(X: pd.DataFrame) -> np.ndarray   # (n_samples, 2)

se.predict_with_uncertainty(
    X: pd.DataFrame,
    threshold: float = 0.5,
) -> tuple[np.ndarray, np.ndarray, np.ndarray, np.ndarray]
# returns (mean_proba, std_proba, confidence, prediction)

save(path) / load(path) inherited from BaseEnsemble.

ClassifierEnsemble

class ClassifierEnsemble(BaseEnsemble, BaseEstimator, ClassifierMixin)

Construction (classmethods)

Factory	Accepts
from_any(source, verbose=False)	ClassifierEnsemble.{json,pkl}, SeedEnsemble_*.pkl, trained-model registry .json (list) or .csv, or a live SeedEnsemble
from_seed_ensembles(seed_ensembles)	Pre-built SeedEnsemble instances
from_dict(trained_model_paths, verbose=False)	Dict mapping classifier name → trained-model registry path (.json or .csv); each value is dispatched through SeedEnsemble.from_any
from_json(json_path, verbose=False)	Top-level results map (ClassifierEnsemble_{cv}.json) written by TrainingModel.fit()

Inference

ce.predict_proba(X: pd.DataFrame) -> np.ndarray             # consensus, (n_samples, 2)
ce.predict_with_uncertainty(X: pd.DataFrame, threshold: float = 0.5)
# → (mean, std, confidence, prediction, per_classifier_dict)

Inspection

ce.classifiers          # list[str]: classifier class names in registration order
ce[name]                # SeedEnsemble for the named classifier
len(ce)                 # number of classifiers

MetricsEnsemble

MetricsEnsemble(
    classifier_ensemble: ClassifierEnsemble,
    features_df: pd.DataFrame,
    y_true: pd.Series | np.ndarray,
    kind: Literal["prediction", "training"] = "prediction",
    output_dir: str | None = None,
    root_dir: str | None = None,
    overwrite: bool = False,
    n_jobs: int = 1,
    verbose: bool = False,
)

MetricsEnsemble.from_file(
    model_filepath: str,
    features_path: str,
    features_label_csv: str,
    eruption_dates: list[str] | None = None,
    kind: Literal["prediction", "training"] = "prediction",
    output_dir: str | None = None,
    root_dir: str | None = None,
    overwrite: bool = False,
    n_jobs: int = 1,
    verbose: bool = False,
) -> MetricsEnsemble

Method	Notes
me.compute() -> Self	Per-seed metric loop. Writes only the (n_samples, n_seeds) y_proba.csv / y_pred.csv matrices under classifiers/{ClfName}/predictions/. metrics, y_probas, y_preds stay in memory; no per-seed JSON is produced. Idempotent once y_probas is populated.
me.plot_aggregate(include_plots=None, exclude_plots=None) -> list[str]	Aggregate plots per classifier — ROC, PR, threshold analysis, g-mean curve, MCC curve. Writes figures/aggregate/{plot_name}.{png,csv} per classifier.
me.plot_seed(include_plots=None, exclude_plots=None) -> list[str]	Per-seed plots — same dispatcher catalogue. Writes figures/{plot_name}/{seed:05d}.png per classifier in parallel via joblib.
me.metrics	dict[str, pd.DataFrame] — populated after compute()
me.save(path=None) / MetricsEnsemble.load(path)	joblib round-trip of the full instance to MetricsEnsemble.pkl.

BaseEnsemble

class BaseEnsemble:
    def save(self, path: str) -> None
    @classmethod
    def load(cls, path: str) -> Self

Joblib save/load mixin inherited by SeedEnsemble and ClassifierEnsemble. Imported from eruption_forecast.ensemble.base_ensemble.

ClassifierComparator

ClassifierComparator(
    metrics_ensemble: MetricsEnsemble,
    metrics: str | list[str] | None = None,
    output_dir: str | None = None,
)

ClassifierComparator.from_classifier_ensemble(
    classifier_ensemble: ClassifierEnsemble,
    features_df: pd.DataFrame,
    y_true: pd.Series | np.ndarray,
    kind: Literal["training", "prediction"] = "training",
    output_dir: str | None = None,
    root_dir: str | None = None,
    metrics: str | list[str] | None = None,
    n_jobs: int = 1,
    verbose: bool = False,
) -> ClassifierComparator

Method	Returns
cc.get_ranking()	pd.DataFrame - cross-classifier ranking
cc.plot_all()	None - writes ranking plots under {output_dir}/comparison/figures/

Imported from eruption_forecast.model.classifier_comparator. Usually instantiated indirectly via em.compare() or fm.EvaluationModel.compare().

TremorData

Thin wrapper around a tremor CSV. Imported as TremorData from the package root.

TremorData(df: pd.DataFrame)                  # wrap an in-memory frame
TremorData.from_csv(path: str) -> TremorData  # classmethod

@cached_property accessors: df, start_date, end_date, filename, basename, filetype.

---

LabelData

Thin wrapper around a label CSV. Imported as LabelData from the package root.

LabelData(df: pd.DataFrame)
LabelData.from_csv(path: str) -> LabelData

@cached_property accessors: df, parameters (dict parsed from filename - window_size, window_step, window_step_unit, day_to_forecast), filename, basename.

Logger helpers

from eruption_forecast import enable_logging, disable_logging
from eruption_forecast.logger import set_log_level, set_log_directory

enable_logging()              # restore console + file handlers
disable_logging()             # remove every loguru handler
set_log_level(level: str)     # "DEBUG" | "INFO" | "WARNING" | "ERROR" | "CRITICAL"
set_log_directory(dir: str)   # move the log file to a new directory (created if absent)

---

Telegram helpers

from eruption_forecast import notify, send_telegram_notification

@notify(label: str)
def my_func(): ...

send_telegram_notification(
    message: str,
    files: list[str] | None = None,
    file_caption: str | None = None,
    send_as_document: bool = False,
)

Credentials are read from environment (TELEGRAM_BOT_TOKEN, TELEGRAM_CHAT_ID). Both helpers degrade gracefully when the env vars are absent - they emit a warning and skip the network call instead of raising.
