Architecture
This page is the structural reference for eruption_forecast: every module under src/,
the top-level pipeline, how the model and ensemble classes relate, what flows between
stages on disk, and the utility surface that holds the rest together.

ForecastModel is the orchestrator that calls every box in sequence.
The dashed arrows are also the method-chain order:
fm.calculate(...).train(...).predict(...).evaluate(...).explain(...).
CalculateTremor reads seismic traces day-by-day from a SeismicDataSource and
dispatches each day to the configured tremor kernels (rsam.py, dsar.py, shannon_entropy.py).
Per-day CSVs are written to tremor/daily/, then concatenated into the merged tremor
CSV at the station root. TremorData is a thin wrapper that exposes df, start_date, end_date,
sampling-rate validation, and the CSV filename / basename / filetype triple.
Two builders share the same output shape (id, is_erupted) but differ in how positives are placed:
-
LabelBuilder- sliding window over the full date range;day_to_forecastcontrols the look-ahead window.include_eruption_date=False(default) still marks the eruption day as positive, givingday_to_forecast + 1positive days per eruption. -
DynamicLabelBuilder- extendsLabelBuilderwith a per-eruption three-phase build: (1) zero frames per eruption, (2) concat + deduplicate datetimes, (3) mark positives per eruption. Solves the issue where overlapping look-ahead windows collide inLabelBuilder.
LabelBuilder - one global window over the full date range

LabelData parses parameters (window_size, window_step, window_step_unit, day_to_forecast)
directly out of the label filename so a CSV alone is enough to rehydrate the build context.

TremorMatrixBuilder.build() validates sample counts per window against minimum_completion
and skips short windows so tsfresh never sees ragged input.
FeaturesBuilder runs per-column independent extractions so adding a new tremor
band does not invalidate the cached results for the others.
The model layer follows a mixin pattern:
-
BaseModel- abstract base for every stage. Owns the date/window grid, the lazytremor_dataaccessor,output_dirresolution,n_jobsclamping, the content-addressable cache identity helpers (build_identity,compute_hash,_canonicalize,tremor_fingerprint,cache_path), and the dual-mode joblibsave(identity=None, path=None)/ cache-onlyload(stage_dir, identity). Whenidentityis supplied,save()writes to{stage_dir}/{hash}.{ClassName}.pkl(plus a.params.jsonsidecar). Whenidentityis omitted, the legacy{output_dir}/{ClassName}_{basename}.pkljoblib dump is preserved for standalone manual saves. Subclasses implementset_directories,create_directories,validate,describe,to_dict,to_prompt,build_label,extract_features, and overridestage_dir+build_identitywhen they participate in the cache. -
TrainingModel(BaseModel)-build_label → extract_features → fit.fit()runs per-seedGridSearchCVinjoblib.Parallelover the selected classifiers, writes a per-classifier trained-model JSON registry viasave_model_json, bundles every seed into aSeedEnsembleand every classifier into aClassifierEnsemble, then callsself.save(self.build_identity())so the cache pickle lands at{training_dir}/{hash}.TrainingModel.pklwith a matching sidecar. -
PredictionModel(BaseModel)-build_label → extract_features → forecast. Cache identity embeds the upstreamtraining_hash(a constructor param threaded byForecastModel.predict), so re-training automatically invalidates downstream forecasts.forecast()callsself.save(self.build_identity()); cache files live at{prediction_dir}/{hash}.PredictionModel.pkl. -
EvaluationModel(BaseModel)- no cache; dispatches onmodel.kind("training"or"prediction"). Output is namespaced underevaluation/{kind}/so both modes can coexist. -
ExplanationModel(BaseModel)- per-seed SHAP explanations over a fittedClassifierEnsemble. Reuses the upstreamTrainingModelorPredictionModeland dispatches onmodel.kind. Restricted to tree classifiers (RF / lite-rf / GB / XGB); non-tree classifiers are skipped at theExplainerEnsembleloop with a warning. Output is namespaced underexplanation/{kind}/; cache pickles land at{explanation_dir}/{hash}.ExplanationModel.pkl(already mode-namespaced so training-reuse and prediction-reuse caches never collide). -
ForecastModel- the orchestrator. Not aBaseModelsubclass - it ownsCalculateTremor, builds the four stage classes lazily, and captures stage kwargs into aForecastConfigfor round-tripping.
ClassifierModel is the per-classifier descriptor (sklearn estimator + hyperparameter grid + slug).
ClassifierComparator consumes the in-memory MetricsEnsemble cached on EvaluationModel to rank classifiers head-to-head.

MetricsEnsemble and ExplainerEnsemble are both deliberately kept out of ensemble/__init__.py and imported via their full module paths (eruption_forecast.ensemble.metrics_ensemble, eruption_forecast.ensemble.explainer_ensemble) to keep the subpackage free of import cycles back through utils.ml and plots/.
SeismicDataSource is the read interface: get(date) -> obspy.Stream. Two concrete implementations:
-
SDS- pure local read from{root}/{year}/{network}/{station}/{channel}.D/{file}. -
FDSN- pulls from a remote FDSN service, then caches the downloaded MSEED into a local SDS layout (download_dir). Repeat calls with the same date hit the local cache.
apply_nature_style() normalises every figure to a Nature/Science-friendly palette and font stack.
Each plot module is a thin functional wrapper around matplotlib (and seaborn where appropriate) - see Visualization for the catalog and output paths.
ForecastConfig is the round-trip record for ForecastModel. Its six sub-configs match the stage method signatures one-for-one:
ForecastConfig
├── model: BaseForecastConfig
├── calculate: ForecastCalculateConfig | None
├── train: ForecastTrainConfig | None
├── predict: ForecastPredictConfig | None
├── evaluate: ForecastEvaluateConfig | None
└── explain: ForecastExplainConfig | None
TrainingConfig, PredictionConfig, EvaluationConfig, and ExplanationConfig each mirror their stage model's __init__ directly and are the standalone equivalents used when the model runs outside ForecastModel. Every stage model auto-calls save_config() at the end of its main run method (fit() / forecast() / evaluate() / explain()), so a standalone run always leaves a YAML snapshot next to its artefacts. The upstream model parameter on EvaluationConfig and ExplanationConfig is intentionally omitted because it is always a live model instance.
notify(task) wraps a function with success and error Telegram messages (MarkdownV2 body, hostname, elapsed time, exception details). timer(name, send_to=None) logs the wrapped function's elapsed wall-clock time via loguru; passing send_to="telegram" also mirrors the message to Telegram.
Both decorators delegate to TelegramNotification (notification/telegram.py), a fluent-chain client wrapping the Telegram Bot API. It exposes send_message(...), send_document(...), send_photo(...), and send_media_group(...); every send method returns self so calls can be chained (tn.send_message(...).send_document(...)). Credentials are resolved from constructor arguments or the TELEGRAM_BOT_TOKEN / TELEGRAM_CHAT_ID environment variables. Every network failure is logged and swallowed, so a dead network never blocks the caller. scenarios.py uses this class directly to ship each per-scenario forecast PNG next to a title message.
Nine focused modules that the rest of the codebase pulls from - see the table in 6.

A cache hit on TrainingModel short-circuits everything in the training/ box;
a cache hit on PredictionModel short-circuits the prediction/ box;
a cache hit on ExplanationModel short-circuits the per-classifier SHAP pass.
Evaluation is never cached - the on-disk matrices act as the cache and MetricsEnsemble.compute() is idempotent in memory once y_probas is populated.

utils/ml.save_model_json writes the per-classifier trained-model JSON registry (one record per seed, each with the inline top-N feature list and the path to the seed's .pkl). TrainingModel.build_seed_ensemble reads that registry via SeedEnsemble.from_any to package every seed into a SeedEnsemble, and the per-classifier SeedEnsembles are then merged into a ClassifierEnsemble (build_classifier_ensemble). All three steps run at the end of TrainingModel.fit().
utils/formatting.slugify is what turns "Scenario 1" into scenario-1 for the per-scenario output_dir used in scenarios.py.
