Why Greykite?
-------------
The Greykite library provides flexible, intuitive and fast forecasts through its flagship algorithm, Silverkite.
Silverkite algorithm works well on most time series, and is especially adept for those with changepoints in trend or seasonality,
event/holiday effects, and temporal dependencies.
Its forecasts are interpretable and therefore useful for trusted decision-making and insights.
The Greykite library provides a framework that makes it easy to develop a good forecast model,
with exploratory data analysis, outlier/anomaly preprocessing, feature extraction and engineering, grid search,
evaluation, benchmarking, and plotting.
Other open source algorithms can be supported through Greykite’s interface to take advantage of this framework,
as listed below.
For a demo, please see our `quickstart <https://linkedin.github.io/greykite/get_started>`_.
Distinguishing Features
-----------------------
* Flexible design
* Provides time series regressors to capture trend, seasonality, holidays,
changepoints, and autoregression, and lets you add your own.
* Fits the forecast using a machine learning model of your choice.
* Intuitive interface
* Provides powerful plotting tools to explore seasonality, interactions, changepoints, etc.
* Provides model templates (default parameters) that work well based on
data characteristics and forecast requirements (e.g. daily long-term forecast).
* Produces interpretable output, with model summary to examine individual regressors,
and component plots to visually inspect the combined effect of related regressors.
* Fast training and scoring
* Facilitates interactive prototyping, grid search, and benchmarking.
Grid search is useful for model selection and semi-automatic forecasting of multiple metrics.
* Extensible framework
* Exposes multiple forecast algorithms in the same interface,
making it easy to try algorithms from different libraries and compare results.
* The same pipeline provides preprocessing, cross-validation,
backtest, forecast, and evaluation with any algorithm.
Algorithms currently supported within Greykite’s modeling framework:
* Silverkite (Greykite’s flagship algorithm)
* `Facebook Prophet <https://facebook.github.io/prophet/>`_
* `Auto Arima <https://alkaline-ml.com/pmdarima/>`_
Notable Components
------------------
Greykite offers components that could be used within other forecasting
libraries or even outside the forecasting context.
* ModelSummary() - R-like summaries of `scikit-learn` and `statsmodels` regression models.
* ChangepointDetector() - changepoint detection based on adaptive lasso, with visualization.
* SimpleSilverkiteForecast() - Silverkite algorithm with `forecast_simple` and `predict` methods.
* SilverkiteForecast() - low-level interface to Silverkite algorithm with `forecast` and `predict` methods.
* ReconcileAdditiveForecasts() - adjust a set of forecasts to satisfy inter-forecast additivity constraints.
Usage Examples
--------------
You can obtain forecasts with only a few lines of code:
.. code-block:: python
from greykite.common.data_loader import DataLoader
from greykite.framework.templates.autogen.forecast_config import ForecastConfig
from greykite.framework.templates.autogen.forecast_config import MetadataParam
from greykite.framework.templates.forecaster import Forecaster
from greykite.framework.templates.model_templates import ModelTemplateEnum
# Defines inputs
df = DataLoader().load_bikesharing().tail(24*90) # Input time series (pandas.DataFrame)
config = ForecastConfig(
metadata_param=MetadataParam(time_col="ts", value_col="count"), # Column names in `df`
model_template=ModelTemplateEnum.AUTO.name, # AUTO model configuration
forecast_horizon=24, # Forecasts 24 steps ahead
coverage=0.95, # 95% prediction intervals
)
# Creates forecasts
forecaster = Forecaster()
result = forecaster.run_forecast_config(df=df, config=config)
# Accesses results
result.forecast # Forecast with metrics, diagnostics
result.backtest # Backtest with metrics, diagnostics
result.grid_search # Time series CV result
result.model # Trained model
result.timeseries # Processed time series with plotting functions
For a demo, please see our `quickstart <https://linkedin.github.io/greykite/get_started>`_.
