Skforecast is a Python library that eases using scikit-learn regressors as single and multi-step forecasters. It also works with any regressor compatible with the scikit-learn API (LightGBM, XGBoost, CatBoost, ...).

Why use skforecast?

The fields of statistics and machine learning have developed many excellent regression algorithms that can be useful for forecasting, but applying them effectively to time series analysis can still be a challenge. To address this issue, the skforecast library provides a comprehensive set of tools for training, validation and prediction in a variety of scenarios commonly encountered when working with time series. The library is built using the widely used scikit-learn API, making it easy to integrate into existing workflows. With skforecast, users have access to a wide range of functionalities such as feature engineering, model selection, hyperparameter tuning and many others. This allows users to focus on the essential aspects of their projects and leave the intricacies of time series analysis to skforecast. In addition, skforecast is developed according to the following priorities:

• Fast and robust prototyping. ⚡
• Validation and backtesting methods to have a realistic assessment of model performance. 🔍
• Models must be deployed in production. 🔨
• Models must be interpretable. 🔮

• ForecasterAutoregDirect and ForecasterAutoregMultiVariate include the n_jobs argument in their fit method, allowing multi-process parallelization for improved performance.
• All backtesting and grid search functions have been extended to include the n_jobs argument, allowing multi-process parallelization for improved performance.
• Argument refit now can be also an integer in all backtesting dependent functions in modules model_selection, model_selection_multiseries, and model_selection_sarimax. This allows the Forecaster to be trained every this number of iterations.
• ForecasterAutoregMultiSeries and ForecasterAutoregMultiSeriesCustom can be trained using series of different lengths. This means that the model can handle datasets with different numbers of data points in each series.
• Bug fixes and performance improvements.

A Forecaster object in the skforecast library is a comprehensive container that provides essential functionality and methods for training a forecasting model and generating predictions for future points in time.

The skforecast library offers a variety of forecaster types, each tailored to specific requirements such as single or multiple time series, direct or recursive strategies, or custom predictors. Regardless of the specific forecaster type, all instances share the same API.
