About The Project

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. 🔮

Forecasters

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.

Main User Guides

• Introduction to time series and forecasting

• Recursive multi-step forecasting

• Direct multi-step forecasting

• Independent multi-series forecasting

• Dependent multi-series forecasting (Multivariate forecasting)

• Backtesting (validation) of forecasting models

• Hyperparameter tuning and lags selection of forecasting models

• Probabilistic forecasting

• Using forecasters in production
