skforecast 0.4.1

Forecasting time series with scikitlearn regressors

skforecast

Time series forecasting with scikit-learn regressors.

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

Documentation: https://joaquinamatrodrigo.github.io/skforecast/

Version 0.4 has undergone a huge code refactoring. Main changes are related to input-output formats (only pandas series and dataframes are allowed although internally numpy arrays are used for performance) and model validation methods (unified into backtesting with and without refit). Changelog

Installation

pip install skforecast

Specific version:

pip install skforecast==0.3

Latest (unstable):

pip install git+https://github.com/JoaquinAmatRodrigo/skforecast#master

The most common error when importing the library is:

'cannot import name 'mean_absolute_percentage_error' from 'sklearn.metrics'.

This is because the scikit-learn installation is lower than 0.24. Try to upgrade scikit-learn with

pip3 install -U scikit-learn

Dependencies

• numpy>=1.20.1
• pandas>=1.2.2
• tqdm>=4.57.0
• scikit-learn>=1.0.1
• statsmodels>=0.12.2

Features

• Create recursive autoregressive forecasters from any scikit-learn regressor
• Create multi-output autoregressive forecasters from any scikit-learn regressor
• Grid search to find optimal hyperparameters

• Backtesting
• Prediction interval estimated by bootstrapping
• Get predictor importance

Introduction

A time series is a sequence of data arranged chronologically, in principle, equally spaced in time. Time series forecasting is the use of a model to predict future values based on previously observed values, with the option of also including other external variables.

When working with time series, it is seldom needed to predict only the next element in the series (t+1). Instead, the most common goal is to predict a whole future interval (t+1, ..., t+n) or a far point in time (t+n). There are several strategies that allow generating this type of multiple predictions.

Recursive multi-step forecasting

Since the value of t(n) is required to predict the point t(n-1), and t(n-1) is unknown, it is necessary to make recursive predictions in which, each new prediction, is based on the previous one. This process is known as recursive forecasting or recursive multi-step forecasting.

The main challenge when using scikit-learn models for recursive multi-step forecasting is transforming the time series in an matrix where, each value of the series, is related to the time window (lags) that precedes it. This forecasting strategy can be easily generated with the classes ForecasterAutoreg and ForecasterAutoregCustom.

Time series transformation into a matrix of 5 lags and a vector with the value of the series that follows each row of the matrix.

Time series transformation including an exogenous variable.

Direct multi-step forecasting

This strategy consists of training a different model for each step. For example, to predict the next 5 values of a time series, 5 different models are trainded, one for each step. As a result, the predictions are independent of each other. This forecasting strategy can be easily generated with the ForecasterAutoregMultiOutput class (changed in version 0.1.9).

Time series transformation into the matrices needed to train a direct multi-step forecaster.

Multiple output forecasting

Certain models are capable of simultaneously predicting several values of a sequence (one-shot), for example, LSTM neural networks. This strategy is not implemented in skforecast.
