Please note that the project is still in beta phase. Please report any issues you encounter or suggestions you have. We will do our best to address them quickly. Contributions are very welcome!

NeuralProphet

A Neural Network based Time-Series model, inspired by Facebook Prophet and AR-Net, built on PyTorch.

Documentation

The documentation page may not we entirely up to date. Docstrings should be reliable, please refer to those when in doubt. We are working on an improved documentation. We appreciate any help to improve and update the docs.

For a visual introduction to NeuralProphet, view this presentation.

Contribute

We compiled a Contributing to NeuralProphet page with practical instructions and further resources to help you become part of the family.

Tutorials

Open All Collab

There are several example notebooks to help you get started.

You can find the datasets used in the tutorials, including data preprocessing examples, in our neuralprophet-data repository.

Please refer to our documentation page for more resources.

Minimal example

from neuralprophet import NeuralProphet

After importing the package, you can use NeuralProphet in your code:

m = NeuralProphet()
metrics = m.fit(df)
forecast = m.predict(df)

You can visualize your results with the inbuilt plotting functions:

fig_forecast = m.plot(forecast)
fig_components = m.plot_components(forecast)
fig_model = m.plot_parameters()

If you want to forecast into the unknown future, extend the dataframe before predicting:

m = NeuralProphet().fit(df, freq="D")
df_future = m.make_future_dataframe(df, periods=30)
forecast = m.predict(df_future)
fig_forecast = m.plot(forecast)

Install

You can now install neuralprophet directly with pip:

pip install neuralprophet

Install options

If you plan to use the package in a Jupyter notebook, we recommended to install the 'live' version:

pip install neuralprophet[live]

This will allow you to enable plot_live_loss in the fit function to get a live plot of train (and validation) loss.

If you would like the most up to date version, you can instead install direclty from github:

git clone <copied link from github>
cd neural_prophet
pip install .

Model features

  • Autocorrelation modelling through AR-Net
  • Piecewise linear trend with optional automatic changepoint detection
  • Fourier term Seasonality at different periods such as yearly, daily, weekly, hourly.
  • Lagged regressors (measured features, e.g temperature sensor)
  • Future regressors (in advance known features, e.g. temperature forecast)
  • Country holidays & recurring special events
  • Sparsity of coefficients through regularization
  • Plotting for forecast components, model coefficients as well as final predictions
  • Automatic selection of training related hyperparameters
  • Support for panel data by building global forecasting models.

Coming up soon

For details, please view the Development Timeline.

The next versions of NeuralProphet are expected to cover a set of new exciting features:

  • Logistic growth for trend component.
  • Uncertainty estimation of predicted values
  • Incorporate time series featurization for improved forecast accuracy.
  • Model bias modelling/correction with secondary model
  • Multimodal dynamics: unsupervised automatic modality-specific forecast.

For a complete list of all past and near-future changes, please refer to the changelogs.
