Neural 🧠 Forecast

User friendly state-of-the-art neural forecasting models

NeuralForecast offers a large collection of neural forecasting models focusing on their performance, usability, and robustness. The models range from classic networks like RNN to the latest transformers: MLP, LSTM, GRU,RNN,TCN, DeepAR, NBEATS, NBEATSx, NHITS, DLinear,TFT, Informer, AutoFormer, FedFormer, PatchTST,StemGNN, and TimesNet.

Installation

You can install NeuralForecast with:

pip install neuralforecast

conda install -c conda-forge neuralforecast

Vist our Installation Guide for further details.

Quick Start

Minimal Example

from neuralforecast import NeuralForecast
from neuralforecast.models import NBEATS
from neuralforecast.utils import AirPassengersDF

nf = NeuralForecast(
    models = [NBEATS(input_size=24, h=12, max_steps=100)],
    freq = 'M'
)

nf.fit(df=AirPassengersDF)
nf.predict()

Why?

There is a shared belief in Neural forecasting methods' capacity to improve forecasting pipeline's accuracy and efficiency.

Unfortunately, available implementations and published research are yet to realize neural networks' potential. They are hard to use and continuously fail to improve over statistical methods while being computationally prohibitive. For this reason, we created NeuralForecast, a library favoring proven accurate and efficient models focusing on their usability.

Features

Fast and accurate implementations of MLP, LSTM, GRU,RNN,TCN, DeepAR, NBEATS, NBEATSx, NHITS, DLinear,TFT, Informer, AutoFormer, FedFormer, PatchTST,StemGNN, and TimesNet. See the entire collection here.
Support for exogenous variables and static covariates.
Interpretability methods for trend, seasonality and exogenous components.
Probabilistic Forecasting with adapters for quantile losses and parametric distributions.
Train and Evaluation Losses with scale-dependent, percentage and scale independent errors, and parametric likelihoods.
Automatic Model Selection with distributed automatic hyperparameter tuning.
Familiar sklearn syntax: .fit and .predict.

Highlights

Official NHITS implementation, published at AAAI 2023. See paper and experiments.
Official NBEATSx implementation, published at the International Journal of Forecasting. See paper.
Unified withStatsForecast, MLForecast, and HierarchicalForecast interface NeuralForecast().fit(Y_df).predict(), inputs and outputs.
Built-in integrations with utilsforecast and coreforecast for visualization and data-wrangling efficient methods.
Integrations with Ray and Optuna for automatic hyperparameter optimization.
Predict with little to no history using Transfer learning. Check the experiments here.
