Neural 🧠 Forecast

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

CI Python PyPi conda-nixtla License docs

NeuralForecast offers a large collection of neural forecasting models focused on their usability, and robustness. The models range from classic networks like MLP, RNNs to novel proven contributions like NBEATS, TFT and other architectures.

💻 Installation


You can install NeuralForecast's released version from the Python package index pip with:

pip install neuralforecast

(Installing inside a python virtualenvironment or a conda environment is recommended.)


Also you can install NeuralForecast's released version from conda with:

conda install -c conda-forge neuralforecast

(Installing inside a python virtual environment or a conda environment is recommended.)

Dev Mode If you want to make some modifications to the code and see the effects in real time (without reinstalling), follow the steps below:
git clone
cd neuralforecast
pip install -e .

🏃🏻‍♀️🏃 Getting Started

To get started follow this guide, where we explore NBEATS, extend it towards probabilistic predictions and exogenous variables.

Or follow this simple example where we train the NBEATS model and predict the classic Box-Jenkins air passengers dataset.

import numpy as np
import pandas as pd
from IPython.display import display, Markdown

import matplotlib.pyplot as plt
from neuralforecast import NeuralForecast
from neuralforecast.models import NBEATS, NHITS
from neuralforecast.utils import AirPassengersDF

# Split data and declare panel dataset
Y_df = AirPassengersDF
Y_train_df = Y_df[Y_df.ds<='1959-12-31'] # 132 train
Y_test_df = Y_df[Y_df.ds>'1959-12-31'] # 12 test

# Fit and predict with N-BEATS and N-HiTS models
horizon = len(Y_test_df)
models = [NBEATS(input_size=2 * horizon, h=horizon, max_epochs=50),
          NHITS(input_size=2 * horizon, h=horizon, max_epochs=50)]
nforecast = NeuralForecast(models=models, freq='M')
Y_hat_df = nforecast.predict().reset_index()

# Plot predictions
fig, ax = plt.subplots(1, 1, figsize = (20, 7))
Y_hat_df = Y_test_df.merge(Y_hat_df, how='left', on=['unique_id', 'ds'])
plot_df = pd.concat([Y_train_df, Y_hat_df]).set_index('ds')

plot_df[['y', 'NBEATS', 'NHITS']].plot(ax=ax, linewidth=2)

ax.set_title('AirPassengers Forecast', fontsize=22)
ax.set_ylabel('Monthly Passengers', fontsize=20)
ax.set_xlabel('Timestamp [t]', fontsize=20)
ax.legend(prop={'size': 15})

📖 Why?

There is a shared belief in Neural forecasting methods' capacity to improve our 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.

🔬 Accuracy & ⏲ Speed

Industry/Competition Proven Methods

An extensive empirical evaluation is critical to generate confidence and promote the adoption and development of novel methods. For this reason, we replicate and verify the results of our implementation of the following industry/competition-proven methods: ESRNN, NBEATS, NHITS, and TFT. If you are interested in reproducing the results, check the experiments here.

Simple and Efficient Method's Comparison

Like core.StatsForecast, the core.NeuralForecast wrapper class allows us to easily compare any model in the collection to select or ensemble the best performing methods. Aditionally it offers a high-end interface that operates with (potentially large) sets of time series data stored in pandas DataFrames. The core.NeuralForecast efficiently parallelizes computation across CPU or GPU resources. Check the experiments here.
