Neuralforecast
Neuralforecast is a neural time series forecasting library designed to predict future values for one or multiple series using deep learning architectures. It functions as a distributed machine learning forecasting framework that enables the training of global models across multiple time series to improve generalization through cross-learning.
The project distinguishes itself as a probabilistic forecasting toolkit that produces uncertainty intervals and probability distributions rather than single point estimates. It also includes a hierarchical forecast reconciler to ensure that predictions across different organizational or geographical levels remain consistent with their aggregate totals.
The library covers a broad range of capabilities, including the integration of exogenous variables, automated hyperparameter optimization, and transfer learning. It provides tools for model validation via cross-validation and sliding window techniques, as well as the ability to distribute training workloads across compute clusters using Spark.
The system supports model persistence via cloud storage integration and provides mechanisms for interpreting forecast components such as trend and seasonality.
