In modeltime.gluonts: 'GluonTS' Deep Learning

modeltime.gluonts

Deep Learning for Time Series, simplified.

Important: This package is exprimental. Functions may change until the package matures.

Modeltime GluonTS integrates the Python GluonTS Deep Learning Library, making it easy to develop forecasts using Deep Learning for those that are comfortable with the Modeltime Forecasting Workflow.

Using deep_ar(), which connects to GluonTS DeepAREstimator().

modeltime.gluonts is currently available on GitHub only. Not on CRAN yet.

remotes::install_github("business-science/modeltime.gluonts")

Important: Use install_gluonts() to set up the “r-gluonts” python environment used by modeltime.gluonts. You only need to do this once, when you first set up the package.

# GluonTS Installation
# - This sets up the Python Environment
# - Only need to run 1-time, then you're set!
install_gluonts()

My Talk on High-Performance Time Series Forecasting

Time series is changing. Businesses now need 10,000+ time series forecasts every day. This is what I call a High-Performance Time Series Forecasting System (HPTSF) - Accurate, Robust, and Scalable Forecasting.

High-Performance Forecasting Systems will save companies MILLIONS of dollars. Imagine what will happen to your career if you can provide your organization a “High-Performance Time Series Forecasting System” (HPTSF System).

I teach how to build a HPTFS System in my High-Performance Time Series Forecasting Course. If interested in learning Scalable High-Performance Forecasting Strategies then take my course. You will learn:
