Problem

  • Any quantity varying over time can be represented as a time series: sales numbers, rainfall, stock prices, CO2 emissions, Internet clicks, network traffic, etc. Time series forecasting — the ability to predict the future evolution of a time series— is a key capability in many domains where anticipation is important. Although there exist many models and tools for time series, they are often non-trivial to work with, because they each have their own intricacies and cannot always be used in the same way

Solution

  • Darts is our open source library for time series forecasting, attempting to simplify time series processing and forecasting in Python

Impact

  • Speed-up the process related to time series forecasting in order to
    – Decrease costs
    – Improve accuracy
    – Reduce manual work
