Who is this presentation for?

  • Data scientists, developers, and analysts




ML gets a lot of hype, but its classical predecessors are still immensely powerful, especially in the time series space. Error, trend, seasonality forecast (ETS), autoregressive integrated moving average (ARIMA), and Holt-Winters are three classical methods that are not only incredibly popular but also excellent time series predictors. In fact, these classical methods outperform several other ML methods including long short-term memory (LTSM) and recurrent neural networks (RNNs) in one-step forecasting.

Anais Dotis dives into how the Holt-Winters forecasting algorithm works. Then you’ll use the HOLT_WINTERS() function with InfluxData to make your own time series forecast.

Prerequisite knowledge

  • Experience with calculus

What you'll learn

  • Understand when to use Holt-Winters, how single exponential smoothing works, the optimization for single exponential smoothing, how single exponential smoothing relates to triple exponential smoothing and Holt-Winters, and how you can use InfluxDB’s built-in multiplicative Holt-Winters function to generate predictions on your time series data
