Sigrid Keydana – Time series shootout – ARIMA vs. LSTM

Abstract: Time series shootout – ARIMA vs. LSTM

When it comes to time series forecasting, we usually resort to time-proven, reliable, strikingly elegant in her simplicity ARIMA. In R, with auto.arima, you can get a decent forecast in a single line of code. In a world where deep learning breaks new records almost every week (it seems), you might ask, how well are deep neural networks doing here? Can we keep up with ARIMA, perhaps even do some things better? In this session, we’ll find out. We’ll have ARIMA and a deep network play against each other, each providing forecasts for systematic artificial benchmarks as well as real world datasets!
