Fig. 3: Input window and output horizon forecast scenarios.
From: Forecasting of in situ electron energy loss spectroscopy
a “Long window, short horizon” scenario with an eight timestep window and one timestep horizon, demonstrating deceptively good results due to autocorrelation. b “Short window, long horizon” scenario with a 3 timestep window and 8 timestep horizon, demonstrating poor results. c “Long window, long horizon” scenario, with an 8 timestep window and 8 timestep horizon, indicating good prediction with minimal autocorrelation. The green lines indicate spectra from the input window, the blue lines indicate true future spectra to predict, and the orange line indicates spectra predicted by the LSTM. Note that the plots on the right show only the last spectrum from the input window (in green).
