​Prediction of Hilbertian autoregressive processes: A Recurrent Neural Network approach​

This study compares classical prediction methods for Hilbert-space autoregressive processes (ARH) with a Recurrent Neural Network (LSTM) approach, showing that LSTMs outperform for nonlinear data, while traditional statistical models remain competitive in certain cases.
