Forecasting Financial Budget Time Series: ARIMA Random Walk vs LSTM Neural Network

Abstract


Financial time series are volatile, non-stationary
and non-linear data that are affected by external economic
factors. There is several performant predictive approaches such
as univariate ARIMA model and more recently Recurrent Neural
Network. The accurate forecasting of budget data is a strategic
and challenging task for an optimal management of resources,
it requires the use of the most accurate model. We propose
a predictive approach that uses and compares the Machine
Learning ARIMA model and Deep Learning Recurrent LSTM
model. The application and the comparative analysis shows that
the LSTM model outperforms the ARIMA model, mainly thanks
to the LSTMs ability to learn non-linear relationship from data.
