Time Series Forecasting Using Recurrent Neural Network and Vector Autoregressive Model: When and How

Given the resurgence of neural network-based techniques in recent years, it is important for data science practitioner to understand how to apply these techniques and the trade-offs between neural network-based and traditional statistical methods. This lecture discusses two specific techniques, real-world applications and their advantages and disadvantages, and demonstrations of exploratory time series data analysis.

  • Vector Autoregressive (VAR) Models – one of the most important class of multivariate time series statistical models applied in finance.
  • Recurrent Neural Network (RNN) - a neural network architecture suitable for time series forecasting.
