### Project: Interventional Whittle Sum-Product Networks

##### Description

##### Details

Whittle sum-product networks [1] model the joint distribution of multivariate time series by leveraging the Whittle approximation, casting the likelihood in the frequency domain, and place a complex-valued sum-product network over the frequencies. The conditional independence relations among the time series can then be determined efficiently in the spectral domain. Granger causality [2] is the framework that deals with causal effects in the time series domain. In this project we will develop an interventional Whittle SPN that can effectively handle interventions in the time series.
