Machine Learning and Mortgage Analytics: Predicting Defaults in Agency Pools
The mortgage market in the US is the perfect candidate for the application of machine learning techniques, being such a sizeable market with vast amounts of data open to the public. In the US, mortgages are bundled, sold by the Government Sponsored Agencies (GSEs), who guarantee the investors against mortgage defaults. Typical agency prepayment models include many effects, but do not implicitly consider defaults due to this guarantee. We have shown that applying machine learning techniques produces good predictive power on defaults in agency pools. In this talk I will briefly introduce the mortgage markets, define the problem that we are solving, and show the results of the study. Given the successful outcomes, more ambitious projects are planned and will be discussed.
