System and method of detecting and assessing multiple types of risks related to mortgage lending
First Claim
1. A system for detecting and assessing lending risks, the system comprising:
- a computer system comprising one or more computing devices, the computer system programmed, via executable code modules, to implement;
a combined risk detection model for detecting and assessing data indicative of a plurality of risks in loan application data, the combined risk detection model configured to receive as input a plurality of input features extracted from two or more of a plurality of risk detection models, the plurality of risk detection models comprising;
a first risk detection model configured to generate a first risk model score that is indicative of the presence of a first risk in the loan application data;
a second risk detection model configured to generate a second risk model score that is indicative of the presence of a second risk in the loan application data; and
a third risk detection model configured to generate a third risk model score that is indicative of the presence of a third risk in the loan application data, wherein the first risk, the second risk, and the third risk are different risks,wherein the computer system is further programmed to;
determine combinability of the plurality of risk detection models based at least partly on evaluating predictive performance of scores from one or more combinations of the risk detection models against historical transactions data;
extract input features from the risk detection models that are determined to be combinable, the input features created from a mathematical combination of the scores and additional data, wherein the input features are extracted from the two or more risk detection models by mathematically combining scores from the plurality of risk detection models for input into the combined risk detection model, the input features being selected as based at least in part on a comparison of the predictive performance of the plurality of risk detection models and a selection of a modeling method used to construct the combined risk detection model; and
generate a composite risk score based at least in part on the scores from the models determined to be combinable and the extracted input features; and
a score reporting module that reports the composite risk score generated by the combined risk detection model.

Abstract
Embodiments include systems and methods of detecting and assessing multiple types of risks related to mortgage lending. One embodiment includes a system and method of detecting and assessing risks including fraud risks, early payment default risks, and risks related to fraudulently stated income on loan applications. One embodiment includes a computerized method that includes creating a combined risk detection model based on a plurality of risk detection models and using the combined risk detection model to evaluate loan application data and generate a combined risk score that takes into account interaction of different types of risks individually and collectively detected by the plurality of risk detection models.

12. A computerized method of detecting and assessing mortgage lending risks, the method comprising:
-
receiving, on a physical computer processor, mortgage transaction data that includes loan application data and historical transactions data; determining, on a physical computer processor, combinability of a plurality of risk detection models, the determining comprising determining predictive performance of scores from one or more combinations of the risk detection models as compared to the historical transactions data, wherein the plurality of risk detection models further comprise two or more of; a first risk detection model configured to generate a first risk model score that is indicative of the presence of a first risk in the loan application data; a second risk detection model configured to generate a second risk model score that is indicative of the presence of a second risk in the loan application data;
ora third risk detection model configured to generate a third risk model score that is indicative of the presence of a third risk in the loan application data, wherein the first risk, the second risk, and the third risk are different risks; extracting, on a physical computer processor, input features from the risk detection models that are determined to be combinable, the input features created from a mathematical combination of the scores and additional data, wherein the input features are extracted from the two or more risk detection models by mathematically combining scores from the plurality of risk detection models for input into a combined risk detection model, the input features being selected as based at least in part on a comparison of the predictive performance of the plurality of risk detection models and a selection of a modeling method used to construct the combined risk detection model; applying, on a physical computer processor, the combined risk detection model to the mortgage transaction data to generate a composite risk score, wherein the combined risk detection model is configured to receive the extracted input features from the plurality of risk detection models determined to be combinable and mortgage transaction data not output by the risk detection models, the extracted input features further being selected as based at least in part on a modeling method used to construct the combined risk detection model; and generating, on a physical computer processor, a report including the composite risk score generated by the combined risk detection model. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
