Credit and Profit Scoring in Peer-to-peer (p2p) Lending: Techniques, Challenges, and Proposed Solutions
Traditional peer-to-peer (P2P) lending decision support systems tend to focus on credit scoring. Credit scoring is formulated as a classification problem where the response variable is a binary variable assigning “0” to failed loans and “1” to non-failed loans. Various machine learning techniques can be used to solve the above problem by predicting the borrower’s probability of default. However, the loan default probability cannot assess the profit that the loan is likely to yield. Hence, there is a need for a scoring approach focusing on a profitability index as its output. This type of analysis is known as profit scoring, and aims to identify the most profitable borrowers. Recent studies have explored the utility of profit scoring over credit scoring in P2P lending decision support systems. This talk provides: (1) A review of the existing credit and profit scoring techniques (2) A detailed discussion on the challenges of these systems. (3) A novel profit scoring technique is developed to overcome the challenges with the existing systems. The proposed technique is a two-stage model based on machine learning algorithms. (4) A case study using real data from the Lending Club (one of the largest U.S. P2P lending platforms).

Innovation in Forecasting the Impact of Price Changes Across a Large Portfolio of Products with Application to the Food Service Industry
In this session, Erik will share an innovative approach to the problem of modeling the effect of price changes on a large portfolio of products which includes both complements and substitutes. The approach sidesteps the data difficulties inherent in such large-scale projects through leveraging the most efficient statistical techniques. This is joint work with Dr. Frederic Puech.
The method consists of three stages:
1. First, a prediction model for each product is developed using only information for that product. In the scenario for which this method was designed, this type of simple model was necessary because of massive multicollinearity in the data. The model that was used originally was a combination of time series and regression methods, but different situations may call for different models at this stage.
2. The second stage is an analysis of the substitution patterns between products. This can take the form of a nesting structure which may be obtained by several different methods. The direct effect of a price change on a product will affect the sales of substitute products via the nesting structure.
3. The third stage involves finding the conditional probabilities of purchase between complementary products. This was accomplished using standard data mining techniques. The change in volume of the sales of products from stage two affects the sales of the complementary products via the conditional probabilities.
These three stages form a framework for building a predictive model in any situation that involves a large portfolio of products with possibly complex interactions. This approach can handle data difficulties like multicollinearity that would preclude the use of multinomial logit or econometric models.
Erik will demonstrate an implementation of the model, developed for a recent project, which uncovered several million dollars in incremental revenue for a large US company in the foodservice industry. Erik will also show how the approach can be applied to other industries.

A Multidisciplinary Analytics Effort to Support Public Health Policies Against Cervical Cancer Epidemics in Colombia
Cervical cancer (CC) is the fourth death cause by cancer in women worldwide. Developing countries bear the highest load in terms of incidence, prevalence and death rate, and Colombia is not an exception. According to the Colombian Ministry of Health, CC is the second death cause by cancer among women, and the first one for women between 15 and 44 years of age. The standardized death rate (deaths per 100,000 women) is around 8, over 3 times that of the USA. Encouragingly, the etiology of CC is much better understood than that of other cancer types. CC has an assigned cause: 99% of cases are due to the cell malignancies induced by sexually transmitted Human Papilloma Virus (HPV) infections. Moreover, when treated in early stages, CC is easily eradicated. These facts open leeway for contrast actions, such as HPV vaccination, screening tests and educational campaigns. Quantifying the cost-effectiveness of interventions is of paramount importance to define public health policies, particularly in a developing country such as Colombia, with limited resource availability. Though, the effects of CC contrast actions are only visible in the long-term. Therefore, evaluating interventions requires an ability to generate reliable predictions about the dynamics of the Colombian population´s (48.2 million people, 2016 estimate) health state. Also, it entails challenging Analytics efforts, where diverse data sources (biological, clinical, socio-economical) and multiple modeling views (demographics, epidemics, social, public health) need to be integrated for a proper quantification of interventions impacts. This paper describes an ambitious multi-disciplinary and on-going project. A team of Colombian researchers with expertise in medicine, engineering and public health from both academia and public research institutions are joining efforts with the objective of designing and implementing a data-driven computational tool to assist decision-makers in shaping national public health policies. To this aim, we are employing and integrating into a coherent framework multiple Analytics techniques. We are developing a descriptive, predictive and prescriptive solution that, for a given set of resource constraints, determines the time-dependent deployment of CC contrast interventions that turns up in the best predicted results for the Colombian population. This research endeavor brings in numerous challenges. It requires acquiring and modeling data to characterize population dynamics, HPV infection epidemics, the progression from pre-cancerous to the advanced stages of CC lesions, patient preferences and the specificity and sensitivity of screening examinations. Furthermore, it is necessary to consider the expected costs and savings for the health system and the citizens, keeping in mind the social costs of the disease and the uncertainties brought in by the post conflict rearrangements in the country. Valid predictive models must be in place to properly estimate the number of individuals in different age ranges for the growing Colombian population, to project the HPV infection spread among women of different ages, regions and socio-economic strata, and to calculate the expected incidence, prevalence and death rate due to CC over long-term horizons. Finally, complex optimization problems must be solved to complete the prescriptive step and provide the decision-makers with effective interventions roadmaps.
