1 Harnessing Predictive Analytics to Improve Customer Data Analysis and Reduce Fraud Patrick Shearman General Manager, Information Management HCF of Australia Ltd Technology and Innovation for Insurance March 2007

2 Introduction What is Predictive Analytics? Targeting individuals customers more effectively Streamlining, simplifying and accelerating data analysis An overview of some techniques used in fraud detection Strengths and weakness Conclusion

3 What is Predictive Analytics? Originated in statistical related research studies Predictive Analytics Advanced Analytics Statistics Data Mining Text Mining Data Visualisation Reporting Decision Optimisation Rules Engine Scoring Engine Looking for patterns of behaviour within historical data BI analysts use the output in conjunction with traditional analytical techniques

7 Modelling Techniques C5.0 example Models which are mathematical equations that describe the relationship among a set of data. Models have been built to predict member attrition, product up-sell and fraud. C5.0 algorithm also produces a set of rules that tries to make predictions for individual customers. C5.0 attaches a probability of a particular behaviour occurring ranging between 0 (will never occur) and 1 (will definitely occur). C5.0 models work well even in the presence of problems such as missing data and large numbers of input fields. In addition, C5.0 models tend to be easier to understand than some other model types, since the rules derived from the model have a relatively straightforward interpretation

8 Modelling Techniques C5.0 example Migration Analysis to analyse the natural product migrations of HCF members over the past two years. Predictive modelling to select product migration that provide high increases in premium and target members most likely to make those migrations in the near future. Years of transactional data Scoring & Strategies Predict Up-Sell 2 Years 3 Months 6 Months DATA VARIABLES Timing of upgrades Length of Membership Single vs. Family scale (children vs. empty nesters) Claims history for both hospital and extras Per Night Excess or co-payments Payment methods and frequency Highest level of Rebate entitlements Age of contributor (and dependents) Last product movement Life-time health cover loading Health Premium $ Demographic data

9 Rules for 1 - contains 18 rule(s) Predictive Analytics Modelling Techniques C5.0 example Rule 1 for 1 (51; 0.981) if LHC_LOADING_CHGE_FLAG = 1 then 1 Rule 2 for 1 (22; 0.958) Customers in Segment Probability of buying product if AGE <= 37 and NEW_SEGMENT = JC and PEEK_EXCESS_PROD = 0 and MODALITY_O_OOP_Count <= 1 and CLAIM_MONTHS > 4 then 1 Rule 3 for 1 (201; 0.946)

10 Modelling Techniques C5.0 example From the Gains Chart it can be seen that 60% of those customers most likely to respond will be achieved in the first 10% of customers mailed, compared to about 10% if data mining was not used. More important than the Gains Chart is the Response Chart which indicates a response of rate of 3% if we mailed the first 10% of customers. The response rate is much higher than the baseline response rate of about 0.5% which one would get without data mining.

14 Targeting individuals customers more effectively Summary Can lead to a better understanding of your customer needs Integrated environment to drive interactions across all channels (inbound and outbound) Based on preferences, needs and risks of individual customers (Advanced Analytics) Determine the optimal contact mix of product, channel and time (Decision Optimization) Leverage of existing BI architecture Develops business rules around customer segments

16 Fraud Detection Analyze claims payment patterns of behaviour Customer Provider Staff Detection of inappropriate practice Using automation and data mining techniques Develop business rules to automate a monitoring process

17 Modelling Techniques for fraud detection Is the classification of objects into different subsets of data (clusters), so that the data in each subset (ideally) share some common trait Models which are mathematical equations that describe the relationship among a set of data. Highlights anomalies in the patterns of behaviour Data visualization C5.0 algorithm also produces a set of rules that tries to make predictions for individual clients. C5.0 attaches a probability of a particular behaviour occurring ranging between 0 (will never occur) and 1 (will definitely occur). C5.0 models work well even with missing data and large numbers of input fields, minimal model training times and easier to understand than some other model types, with rules relatively straightforward to interpret.

18 Fraud Model Clustering 3,121,842 Cases for 2 years data and 11 clusters

19 Fraud Model Anomaly 209,149 records in the cluster with 2,532 Anomalies (1.2%) Variables

20 Fraud Model Data visualisation Distinct Clustering Indistinct Clustering Anomalous Clustering Anomaly

21 Fraud Predictive Analytics Summary Automates the fraud detection process Provides profiles of customer and provider claiming patterns Detects anomalies or patterns of behaviour differing from the norm Identifies staff, customer and provider risks Helps build business rules around inappropriate practices

22 Conclusion - Strengths Simplifies the actuarial analysis process Uses proven statistical methodology Adds value to the overall business intelligence framework Gives better understanding of customers and helps target the right customers Challenges peoples current perceptions about a subject Develops business rules and models which can be integrated into systems architecture

23 Conclusion - Weakness Expensive Models can be high maintenance Can get complex Data preparation can be time consuming Results abstract and difficult to interpret May not discover anything new Return on investment can be marginal
