Title: Risk visualization: When actuarial science meets visual analytics

Abstract
Actuarial Science aims at measuring and modeling financial risk with the use of statistical and mathematical models. Unlike traditional sciences like Physics or Biology, its main raw material, risk, is not directly observable and inherently subjective. It is perhaps for some of those reasons that the concept of risk visualization has not received much attention in the Literature. This paper argues that risk visualization can find many practical applications in finance and insurance, namely for communicating about risk (internally, toward the senior management or third parties), risk identification and management (through comprehensive, real-time, interactive Risk Dashboard) and informed decision making (multi-objective optimization). After reviewing the foundations of visual analytics and its appeal for risk analysis and risk management, applications of dimensionality reduction and clustering techniques to practical problems of risk monitoring in finance and insurance are presented.
