Thesis working title

Predictive modelling in insurance

The increasing popularity of Big Data Analytics is revolutionising the risk modelling (and thus premium pricing strategies) of the insurance industry. Instead of using traditional methods that rely on proxies in risk modelling, premium prices can be ‘tailor-made’ for policy holders based on individual attributes. However, valuable information is often hidden behind data that are noisy, volatile and massive in dimensionality and size. The aim of this research is to provide novel tools for practitioners in extracting relevant information from the voluminous data for premium pricing through machine learning and optimisation algorithms.
