Statistical Methods and Machine Learning Techniques for Insurance and Risk Management Data Analytics

Dear Colleagues,

Risk and Insurance disciplines are facing a new era of big data analytics. This has taken multiple forms such as the growing desire to analyze individual claims records in large claims portfolios, analysis of large collections of consumer surveys and consumer preferences for insurance products (consumer analytics), telematics and usage based insurance, catastrophe modelling, weather monitoring and insurance, demographic and mortality data and large portfolios of annuities, to name but a few examples. A common theme in all of these cases is the importance of extraction of salient features, these are features that best summarize vast and complex structured data records in a manner that is more amenable to modelling and computational tasks such as those commonly identified as core to machine learning, statistics and data analytics found in settings, such as supervised machine learning, unsupervised learning, reinforcement learning, and offline and online learning environments. Extraction approaches to capture salient representations of the data, classically referred to in statistics as model summaries or sufficient and summary statistics and are presently referred to in a broader sense in machine learning as feature extraction is an important emerging challenge in insurance and risk management.

This Special Issue aims to bring together papers that tackle the challenge of innovative new machine learning and computational statistical methods for feature extraction in insurance and risk management settings that can tackle issues in such data records related to issues such as the sheer size and number of records, mixed types of structures such as video, audio, sensor observations (e.g. LIDAR, weather sensors, seismic sensors, bathimetry sensors, GPS, etc.) time-series, panel, longitudinal, survey, topological, graphical, matrix and tabular valued data records that need to be combined for modelling purposes in modern risk and insurance settings. Furthermore, issues to do with missing data and noise/outliers/miss reporting, etc., are required to be addressed in such large records. It is therefore the aim of this Special Issue to bring together collections of theoretical, methodological and practical papers all tackling a common theme that revolves around the development of robust and computationally efficient methodologies and computational approaches to feature extraction in risk and insurance settings tackling the issues just identified. Such features extraction methods should be developed with the intention for the features to then be amenable to statistical modelling tasks, such as classification, regression, clustering, dimensionality reduction, semi-supervised learning and reinforcement learning, to name but a few of the possible tasks such features should be suitable for.

Therefore, the scope of the Special Issue is to propose methodologies, computational approaches and statistical analysis of existing approaches from machine learning and computational statistics that are explored and justified in development of potentially important feature extraction methodologies in insurance and risk management settings. All papers in this Special Issue must focus the development of such methodologies and approaches within a particular specific discipline of insurance or risk management, which must first be explained in detail before development of the methods. If possible, further motivations of the proposed methods should be provided either through theoretical justifications based on existing approaches classically adopted and how the new methods will relate or enhance/improve classical approaches or through a detailed and thorough investigation of real data applications. If the latter is considered, we as that the authors provide all code and data (in sanitized form, in an open access public repository for the purpose of reproducible science).
