From AI and Data Science back to Operations Research and Financial Modeling

Abstract: Financial organizations require various quantitative tools to reduce the complexity of the quantitative decision process - especially in the age of Big Data. The recent AI hype led many people to believe that a responsible mathematical modeling of the underlying (financial and economical) problems can be safely outsourced to machines. One has to be forgiving because through Social Media and other non-peer-reviewed media channels Artificial Intelligence (AI) promised to change the world (once again). Data Scientists who integrate AI methods into business processes are one of the most sought-after group of experts at the moment - regardless whether they understand the thematic challenge or not. Within the last few years classical Machine Learning technologies which were around for at least 20-30 years regained enormous popularity due to fascinating applications which are facilitated by Deep Learning which is based on Artificial Neural Networks. The hugely increased computing power especially due to the availability of GPUs allows for massively deep Neural Networks being fit to Big Data problems. However there are actually two main types of AI problems. The first one includes Robotics, Industry 4.0 and Internet of Things (IoT) and considers technological elements which basically either work or fail. The second one is concerned with erratic structures like humans (customers, clients, employees, ...), financial markets and meteorological data. Consider a simple but telling example where the same human customer might behave differently in the morning and in the afternoon due to how lunchtime was perceived which makes it difficult to use plain pattern-matching methods. In this lecture we contrast these two areas and show that in the area of Robotics a rather plain machine-only, self-learning AI approach might be successful while in the other one - which is extremely important for the whole field of Banking and Finance - the emphasis has to be put on human creativity when applying AI technologies. In the latter case methods of Operations Research, Econometrics and other mathematical sound approaches to solving quantitative decision problems have shown to be of much more use by cleverly integrating Human Intelligence into the modeling process. It is time to renew the fascination of Computational Management Science without using AI jargon - this talk aims to provide some relevant pointers to use for this talk.

The Mathematics of Ageing

Abstract: Age is a crucial variable in social sciences and particularly in population dynamics. In the first part of this paper, a two-state optimal control model is proposed to explain the substantial variations of scientific production over the life cycle of researchers. We identify conditions under which typical hump-shaped age-specific´patterns of scientific production turn out to be optimal for individual researchers. The second part of the paper deals with the ageing of learned societies. In a nutshell, the dilemma of a learned society is that keeping young, i.e. electing young entrants, has the drawback of reducing the replacement rate of members. It turns out that electing a mix of young and old members delivers the optimal solution of the problem, i.e. guaranteeing a young age structure, while ensuring a high recruitment rate.
