Sophisticated vs. Simple Systemic Risk Measures

Simple vs. Sophisticated Approaches for Patent Prior-Art Search

Patent prior-art search is concerned with finding all filed patents relevant to a given patent application. We report a comparison between two search approaches representing the state-of-the-art in patent prior-art search. The first approach uses simple and straightforward information retrieval (IR) techniques, while the second uses much more sophisticated techniques which try to model the step...

Measures of Systemic Risk

Systemic risk measures: the simpler the better?

The financial system plays a fundamental role in the global economy as the middleman between agents who need to borrow and agents who are willing to lend or invest. As a consequence, it is naturally linked to all economic sectors and, therefore, if the financial system does not work properly, its problems have a strong impact on the real economy.

Systemic Risk Evaluation of Banks and financial institutions applying Markov clustering method and centrality measures of risk

Systemic risk is the risk beared by an economic system because of a special organization. This means that a liquidity problem or a financial crisis in one company could trigger a chain of reactions that puts the whole market into trouble. This kind of risk was underestimated until 2008 financial crisis. Now federal regulations exist for controlling this risk of financial institutions. Among div...

From Simple Features to Sophisticated Evaluation Functions

This paper discusses a practical framework for the semi{ automatic construction of evaluation functions for games. Based on a structured evaluation function representation, a procedure for exploring the feature space is presented that is able to discover new features in a computational feasible way. Besides the theoretical aspects, related practical issues such as the generation of training pos...
