We propose a coherent framework using support vector regression (SRV) for generating and ranking a set of high quality models for predicting emerging market sovereign credit spreads. Our framework adapts a global optimization algorithm employing an hv-block cross-validation metric, pertinent for...

The accurate forecasting of short-term load for urban gas is the premise of gas supply sales, pipe network planning, and energy optimization scheduling. This paper adopts a hybrid model that integrates the fruit fly optimization algorithm (FFOA), simulated annealing algorithm (SA), cross factor...

Housing prices in many countries have increased significantly over the past years, fueling a fear that speculative price bubbles will return. However, it can be difficult for policymakers to recognize when regulatory interventions in the market are necessary to counteract bubbles. This report...

„Wir glauben, der Siegeszug der digitalen Technik habe innerhalb weniger Jahre alles revolutioniert: unsere Beziehungen, unsere Arbeit, die Demokratie. Aber jetzt dreht der Soziologe Armin Nassehi den Spieß um und zeigt, dass es immer schon technische Revolutionen gab. Nicht die...
