The Santa Fe Institute’s economics program has nurtured some of the discipline’s most highly innovative forml theorizing and interdisciplinary brainstorming since its inception in the late 1980s. This proceedings volume provides the occasion for a review of ten-year’s progress by researchers associated with the Institute. The initial programmatic proposals of the first volume have indeed ben fl...

Central and Eastern Europe countries are in the political and economic transitional process of merging with the European Union. How has foreign investment already transformed these countries’ economic sectors and how will it affect the national economies in terms of capitalization across economic sectors in the near future? Our prime consideration is portfolio investment impact on the dynamics ...

The goal of this work is to introduce one of the most successful among recently developed statistical techniques – the support vector machine (SVM) – to the field of corporate bankruptcy analysis. The main emphasis is done on implementing SVMs for analysing predictors in the form of financial ratios. A method is proposed of adapting SVMs to default probability estimation. A survey of practicall...

Technical traders base their analysis on the premise that the patterns in market prices are assumed to recur in the future, and thus, these patterns can be used for predictive purposes. This paper uses the daily Dow Jones Industrial Average Index from 1897 to 1988 to examine the linear and nonlinear predictability of stock market returns with simple technical trading rules. The nonlinear specif...

This article explores the explicative capabilities of neural network classifiers with automatic relevance determination weight regularization, and reports the findings from applying these networks for personal injury protection automobile insurance claim fraud detection. The automatic relevance determination objective function scheme provides us with a way to determine which inputs are most inf...

We construct an arti cial neural network to act as a system of leading indicators. We focus on radial basis functions as the architecture and forward selection as the method for determining the number of basis functions in the network. A brief review is given of the advantages of this as a strategy. Using common heuristics to determine scaling, radii and centre population, we nd that the result...

Regression and neural network models of wage determination are constructed where the explanatory variables include detailed information about the impact of school curricula on future earnings. It is established that there are strong nonlinearities and interaction effects present in the relationship between curriculum and earnings. The results have important implications in the context of the hu...

Original scientific paper In this paper, influence of flame spraying and fusing on microstructure of substrates made from heat treated carbon steel C45, a heat treated low alloyed 42CrMo4 steel and stainless austenitic steel X6CrNiMo18-10-2, has been investigated. Flame spraying and fusing is a deposition technique commonly applied to nickel-base self-fluxing alloys (NiCrBSi alloys). Because of...
