This special issue of JCIF focuses on a narrower scope: the theories, methods and algorithms for mapping financial data from its original representation into another form with reduced complexity and/or dimensionality that appear beneficial to financial applications. Of particular interest are techniques which can serve as preprocessors to data-driven models and data mining technologies, including those which address or utilize one or more of the following: complexity and dimensionality characterization, identification and analysis; data compression; feature extraction techniques; regularity discovery; inductive reasoning; randomness tests; algorithmic entropy; informational distance; minimal description length; adaptive and nonlinear PCA and other alternatives to standard forms of linear PCA; finite sequence statistics; variable combining methods; data filtering; categorical versus continuously- valued inputs; high-dimensional visualization analysis; and input space reduction techniques. MOTIVATION In finance, we inevitably encounter an unavoidable dilemma: an interest in collecting and utilizing as much data as possible in its original form so that potentially useful information is not lost, although this often results in data with high complexity and/or dimensionality that increases costs and reduces performance. Despite this, the notion that more input data is better persists. The need for managing complexity and dimensionality arises from eroding profit margins, diminishing arbitrage opportunities, lowered barriers to entry, increasingly segmented markets, increased costs, and, in general, the reduced performance (e.g., generalization ability) of tools applied, such as data-driven models and data mining technologies. Thus, the topic of this special issue represents very important areas of applied research across multiple disciplines relevant to computational intelligence in finance.
