The regular array of distally pointing hairs on the mature Drosophila wing is evidence for the fine control of Planar Cell Polarity (PCP) during wing development. Normal wing PCP requires both the Frizzled (Fz) PCP pathway and the Fat/Dachsous (Ft/Ds) pathway, although the functional relationship between these pathways remains under debate. There is strong… (More)
Empirical modelling in high dimensional spaces is usually preceded by a feature selection stage. Irrelevant or noisy features unnecessarily increase the complexity of the problem and can degrade modelling performance. Here, multiobjective genetic algorithms are proposed as effective means of evolving a diverse population of alternative feature sets with… (More)
This paper discusses developments in international standards (ISO) for metadata that can be used to denote languages, the ISO 639 series of standards. These developments are intended to support improvements in the reusability and interoperability of data and provide for future generations of language resources and technologies. The focus of the paper is on… (More)
The tuning algorithm is selected based on robustness and ease of application and is described along with the requirements of the software and hardware.
Several subspace algorithms for the identification of bilinear systems have been proposed recently. A key practical problem with all of these is the very large size of the data-based matrices which must be constructed in order to 'linearise' the problem and allow parameter estimation essentially by regression. Another shortcoming of currently known subspace… (More)
