In this paper, we approach, using neural computation and ensemble systems, a pattern classification problem in fluorescence spectrometry, the resolution of difficult multi-fungicide mixtures (overlapping), specifically the benzimidazole fungicides, benomyl, carbendazim, thiabendazole and fuberidazole. These fungicides are compounds of an important environmental interest. Because of this, from an analytical point of view, it is interesting to develop sensitive, selective and simple methods for their determination. Fluorescence spectrometry has proven to be a sensitive and selective technique for determination of many compounds of environmental interest, but in some cases it is not enough. HUMANN is a hierarchical, unsupervised, modular, adaptive neural net with high biological plausibility, which has shown to be suitable for identification of these fungicides and organochlorinated compounds of environmental interest. We propose two modular artificial intelligent systems, with a structure of pre-processing and processing stage, a multi-input HUMANN-based system, using multi-fluorescence spectra as input to the system, and a HUMANN-ensemble system. We analyze the optimal configuration of inputs and the ensemble in order to obtain better results. We study such figures as precision and sensitivity of the method. Our proposal is a smart, flexible and effective complementary method, which allows reducing the analytical and/or computational complexity of the analysis.

This review covers the approximately two-year period since our last review (A1), roughly from November 1997 through October 1999. A computer search of Chemical Abstracts provided most of the references for this review. Coverage is limited to articles that describe new developments in the theory and practice of molecular luminescence for chemical analysis in the ultravioletvisible and near-infrared region.Citations may be duplicated between sections due to articles with contents that span several topics. However, in an effort to reduce the length of this review, we have tried to limit this kind of duplication. In general, citations are limited to journal articles and usually do not include patents, proceedings, reports, and dissertations.This review is considerably shorter than previous reviews. This is because we have tried to focus on important advances of general interest and relevance to the field of analytical chemistry rather than extensions of previous advances. This reduction was done at the request of the journal editor in an attempt to significantly reduce the length of the biannual reviews. We have also expanded
