Several metrics were applied both on the optimal decision point and along the continuous output domain.The statistical tests showed that multilayer perceptrons perform better than logistic regression at 95% confidence level, for all the metrics used.","PeriodicalId":74516,"journal":{"name":"Proceedings of the ...

Humans, with the massive computational power of the cerebral cortex, have managed to solve most of the problems that make pattern recognition such a difficult task. Other animals are not so well endowed with processing power: an insect brain, for example, has 105 to 106 neurons compared with our 1011. Nevertheless, they still have to recognise predators, prey and conspecifics, and find their way around the world. Often this means that they have to cut corners, using what machinery they have in economical ways. Typically this means tailoring their recognition systems to just those features that really matter, rather than going for the general purpose mechanism that primates have achieved. In this talk I will examine some of the ingenious and sometimes strange solutions that animals such as insects, spiders, crabs and molluscs have come up with to simplify the tasks of pattern recognition, while still satisfying their requirements of their often complex behaviour.","PeriodicalId":74516,"journal":{"name":"Proceedings of the ...

Based on the analysis of at least two pixel-synchronous images of the scene under different illumination conditions, this framework combines a shape from shading approach for estimating surface gradients and altitude variations with a shadow analysis that allows for an accurate determination of altitude differences on the surface. As a first step, the result of shadow analysis is used for selecting a consistent solution of the shape from shading reconstruction algorithm. As a second step, an additional error term derived from the fine structure of the shadow is incorporated into the reconstruction algorithm. This framework is applied to three-dimensional reconstruction of regions on the lunar surface using ground based CCD images. Beyond the planetary science scenario, it is applicable to classical machine vision tasks such as surface inspection in the context of industrial quality control.","PeriodicalId":74516,"journal":{"name":"Proceedings of the ...

Given a (typically reduced) set of initial string prototypes and a training set, it iteratively updates prototypes to better discriminate training samples. The update rule, which is based on the edit distance, adjusts a prototype by removing those local differences which are both frequent with respect to same-class closer training strings and infrequent with respect to different-class closer training strings. Closer training strings are defined by unsupervised clustering. The process continues until prototypes converge. Its main innovation is to provide a non-random local update rule to “move” a string prototype towards a number of string samples. A series of learning/classification experiments show a better 1-np performance of the updated prototypes with respect to the initial ones, that were originally selected to guarantee a good classification.","PeriodicalId":74516,"journal":{"name":"Proceedings of the ...

Tokens close by their morphology and confirmed in their location within different similar contexts make apparent some parts of speech representative of the structure elements. This bottom up approach avoids the use of an priori knowledge provided that there are redundant and frequent contexts in the text. The approach is applied on the invoice body text roughly recognized by OCR and automatically segmented. The method makes possible the detection of the invoice articles and their different fields. The regularity of the article composition and its redundancy in the invoice is a good help for its structure. The recognition rate of 276 invoices and 1704 articles, is over than 91.02% for articles and 92.56% for fields.","PeriodicalId":74516,"journal":{"name":"Proceedings of the ...
