Comparative Analysis of Splice Site Regions by Information Content
We have applied concepts from information theory for a comparative analysis of donor (gt) and acceptor (ag) splice site regions in the genes of five different organisms by calculating their mutual information content (relative entropy) over a selected block of nucleotides. A similar pattern that the information content decreases as the block size increases was observed for both regions in all t...
متن کاملFeature subset selection for splice site prediction
MOTIVATION The large amount of available annotated Arabidopsis thaliana sequences allows the induction of splice site prediction models with supervised learning algorithms (see Haussler (1998) for a review and references). These algorithms need information sources or features from which the models can be computed. For splice site prediction, the features we consider in this study are the presen...
متن کاملChromatic Information and Feature Detection in Fast Visual Analysis
The visual system is able to recognize a scene based on a sketch made of very simple features. This ability is likely crucial for survival, when fast image recognition is necessary, and it is believed that a primal sketch is extracted very early in the visual processing. Such highly simplified representations can be sufficient for accurate object discrimination, but an open question is the role...
متن کاملInformation analysis of human splice site mutations.
Splice site nucleotide substitutions can be analyzed by comparing the individual information contents (Ri, bits) of the normal and variant splice junction sequences [Rogan and Schneider, 1995]. In the present study, we related splicing abnormalities to changes in Ri values of 111 previously reported splice site substitutions in 41 different genes. Mutant donor and acceptor sites have significan...
متن کاملFast feature selection using a simple estimation of distribution algorithm: a case study on splice site prediction
MOTIVATION Feature subset selection is an important preprocessing step for classification. In biology, where structures or processes are described by a large number of features, the elimination of irrelevant and redundant information in a reasonable amount of time has a number of advantages. It enables the classification system to achieve good or even better solutions with a restricted subset o...
