Matched filter for signature extraction in bioinformatics data set

In many bioinformatics research and applications, we need to extract interesting signals or to compare between signals in large multivariate data sets. In most cases those signals are buried in “noise”. Finding methods to increase signal-to-noise ratio is an important statistical problem studied for many years and there exist a set of well developed methods for noise reduction and signal boosti...

Genetic Algorithm-neural Network: Feature Extraction for Bioinformatics Data

With the advance of gene expression data in the bioinformatics field, the questions which frequently arise, for both computer and medical scientists, are which genes are significantly involved in discriminating cancer classes and which genes are significant with respect to a specific cancer pathology. Numerous computational analysis models have been developed to identify informative genes from ...

Answer Sets Programs for Querying Inconsistent Databases: The Consistency Extractor System

The Consistency Extractor System (ConsEx) is a general implementation of consistent query answering, i.e. the computation of consistent answers to queries posed to databases that may fail to satisfy certain desirable integrity constraints. The system is based on the specification of the repairs of the original instance as the stable models of disjunctive logic programs (aka. answer set programs...

The consistency extractor system: Answer set programs for consistent query answering in databases

We describe theConsistency Extractor System (ConsEx) that computes consistent answers to Datalog queries with negation posed to relational databases that may be inconsistent with respect to certain integrity constraints. In order to solve this task, ConsEx uses answers set programming. More precisely, ConsEx uses disjunctive logic programs with stable models semantics to specify and reason with...
