Motif Extraction: Normalization of Scores
نویسنده
چکیده
This paper examines a method to normalize a score of a stochastic motif, represented by a hidden Markov model (HMM). The accuracy of the Z score method, which is one of the score normalization method, is compared with that of the whole search method.

For the paper “ Localized Motif Discovery in Gene Regulatory Sequences ”
LocalMotif uses a combination of three different scoring functions which individually describe three different characteristics of a motif. The relative entropy score (RES) measures the degree of surprise in the motif nucleotide pattern with respect to the background distribution of nucleotides. The over-representation score (ORS) measures the overabundance of the number of instances of the moti...

Objective(s): Alternative normalization methods were proposed to solve the biased information of SPM in the study of neurodegenerative disease. The objective of this study was to determine the most suitable count normalization method for SPM analysis of a neurodegenerative disease based on the results of different count normalization methods applied on a prepared digital phantom similar to one ...
متن کاملThe genetics of gene expression: comparison of linkage scans using two phenotype normalization methods
The goal of this paper is to investigate the effects of normalization procedures for expression data on linkage results. We selected the two most commonly used expression data extraction and normalization methods, Affymetrix global scaling and dChip invariant. After applying these two methods in 3554 expression phenotypes, we identified 45 phenotypes that were more likely to be genetic for eith...
متن کاملNormalization of Parents’ Response to Children’s Positive Emotions Scale
Abstract This study evaluated the normalization of the Persian version of the Parents’ Response to Children’s Positive Emotions Scale (PRCPS). For evaluating reliability and validity of this scale through random sampling, 400 mothers of 4-7-year-old children completed the PRCPS and Cognitive Emotion Regulation Questionnaire (CERQ). Evaluating internal reliability of PRCPS subscales by Cronba...
متن کاملHITSZ_CDR System for Disease and Chemical Named Entity Recognition and Relation Extraction
In this paper, an end-to-end machine learning-based system was proposed for the challenge task of chemical and disease named entity recognition (DNER) and chemical-induced diseases (CID) relation extraction in BioCreative V, where DNER includes chemical and disease mention recognition (CDMR) and normalization (CDN). The system consists of six components: a preprocessing module, two individual s...
