An Improved Model for Gene Cluster Inference
نویسندگان
چکیده
Inferring functionally related genes in microbial genomes is an important problem, which has been addressed by various gene cluster detection methods. Existing models well capture genomic inversions, gene duplications and insertions across a pair of genomic regions. Clusters involving multiple regions are indirectly inferred through constituent pairs. In this paper, we improve upon current work by a) formally modeling gene losses, and b) directly inferring gene clusters comprising of multiple genomic regions. Our preliminary results show a better sensitivity and specificity in identifying verified operons when compared with HomologyTeams model. Keywords-comparative genomics, gene clusters, gene teams

New Approach for Customer Clustering by Integrating the LRFM Model and Fuzzy Inference System
This study aimed at providing a systematic method to analyze the characteristics of customers’ purchasing behavior in order to improve the performance of customer relationship management system. For this purpose, the improved model of LRFM (including Length, Recency, Frequency, and Monetary indices) was utilized which is now a more common model than the basic RFM model apt for analyzing the cus...
متن کاملAn Efficient Cluster Head Selection Algorithm for Wireless Sensor Networks Using Fuzzy Inference Systems
An efficient cluster head selection algorithm in wireless sensor networks is proposed in this paper. The implementation of the proposed algorithm can improve energy which allows the structured representation of a network topology. According to the residual energy, number of the neighbors, and the centrality of each node, the algorithm uses Fuzzy Inference Systems to select cluster head. The alg...
متن کاملPredicting Survival of Patients with Lung Cancer Using Improved Adaptive Neuro-Fuzzy Inference System
Introduction: Lung cancer is the main cause of mortality in both genders worldwide. This disease is caused by the uncontrollable growth and development of cells in both or one of the lungs. Although the early diagnosis of this cancer is not an easy task, the earlier it is diagnosed, the higher will be the chance of treating. The objective of this study was to develop an optimized prediction mod...

متن کاملStudy on phylogenetic status of Hari barbel Luciobarbus conocephalus (Kessler, 1872) from Hari river using Cytb gene
Recently, Luciobarbus conocephalus from the Hari River was reported for the first time, but there is doubt about the validity of this species between authors, because some of them placed it as a subspecies or synonym of L. capito. Therefore, the present study was conducted to investigate the status of phylogeny and the validity of this species. For this purpose, specimens captured from Hari Riv...
متن کاملBayesian Inference for Spatial Beta Generalized Linear Mixed Models
In some applications, the response variable assumes values in the unit interval. The standard linear regression model is not appropriate for modelling this type of data because the normality assumption is not met. Alternatively, the beta regression model has been introduced to analyze such observations. A beta distribution represents a flexible density family on (0, 1) interval that covers symm...
