Biclustering expression data based on expanding localized substructures
Erten, Cesim; Sözdinler, Melih (Springer-Verlag Berlin Heidelberg, 2009)Biclustering gene expression data is the problem of extracting submatrices of genes and conditions exhibiting significant correlation across both the rows and the columns of a data matrix of expression values. We provide ... -
Colored simultaneous geometric embeddings
Brandes, Ulrik; Erten, Cesim; Fowler, J. Joseph; Frati, Fabrizio; Geyer, Markus; Gutwenger, Carsten; Hong, Seok-Hee; Kaufmann, Michael; Kobourov, Stephen G.; Liotta, Giuseppe; Mutzel, Petra; Symvonis, Antonios (Springer-Verlag Berlin, 2007)We introduce the concept of colored simultaneous geometric embeddings as a generalization of simultaneous graph embeddings with and without mapping. We show that there exists a universal pointset of size n for paths colored ... -
Crossing minimization in weighted bipartite graphs
Çakıroğlu, Olca Arda; Erten, Cesim; Karataş, Ömer; Sözdinler, Melih (Springer, 2007)Given a bipartite graph G = (L-0, L-1, E) and a fixed ordering of the nodes in L-0, the problem of finding an ordering of the nodes in L-1 that minimizes the number of crossings has received much attention in literature. ... -
Force-directed approaches to sensor localization
Efrat, Alon; Forrester, David; Iyer, Anand; Kobourov, Stephen G.; Erten, Cesim (SIAM, 2006)We consider the centralized, anchor-free sensor localization problem. We consider the case where the sensor network reports range information and the case where in addition to the range, we also have angular information ... -
Fully decentralized, collaborative multilateration primitives for uniquely localizing WSNs
Çakıroğlu, Olca Arda; Erten, Cesim (Springer-Verlag Berlin, 2009)We provide primitives for uniquely localizing WSN nodes. The goal is to maximize the number of uniquely localized nodes assuming a fully decentralized model of computation. Each node constructs a cluster of its own and ... -
GSPIM: Graphical visualization tool for MIPS assembly programming and simulation
Borunda, Patrick; Brewer, Chris; Erten, Cesim (2007)We describe our system, GSPIM, used for visualization of low-level MIPS Assembly programming and simulation. Although many visualization tools for algorithms and high-level programs have been considered in educational ... -
A robust biclustering method based on crossing minimization in bipartite graphs
Erten, Cesim; Sözdinler, Melih (Springer-Verlag Berlin, 2009)[No abstract available] -
A robust localization framework to handle noisy measurements in wireless sensor networks
Erten, Cesim; Karataş, Ömer (IEEE, 2009-09-14)We construct a robust localization framework to handle noisy measurements in wireless sensor networks. Traditionally many approaches employ the distance information gathered from ranging devices of the sensor nodes to ...
