Hybrid job scheduling for improved cluster utilization
(Springer Science+Business Media, 2014)In this paper, we investigate the models and issues as well as performance benefits of hybrid job scheduling over shared physical clusters. Clustering technologies that are currently supported include MPI, Hadoop-MapReduce ... -
Evaluation of linguistic and prosodic features for detection of Alzheimer’s disease in Turkish conversational speech
(Springer Science+Business Media, 2015-12)Automatic diagnosis and monitoring of Alzheimer’s disease can have a significant impact on society as well as the well-being of patients. The part of the brain cortex that processes language abilities is one of the earliest ... -
Eigenvoice speaker adaptation with minimal data for statistical speech synthesis systems using a MAP approach and nearest-neighbors
(IEEE, 2014-12)Statistical speech synthesis (SSS) systems have the ability to adapt to a target speaker with a couple of minutes of adaptation data. Developing adaptation algorithms to further reduce the number of adaptation utterances ... -
A small footprint hybrid statistical and unit selection text-to-speech synthesis system for Turkish
(Springer Science+Business Media, 2012)Unit selection based text-to-speech synthesis (TTS) can generate high quality speech. However, The HMM-based text-to-speech (HTS) has also advantages such as the lack of spurious errors that are observed in the unit selection ... -
Parental scaffolding as a bootstrapping mechanism for learning grasp affordances and imitation skills
(Cambridge University Press, 2015-06)Parental scaffolding is an important mechanism that speeds up infant sensorimotor development. Infants pay stronger attention to the features of the objects highlighted by parents, and their manipulation skills develop ... -
Performance evaluation of unfolded sparse matrix-vector multiplication
(2015-01)Sparse matrix-vector multiplication (spMV) is a kernel operation in scientific com- putation. There exist problems where a matrix is repeatedly multiplied by many different vectors. For such problems, specializing the spMV ... -
Minimal sign representation of boolean functions: algorithms and exact results for low dimensions
(MIT Press, 2015-08)Boolean functions (BFs) are central in many fields of engineering and mathematics, such as cryptography, circuit design, and combinatorics. Moreover, they provide a simple framework for studying neural computation mechanisms ... -
Staged development of robot skills: behavior formation, affordance learning and imitation
(IEEE, 2015-06)Inspired by infant development, we propose a three staged developmental framework for an anthropomorphic robot manipulator. In the first stage, the robot is initialized with a basic reach-and- enclose-on-contact movement ... -
Inference management, trust and obfuscation principles for quality of information in emerging pervasive environments
(Elsevier, 2014-04)The emergence of large scale, distributed, sensor-enabled, machine-to-machine pervasive applications necessitates engaging with providers of information on demand to collect the information, of varying quality levels, to ... -
Constrained min-cut replication for k-way hypergraph partitioning
(Informs, 2014)Replication is a widely-used technique in information retrieval and database systems for providing fault tolerance and reducing parallelization and processing costs. Combinatorial models based on hypergraph partitioning ... -
Improving models for model-based testing based on exploratory testing
(2014-08)Model bazlı test, test edilen sistemin modelleri sayesinde otomatik olarak test senaryoları oluşturulmasını sağlar. Bu modellerin doğruluğu ve tamlığı oluşturulan test senaryolarının etkinliğini belirler. Genelde manuel ... -
High-performance low-complexity near-lossless embedded memory compression for HDTV
(2014-08)HDTV video işlemcileri çerçeve hızı değiştirme, binişme giderme ve diğer video iyileştirme işlemlerini yapabilmek için, bir ya da daha fazla geçmiş çerçeveyi hafızada tutmak durumundadır. HD çözünürlüklerde sıkıştırılmamış ... -
Fault masking as a service
(Wiley, 2014-07)In SOA, composite services depend on a set of partner services to perform their tasks. These partner services may become unavailable because of system and/or network faults, leading to an increased error rate for the ... -
Hybrid job scheduling for improved shared cluster utilization
(2014-01)Bu tezde, bilgisayar küme yapıları üzerinde hibrid iş yüklerinin birlikte işlenmesiyle ilgili modeller, sorunlar ve performans kazanımları incelenmektedir. Desteklenen kümeleme teknolojileri arasında MPI, Hadoop-MapReduce ... -
Analysis of speaker similarity in the statistical speech synthesis systems using a hybrid approach
(IEEE, 2012)Statistical speech synthesis (SSS) approach has become one of the most popular and successful methods in the speech synthesis field. Smooth speech transitions, without the spurious errors that are observed in unit selection ... -
A small footprint hybrid statistical/unit selection text-to-speech synthesis system for agglutinative languages
(IEEE, 2012)Despite its success, unit selection based text-to-speech synthesis (TTS) has has some disadvantages such as sudden discontinuities in speech that distract the listeners. The HMM-based TTS (HTS) approach has been increasingly ... -
Maximum likelihood estimate of parameters of Nakagami-m distribution
(IEEE, 2012)Nakagami-m distribution is well known for its ability to model a number of probability density functions, be it symmetric or asymmetric. Many Maximum Likelihood parameter estimation techniques for this distribution have ... -
Reasoning with uncertain information and trust
(SPIE, 2013)A limitation of standard Description Logics is its inability to reason with uncertain and vague knowledge. Although probabilistic and fuzzy extensions of DLs exist, which provide an explicit representation of uncertainty, ... -
Nearest neighbor approach in speaker adaptation for HMM-based speech synthesis
(IEEE, 2013)Statistical speech synthesis (SSS) approach has become one of the most popular and successful methods in the speech synthesis field. Smooth speech transitions, without the spurious errors that are observed in unit selection ... -
Online association rule mining over fast data
(IEEE, 2013)To extract useful and actionable information in real-time, the information technology (IT) world is coping with big data problems today. In this paper, we present implementation details and performance results of ReCEPtor, ...
