A hybrid reasoning mechanism for effective sensor selection for tasks
de Mel, G.; Şensoy, Murat; Vasconcelos, W.; Norman, T. J. (Elsevier, 2013-02)In this paper, we present Ontological Logic Programming (OLP), a novel approach that combines logic programming with ontological reasoning. OLP enables the use of ontological terms (i.e., individuals, classes and properties) ... -
Identifying critical architectural components with spectral analysis of fault trees
Ayav, T.; Sözer, Hasan (Elsevier, 2016-12)We increasingly rely on software-intensive embedded systems. Increasing size and complexity of these hardware/software systems makes it necessary to evaluate reliability at the system architecture level. One aspect of this ... -
Impact of education and experience level on the effectiveness of exploratory testing: an industrial case study
Şahin Gebizli, Ceren; Sözer, Hasan (IEEE, 2017)Exploratory Testing (ET) is a widely applied approach in practice. This approach relies on the knowledge and experience of test engineers and technicians who perform ET. Hence, we aimed at evaluating the impact of education ... -
Implementation of SAND architecture Using SDN
Kalan, R. S.; Sayit, M.; Beğen, Ali Cengiz (IEEE, 2018)The server and network-assisted DASH (SAND) concept aims to increase the performance of Dynamic Adaptive Streaming over HTTP (DASH) systems. As being one of the future Internet technologies, SDN provides advantages to ... -
Improving automatic emotion recognition from speech signals
Bozkurt, E.; Erzin, E.; Eroğlu Erdem, Ç.; Erdem, Tanju (International Speech Communications Association, 2009)We present a speech signal driven emotion recognition system. Our system is trained and tested with the INTERSPEECH 2009 Emotion Challenge corpus, which includes spontaneous and emotionally rich recordings. The challenge ... -
Improving models for model-based testing based on exploratory testing
Gebizli, C. Ş.; Sözer, Hasan (IEEE, 2014)Model-based testing facilitates automatic generation of test cases by means of models of the system under test. Correctness and completeness of these models determine the effectiveness of the generated test cases. Critical ... -
Improving models for model-based testing based on exploratory testing
Gebizli, Ceren Şahin (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 ... -
An in-depth look at prior art in fast round-robin arbiter circuits
Uğurdağ, Hasan Fatih; Baskirt, O. (Özyeğin University, 08.01.2011)Arbiters are found where shared resources exist such as busses, switching fabrics, processing elements. Round-robin is a fair arbitration method, where requestors get near-equal shares of a common resource or service. ... -
Increasing test efficiency by risk-driven model-based testing
Gebizli, C. Ş.; Kırkıcı, A.; Sözer, Hasan (Elsevier, 2018-10)We introduce an approach and a tool, RIMA, for adapting test models used for model-based testing to augment information regarding failure risk. We represent test models in the form of Markov chains. These models comprise ... -
Inference management, trust and obfuscation principles for quality of information in emerging pervasive environments
Bisdikian, C.; Gibson, C.; Chakraborty, S.; Srivastava, M. B.; Şensoy, Murat; Norman, T. J. (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 ... -
Inferring human values for safe AGI design
Sezener, Can Eren (Springer International Publishing, 2015)Aligning goals of superintelligent machines with human values is one of the ways to pursue safety in AGI systems. To achieve this, it is first necessary to learn what human values are. However, human values are incredibly ... -
Integrated static code analysis and runtime verification
Sözer, Hasan (Wiley, 2015-10)Static code analysis tools automatically generate alerts for potential software faults that can lead to failures. However, these tools usually generate a very large number of alerts, some of which are subject to false ... -
Interest-based negotiation for policy-regulated asset sharing
Parizas, C.; de Mel, G.; Preece, A. D.; Şensoy, Murat; Calo, S. B.; Pham, T. (Springer Nature, 2016)Resources sharing is an important but complex problem to be solved. The problem is exacerbated in a coalition context due to policy constraints, that reflect concerns regarding security, privacy and performance to name a ... -
Interpretability of deep learning models: a survey of results
Chakraborty, S.; Tomsett, R.; Raghavendra, R.; Harborne, D.; Alzantot, M.; Cerutti, F.; Srivastava, M.; Preece, A.; Julier, S.; Rao, R. M.; Kelley, T. D.; Braines, D.; Şensoy, Murat; Willis, C. J.; Gurram, P. (IEEE, 2018-06-26)Deep neural networks have achieved near-human accuracy levels in various types of classification and prediction tasks including images, text, speech, and video data.
