Closeness and uncertainty aware adversarial examples detection in adversarial machine learning
Tuna, Ömer Faruk; Çatak, Ferhat Özgür; Eskil, Mustafa Taner (Elsevier Ltd, 2022-07)While deep learning models are thought to be resistant to random perturbations, it has been demonstrated that these architectures are vulnerable to deliberately crafted perturbations, albeit being quasi-imperceptible. These ... -
Convolutional neural network (CNN) algorithm based facial emotion recognition (FER) system for FER-2013 dataset
Ezerceli, Özay; Eskil, Mustafa Taner; 0000-0002-7877-7528 (IEEE, 2022-11-18)Facial expression recognition (FER) is the key to understanding human emotions and feelings. It is an active area of research since human thoughts can be collected, processed, and used in customer satisfaction, politics, ... -
Detecting facial features automatically
Olzvoi, Uranchimeg (Işık Üniversitesi, 2013-07-02)There are many algorithms and approaches in object detection world. Many of them are based on Viola Jones algorithm. According to our observations, the features which help to detect an object are very critical for the ... -

The goal of this study is to investigate the performance of different classifier fusion techniques in a driver recognition scenario. We are using solely driving ... -
El yazısı rakam sınıflandırması için gözetimsiz benzerlik tabanlı evrişimler
Erkoç, Tuğba; Eskil, Mustafa Taner (Institute of Electrical and Electronics Engineers Inc., 2022)Effective training of filters in Convolutional Neural Networks (CNN) ensures their success. In order to achieve good classification results in CNNs, filters must be carefully initialized, trained and fine-tuned. We propose ... -
Evrisimsel sinir ağları ile rekabetçi derin öğrenme
Eskil, Mustafa Taner (Tübitak, 2021-09-15)İmge üzerinde nesne tanımada, nesnenin imge üzerindeki yeri, açısal yönelimi ve ölçeği algoritmik olarak çözülmesi gereken önemli zorluklardır. Bu zorlukları aşmak için son yıllarda en sık kullanılan ve en başarılı sonuçları ... -
Exploiting epistemic uncertainty of the deep learning models to generate adversarial samples
Tuna, Ömer Faruk; Çatak, Ferhat Özgür; Eskil, Mustafa Taner (Springer, 2022-03)Deep neural network (DNN) architectures are considered to be robust to random perturbations. Nevertheless, it was shown that they could be severely vulnerable to slight but carefully crafted perturbations of the input, ... -
Extraction and selection of muscle based features for facial expression recognition
Benli, Kristin Surpuhi; Eskil, Mustafa Taner (IEEE Computer Soc, 2014-12-04)In this study we propose a new set of muscle activity based features for facial expression recognition. We extract muscular activities by observing the displacements of facial feature points in an expression video. The ... -
Fabric defect detection in frequency domain using fourier analysis
Titrek, Nuri Gökay (Işık Üniversitesi, 2016)An overwhelming majority of image processing based defect detection approaches rely on machine learning methods to train a model for comparison of test examples. This requires a training phase for each item to be learned ... -
Facial expression recognition based on anatomy
Eskil, Mustafa Taner; Benli, Kristin Surpuhi (Academic Press Inc Elsevier Science, 2014-02)In this study, we propose a novel approach to facial expression recognition that capitalizes on the anatomical structure of the human face. We model human face with a high-polygon wireframe model that embeds all major ... -
