My Events and Announcements
- I will give a talk at Northwestern Polytechnical University in Xi'An on the 14th of May on emotion recognition from videos. This is a one-day event, organized by Prof. Dongmei Jiang. On the 15th of May, the Human Behavior Understanding workshop will be held (at IEEE FG), where I will present our work on continuous driver authentication. Between 20-22 May, I will be in Beijing for ACII Asia, and will present there our new multimodal bipolar patient corpus. This corpus will be used in the AVEC 2018 Challenge.
- We are organizing the 9th HBU Workshop at ECCV 2018 on "Generating Realistic Visual Data of Human Behavior," together with Xavier Alameda-Pineda, Elisa Ricci, Nicu Sebe, and Shuicheng Yan. Keynotes are Michael Black and Stefanos Zafeirou. The submission deadline is 15 June. A special issue of IJCV will follow the workshop with the same topic. Submission deadline for the journal special issue is 30 September.
- We are organizing the Data for Refugees (D4R) Challenge with Türk Telekom and TÜBİTAK. This challenge makes mobile CDR data of 1 million people, collected over one year, and carefully anonymized, available to researchers. We invite researchers to use it to propose solutions to refugee issues on health, education, security, unemployment, and integration. The winners of each category will receive prizes. The results will be summarized in a white paper, and shared with related ministries and NGOs.
- Our Data for Refugees project with Prof. Alex Pentland (MIT, Media Lab) has received funding from MISTI MIT-Bogazici University Seed Fund.
- We are organizing the 5th Int. Symposium on Brain and Cognitive Science at Bogazici University, on 6 May 2018. The keynotes are Prof. Patrick Haggard (University College London) and Prof. Ash Asudeh (University of Oxford). Prof. Ethem Alpaydın is chairing a panel entitled "How Deep is Your Learning". The participation will be free for all attendees..
- We are organizing the 8th Int. Workshop on Human Behavior Understanding at IEEE FG 2017, in Xi'An. The keynotes are Stephen Brewster and Hongying Meng. The program is now available.
- I will be on sabbatical at Nagoya University until August 2018.
- (in Turkish) Yapay zeka üzerine Etiya ile yaptığımız sohbetleri Youtube'da bulabilirsiniz (1. kısım; 2. kısım; 3. kısım; 4. kısım).
- We won the ChaLearn LAP Job Candidate Screening Coopetition at CVPR'17. Details of the system can be found in the paper: "Multi-modal Score Fusion and Decision Trees for Explainable Automatic Job Candidate Screening from Video CVs".
- I have joined the Editorial Board of The International Journal of Human-Computer Studies, which publishes interdisciplinary work on interactive systems, covering research in computing, artificial intelligence, psychology, linguistics, communication, design, engineering, and social organization.
- I have joined the Editorial Board of IEEE Trans. of Affective Computing, which focuses on the design of systems that can recognize, interpret, and simulate human emotions and related affective phenomena.

- The Turkish computer vision and pattern recognition community started an e-mail communication list, and the number of its members reached a hundred just one day after it was set up. The communication language is mainly Turkish. Look for "firstname.lastname@example.org". Please join in and spread the word.
- The Boğaziçi-DeviantArt Image Reuse Database (BODAIR) went public. The paper that describes it was presented at the 3rd Workshop on Computer Vision for Art Analysis (VISART@ECCV) in Amsterdam, Oct. 16.
- You can download the slides for the Workshop on Teaching Style and Content for the training of teaching assistants. These are partly based (with much compression and simplification) on the material from the BKO certification program (webpage in Dutch), offered by the University of Amsterdam.
- In January 2016, the IEEE Transactions on Autonomous Mental Development (TAMD) was renamed and became the IEEE Transactions on Cognitive and Developmental Systems (TCDS). TCDS will focus on advances in the study of development and cognition in natural (humans, animals) and artificial (robots, agents) systems.
- If you are interested in hearing about cognitive science related events in Turkey, please subscribe to our mailing list (moderated) email@example.com.
- A new journal, EAI Endorsed Transactions on Creative Technologies is initiated to create synergies between computational arts, applied sciences and creative industries. The journal solicits long and short papers now, and it is both open access and free for the authors.
- The Cognitive Science program of Bogazici University signed an Erasmus agreement with Tilburg Center for Cognition and Communication (TiCC), as well as with University of Trento.
- The UvA-NEMO Smile database went public! See the website for details on how to obtain it, and check here the coverage in the media. Learn more about our experiment on
the effect of dynamic information for facial age and expression estimation here (in Dutch) and here (in English). The public report (in Dutch) can be downloaded here.

Face recognition has been an active area of study for both computer
vision and image processing communities, not only for biometrics but
also for human-computer interaction applications. The purpose of the
present work is to evaluate the existing 3D face recognition techniques
and seek biologically motivated methods to improve them. We especially
look at findings in psychophysics and cognitive science for insights.
We propose a biologically motivated computational model, and focus on
the earlier stages of the model, whose performance is critical for the
later stages. Our emphasis is on automatic localization of facial
features. We first propose a strong unsupervised learning algorithm for
flexible and automatic training of Gaussian mixture models and use it
in a novel feature-based algorithm for facial fiducial point
localization. We also propose a novel structural correction algorithm
to evaluate the quality of landmarking and to localize fiducial points
under adverse conditions. We test the effects of automatic landmarking
under rigid and non-rigid registration methods. For the rigid
registration approach, we implement the iterative closest point method
(ICP). The most important drawback of ICP is the computational cost of
registering a test scan to each scan in the gallery. By using an
average face model in rigid registration, we show that the computation
bottleneck can be eliminated. Following psychophysical arguments on the
"other race effect", we reason that organizing faces into different
gender and morphological groups will help us in designing more
discriminative classifiers. We test this claim by employing different
average face models for dense registration. We propose a shape-based
clustering approach that assigns faces into groups with nondescript
gender and race. Finally, we propose a regular re-sampling step that
increases the speed and the accuracy significantly. These components
make up a full 3D face recognition system.

- The IMoFA algorithm (incremental mixtures of factor analyzers) in MATLAB (download). This
algorithm performs automatic clustering and model selection in an unsupervised manner. The model is basically a
Gaussian mixture, but from a complexity point of view, the output will be between a diagonal-covariance GMM and a
full-covariance GMM, thanks to the latent variable assumptions. The demonstration code models the Iris data with IMoFA,
and shows how classification can be effected with the trained models.
- The GOLLUM algorithm (Gaussian outlier localization with likelihood margins) in MATLAB (download). GOLLUM is a morphological algorithm that learns landmark distributions for the purpose
of detecting and correcting a given landmark constellation, irrespective of the underlying feature distribution. It can
be used for detecting landmark localization errors automatically, providing expected locations for landmarks, and for
correcting a given landmark location based on other landmarks. The provided code uses the Levenberg-Marquard algorithm
from the Optimization Toolbox of MATLAB, but this step can be replaced with a custom algorithm. The demonstration code
shows how to operate GOLLUM to correct randomly corrupted facial landmark data.
