Towards extending the W, Z/ν, δ paradigm for first passage problems ofL´evy processes to strong Markov processes without positive jumps



Towards finding optimal mixture of subspaces for data classification
Musa, Mohamed Elhafiz Mustafa; Atalay, Mehmet Volkan; Department of Computer Engineering (2003)
In pattern recognition, when data has different structures in different parts of the input space, fitting one global model can be slow and inaccurate. Learning methods can quickly learn the structure of the data in local regions, consequently, offering faster and more accurate model fitting. Breaking training data set into smaller subsets may lead to curse of dimensionality problem, as a training sample subset may not be enough for estimating the required set of parameters for the submodels. Increasing the ...
Towards designing audio assistance for comprehending haptic graphs A multimodal perspective
DENİZ, OZAN; MEHMETCAN, FAL; Acartürk, Cengiz (2013-07-31)
Statistical graphs, such as line graphs are widely used in multimodal communication settings. Language accompanies graphs and humans produce gestures during the course of communication. For visually impaired people, haptic-audio interfaces provide perceptual access to graphical representations. The local and sequential character of haptic perception introduces limitations in haptic perception of hard-to-encode information, which can be resolved by providing audio assistance. In this article we first present...
Towards a systematic understanding of graphical cues in communication through statistical graphs
Acartürk, Cengiz (2014-04-01)
Statistical graphs in particular, line graphs and bar graphs are efficient means of communication in a wide range of non-expert settings. In communication settings, statistical graphs do not only serve as visualizations of individual data points but also provide visual access to various aspects of the information contained in data. Moreover, specific types of graphs are better means for providing visual access to certain aspects of data. For instance, trend information is visually conveyed through line grap...
Towards Group Cognitive Analysis of Collaborative Learning with Eye Tracking and Brain Imaging Technologies
Çakır, Murat Perit (null; 2013-06-15)
This paper aims to motivate the need for a group cognitive approach for the multimodal analysis of learning to better account for neural and ocular correlates of collaborative learning. In reference to related work in the emerging fields of two-person neuroscience and dual-eye tracking, the paper argues for the need for moving from a singlemind perspective to a group cognitive perspective where neural and ocular correlates of joint meaning making are investigated in the context of sequentially unfolding soc...
Towards Usable Solutions to Graphical Password Hotspot Problem
BIÇAKCI, KEMAL; ATALAY, NART BEDİN; Yuceel, Mustafa; Gurbaslar, Hakan; Erdeniz, Burak (2009-07-24)
Click based graphical passwords that use background images suffer from hot-spot problem. Previous graphical password schemes based on recognition of images do not have a sufficiently large password space suited for most Internet applications. In this paper, we propose two novel graphical password methods based on recognition of icons to solve the hotspot problem without decreasing the password space. The experiment we have conducted that compares the security and usability of proposed methods with earlier w...
