Effects of Graph Type in the Comprehension of Cyclic Events

This study presents an analysis of the effect of different graph types on the comprehension of cyclic events. The results indicated that although round and linear graph designs are informationally equivalent, the round graphs are computationally better suited than linear graphs for the interpretation of cyclic concepts.


Effect of Using Regression in Sentiment Analysis
Onal, Itir; Ertuğrul, Ali Mert (2014-04-25)
In this study, the effect of using regression on sentiment classification of Twitter data was analyzed. In other words, whether the strength of sentiment better discriminates the classes or not. Since our dataset includes class confidence scores rather than discrete class labels, regression analysis was employed on each class separately. Then, each tweet was assigned the class whose estimated confidence score is maximum among others after regression. The feature set used includes unigrams, POS tags, emotico...
Functions of autobiographical memory during mother-adolescent reminiscing and their relation to emotion regulation strategies
Elibol Pekaslan, Nur; Şahin Acar, Başak; Department of Psychology (2019)
The aim of the current study was to examine the functions of autobiographical memory (AM) during mother-adolescent reminiscing, and to investigate dyadic relationships between the functions and emotion regulation (ER) strategies with a mixed method. For the qualitative part, content analysis revealed that Self, Social, and Directive functions occurred as the main themes, and each function also included ER themes. For the quantitative part, the first aim was to examine the differences in the frequencies rega...
A systematic study of probabilistic aggregation strategies in swarm robotic systems
Soysal, Onur; Şahin, Erol; Department of Computer Engineering (2005)
In this study, a systematic analysis of probabilistic aggregation strategies in swarm robotic systems is presented. A generic aggregation behavior is proposed as a combination of four basic behaviors: obstacle avoidance, approach, repel, and wait. The latter three basic behaviors are combined using a three-state finite state machine with two probabilistic transitions among them. Two different metrics were used to compare performance of strategies. Through systematic experiments, how the aggregation performa...
Effects of culture on computer-supported international collaborations
Swigger, K; Alpaslan, Ferda Nur; Brazile, R; Monticino, M (Elsevier BV, 2004-03-01)
This paper discusses results of a case study from an on-going project to investigate how cultural factors, as identified by the Cultural Perspectives Questionnaire (CPQ), affect the performance of distributed collaborative learning teams. The results indicate that a team's cultural composition is a significant predictor of its performance on programming projects. Cultural attributes most strongly correlated to group performance included those related to attitudes about organizational hierarchy, organization...
Effect of human prior knowledge on game success and comparison with reinforcement learning
Hasanoğlu, Mert.; Çakır, Murat Perit; Department of Cognitive Sciences (2019)
This study aims to find out the effect of prior knowledge on the success of humans in a non-rewarding game environment, and then to compare human performance with a reinforcement learning method in an effort to observe to what extent this method can be brought closer to human behavior and performance with the data obtained. For this purpose, different versions of a simple 2D game were used, and data were collected from 32 participants. At the end of the experiment, it is concluded that prior knowledge, such...
