Missing values can occur frequently in many real world situations. Such is the case of multi-way data applications, where objects are usually represented by arrays of 2 or more dimensions e.g. biomedical signals that can be represented as time-frequency matrices. This lack of attributes tends to influence the analysis of the data. In classification tasks for example, the performance of classifi...

this study aimed to evaluate persian search engines based on the criteria obtained from alexa databank using correspondence analysis. through searching the web, 23 search engines were found, which due to their cease and no coverage by alexa, this number was reduced to 16. data analysis revealed that ghatreh search engine occupied a high rank in most of attributes like traffic rank, time spent o...

Rock typing is known as the best way in heterogeneous reservoirs characterization. The rock typing methods confine to various aspects of the rocks such as multi-scale and multi-modal pore types and size, rock texture, diagenetic modifications and integration of static/dynamic data. Integration of static and dynamic behavior of rocks and their sedimentary features are practiced in this study. Po...

the machine made carpet industry is one of the main and most famous industries in iran and especially in the city of yazd. however there is little information about customer preferences for different attributes of this product. in this article we tried to estimate the relative importance of the main attributes affecting customer desire for purchasing machine made carpet and the utility values f...

We investigated the binding problem (e.g. the combination of edge information across attributes), using an orientation aftereffect paradigm (OAE). Horizontal layers of vertical edges were phase-shifted to create a global near-vertical orientation. Multi-attribute displays were created by alternating the attribute defining edges (e.g. luminance, colour, texture or motion) across layers. OAE magn...

Multi-attributed graph matching is a problem of finding correspondences between two sets of data while considering their complex properties described in multiple attributes. However, the information of multiple attributes is likely to be oversimplified during a process that makes an integrated attribute, and this degrades the matching accuracy. For that reason, a multi-layer graph structure-bas...

divine names and attributes have a great bearing on the relationship between man and god in respects such as belief in and supplication to him. the semantic dimension of this issue has been the focus of attention in the philosophy of religion. this aspect of divine names and attributes is concerned with questions as to how to discuss god’s names and how these names relate to man’s attributes. i...

The fundamental question studied in this thesis is how to evaluate and analyse supervised learning algorithms and classifiers. As a first step, we analyse current evaluation methods. Each method is described and categorised according to a number of properties. One conclusion of the analysis is that performance is often only measured in terms of accuracy, e.g., through cross-validation tests. Ho...
