To evaluate the performance of speaker recognition systems, a detection cost function defined as a weighted sum of the probabilities of type I and type II errors is employed. The speaker datasets may have data dependency due to multiple uses of the same subjects. Using the standard errors of the detection cost function computed by means of the two-layer nonparametric two-sample bootstrap method...

Relation classification is associated with many potential applications in the artificial intelligence area. Recent approaches usually leverage neural networks based on structure features such as syntactic or dependency features to solve this problem. However, high-cost structure features make such approaches inconvenient to be directly used. In addition, structure features are probably domainde...

The National Institute of Standards and Technology (NIST) conducts an ongoing series of Speaker Recognition Evaluations (SRE). Speaker detection performance is measured using a detection cost function defined as a weighted sum of the probabilities of type I error and of type II error. The sampling variability can result in measurement uncertainties. Thus, the uncertainties of the detection cost...

background: although extensive development of technology provides welfare and accessibility for families but it may be one of the threatening factors for them. the unique characteristics of internet such as availability and facility are useful, but over using for its exciting content cause to internet addiction between family members. the aim of this study was to explain the experiences of the ...

Dependency analysis of critical infrastructures is a computationally intensive problem when dealing with large-scale, cross-sectoral, cascading and common-cause failures. The problem intensifies when attempting a dynamic, time-based dependency analysis. This paper extends a previous graph-based risk analysis methodology to dynamically assess the evolution of cascading failures over time. Variou...

this research deals with the concept of uniqueness in creativity as one of the artist's concerns and her personal features differentiates her from her peers in literary approach and critical view horizon based on her learned knowledge and literature.the reflection of such concept can be found in the book teyf-e- al-khialwritten by sharif al-murtazain both poetry and its criticism. the poet...
