Establishing Continuous App Improvement by Considering Heterogenous Data Sources

A Query Interface for Heterogenous Biological Data Sources

Keyword search across distributed heterogenous structured data sources

Many applications and users require integrated data from multiple, distributed, heterogeneous (semi-) structured sources. Sources are relational databases, XML databases, or even structured Web resources. Mediator systems represent one class of solutions for data integration. They provide a uniform view and uniform way to query the virtually integrated data. As data resides in the local sources...

Continuation Methods for Mixing Heterogenous Sources

A number of modern learning tasks involve esti­ mation from heterogeneous information sources. This includes classification with labeled and un­ labeled data as well as other problems with anal­ ogous structure such as competitive (game theo­ retic) problems. The associated estimation prob­ lems can be typically reduced to solving a set of fixed point equations (consistency conditions). We intr...

modeling loss data by phase-type distribution

بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...

Considering Fading Effects for Vertical Handover in Heterogenous Wireless Networks

Considering Fading Effects for Vertical Handover in Heterogenous Wireless Networks Over the years, vertical handover has attracted the interest of numerous researchers. Despite the attractive benefits of integrating different wireless platforms, mobile users are confronted with the issue of detrimental handover. As a mobile node (MN) moves within a heterogeneous environment, satisfactory qualit...
