In the ever-expanding landscape of enterprise data management, the Multi-Dimensional Data Model (MDM) emerges as a transformative tool, offering a comprehensive approach to sorting, analyzing, and ...

Every stage of a network’s lifecycle, from planning, rollout, to maintenance and restoration, needs to be built on solid data from multiple dimensions. This includes data not only from the services ...

In the field of smart logistics, Jiaozuo Dawn Steps Technology Co., Ltd. has recently applied for a patent titled "A Smart Logistics Solution System Based on Big Data and Blockchain." This innovative ...

This paper shows that the Expectation-Maximization (EM) algorithm for regime-switching dynamic factor models provides satisfactory performance relative to other estimation methods and delivers a good ...

High-dimensional loading parameters are allowed in our development, under reasonable theoretical conditions. Thus, we propose a regularized estimation procedure to select the significant nonzero ...

Real-world compositional data sets are often complex owing to high-dimensionality, heavy tails, and the possible existence of outliers. We consider a general class of elliptical distributions to model ...
