Data modeling is the process of designing and organizing data structures to support a specific purpose or application. One of the earliest and most widely used data models is the hierarchical ...

The adjacency list model is a way of storing hierarchical data in a relational table by adding a column that references the primary key of the parent row. For example, if you have a table of ...

In machine learning, a hierarchical model is an approach that organises data and learning processes into layered structures. This structure reflects the inherent hierarchical nature of many real ...

However, if the amount of data from each group is small ... can be reduced by leveraging the potential similarities among the groups. This is what hierarchical modeling does - it provides ...

In the suggested hierarchical model, an expression QTL (eQTL) model (which is essentially our missing data model) is part of the larger cQTL model and it represents a Bayesian model-based method ...

The Purdue Model has provided a hierarchical structure for industrial communications to keep computing and networks deterministic. But in the age of IoT, data flow is no longer hierarchical. So what ...

Henchion, M., Bacher, I. and Mac Namee, B., 2021. A Sentence-level Hierarchical BERT Model for Document Classification with Limited Labelled Data. arXiv preprint arXiv:2106.06738. (to be pulished in ...

This paper contributes to the development of a new statistical modeling and computation method for analyzing heterogeneous degradation data. We adopt the random-coefficient degradation path approach, ...

As no prior studies have analyzed the CDM fit for polytomous response data with attribute hierarchy, the current study concentrates on a novel model, named as the sequential hierarchical CDM (SH-CDM), ...

Loss data structures in non-life insurance businesses are increasingly complex, and the tendency of correlation and heterogeneity is gradually presented. Hierarchical model can breakthrough limitation ...
