Design and Implementation of Solution Algorithm for Foreign Key Conflict Based on Directed Graph [PDF]
Jisuanji gongcheng, 2021 As one of the important constraints in relational databases,foreign keys play an important role in constraining the order of operations of the database.However,in some cases,users cannot know the order of operations,causing foreign key conflicts.To solve

Directed Acyclic Graphs With Tears
IEEE Transactions on Artificial Intelligence, 2023 Bayesian network is a frequently-used method for fault detection and diagnosis in industrial processes. The basis of Bayesian network is structure learning which learns a directed acyclic graph (DAG) from data. However, the search space will scale super-exponentially with the increase of process variables, which makes the data-driven structure learning

Acyclic Partitioning of Large Directed Acyclic Graphs [PDF]
2017 17th IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing (CCGRID), 2017 Finding a good partition of a computational directed acyclic graph associated with an algorithm can help find an execution pattern improving data locality, conduct an analysis of data movement, and expose parallel steps. The partition is required to be acyclic, i.e., the inter-part edges between the vertices from different parts should preserve an ...

Tutorial on directed acyclic graphs
Journal of Clinical Epidemiology, 2022 Directed acyclic graphs (DAGs) are an intuitive yet rigorous tool to communicate about causal questions in clinical and epidemiologic research and inform study design and statistical analysis. DAGs are constructed to depict prior knowledge about biological and behavioral systems related to specific causal research questions.

IoT-enabled directed acyclic graph in spark cluster
Journal of Cloud Computing: Advances, Systems and Applications, 2020 Real-time data streaming fetches live sensory segments of the dataset in the heterogeneous distributed computing environment. This process assembles data chunks at a rapid encapsulation rate through a streaming technique that bundles sensor segments into
