Translating Workflow Nets to Process Trees: An Algorithmic Approach [article]

Sebastiaan J. van Zelst
2020 arXiv   pre-print
Yet, an algorithm that translates a WF-net into a process tree is of great interest, e.g., the explicit knowledge of the control-flow hierarchy in a WF-net allows one to more easily reason on its behavior  ...  A process tree is easily translated into a sound Workflow net (WF-net), however, the reverse is not the case.  ...  Translating Workflow Nets to Process Trees In this section, we describe our main approach. In Section 3.1, we sketch the main idea of the approach.  ...

A Combination of the evolutionary tree miner and simulated annealing

Afina Lina Nurlaili, Riyanarto Sarno
2017 2017 4th International Conference on Electrical Engineering, Computer Science and Informatics (EECSI)  
In recent years, process mining is important to discover process model from event logs; however the existing methods have not achieved good in overall fitness.  ...  The results of the proposed method which was compared to other approaches show that the proposes method had better in overall fitness and better quality of individuals.  ...  Firstly, an event log was taken as input in the algorithm. Then a workflow net was produced from mining an event log. The algorithm was modelled by Petri net.  ...

An Incremental Approach to the Analysis and Transformation of Workflows Using Region Trees

R.F. Hauser, M. Friess, J.M. Kuster, J. Vanhatalo
2008 IEEE Transactions on Systems Man and Cybernetics Part C (Applications and Reviews)  
An RT is similar to a program structure tree and imposes a hierarchy of regions as an overlay structure onto the workflow model.  ...  It allows an incremental approach to the analysis and transformation of workflows, and thereby, significantly reduces the overhead because individual regions can be dealt with separately.  ...  To enable workflow analysis and workflow transformation for an incremental and iterative approach, we introduce the concept of a region tree (RT).  ...

Ant Colony Decision Tree Method to Detect the Suspicious News

2019 International journal of recent technology and engineering  
In this research work, an ensemble approach is considered to detect suspicious news content. Here, Ant Colony Decision Tree method is ensembled for the detection of suspicious news (ACDTDSN).  ...  Despite the presence of existing methods for the suspicious news detection exists, but the continuous growth of such activities is difficult to manage with an individual approach.  ...  The decision trees are constructed using the CART algorithm to lower down the possible mean squared errors.  ...

Deep Semantic Instance Segmentation of Tree-like Structures Using Synthetic Data [article]

Kerry Halupka, Rahil Garnavi, Stephen Moore
2018 arXiv   pre-print
Tree-like structures, such as blood vessels, often express complexity at very fine scales, requiring high-resolution grids to adequately describe their shape.  ...  Key to our approach is the use of a novel multi-task loss function, enabling instance segmentation of arbitrarily complex branching structures.  ...  The latter allows the network to cluster an arbitrary number of branches, which can be identified in a post-processing step.  ...
