Modeling Unknown Stochastic Dynamical System via Autoencoder

no code implementations15 Dec 2023 Zhongshu Xu, Yuan Chen, Qifan Chen, Dongbin Xiu

We present a numerical method to learn an accurate predictive model for an unknown stochastic dynamical system from its trajectory data.

A Deep Learning Approach for Repairing Missing Activity Labels in Event Logs for Process Mining

no code implementations17 Feb 2022 Yang Lu, Qifan Chen, Simon K. Poon

The performance of existing process discovery algorithms can be affected when there are missing activity labels in event logs.

A Novel Approach to Discover Switch Behaviours in Process Mining

1 code implementation24 Jun 2021 Yang Lu, Qifan Chen, Simon Poon

Process mining is a relatively new subject which builds a bridge between process modelling and data mining.

A Multi-View Framework to Detect Redundant Activity Labels for More Representative Event Logs in Process Mining

no code implementations30 Mar 2021 Qifan Chen, Yang Lu, Charmaine S. Tam, Simon K. Poon

Such inconsistency would then lead to redundancy in activity labels, which refer to labels that have different syntax but share the same behaviours.

Detecting and Understanding Branching Frequency Changes in Process Models

no code implementations19 Mar 2021 Yang Lu, Qifan Chen, Simon Poon

In this paper, we propose a method which takes both event logs and process models as input and generates a choice sequence for each exclusive choice in the process model.
