- Abstract summary: This paper introduces Processes-As-Movies (PAM), a technique that provides a middle ground between predictive monitoring.
It does so by capturing declarative process constraints between activities in various windows of a process execution trace.
Various recurrent neural network topologies tailored to high-dimensional input are used to model the process model evolution with windows as time steps.

- Abstract: The field of predictive process monitoring focuses on modelling future
characteristics of running business process instances, typically by either
predicting the outcome of particular objectives (e.g. completion (time), cost),
or next-in-sequence prediction (e.g. what is the next activity to execute).
This paper introduces Processes-As-Movies (PAM), a technique that provides a
middle ground between these predictive monitoring. It does so by capturing
declarative process constraints between activities in various windows of a
process execution trace, which represent a declarative process model at
subsequent stages of execution. This high-dimensional representation of a
process model allows the application of predictive modelling on how such
constraints appear and vanish throughout a process' execution. Various
recurrent neural network topologies tailored to high-dimensional input are used
to model the process model evolution with windows as time steps, including
encoder-decoder long short-term memory networks, and convolutional long
short-term memory networks. Results show that these topologies are very
effective in terms of accuracy and precision to predict a process model's
future state, which allows process owners to simultaneously verify what linear
temporal logic rules hold in a predicted process window (objective-based), and
verify what future execution traces are allowed by all the constraints together
(trace-based).

Monitoring models to change [15.29342790344802]
Predictive Process Monitoring techniques typically construct a predictive model based on past process executions, and then use it to predict the future of new ongoing cases.
This can make Predictive Process Monitoring too rigid to deal with the variability of processes working in real environments.
We evaluate the use of three different strategies that allow the periodic rediscovery or incremental construction of the predictive model.
