Process mining provides immense value for accelerating process transformations by unlocking data-driven insights from business activity logs. Leading organizations like BMW, Zurich Insurance, and Celonis itself leverage process mining to pinpoint process improvement opportunities with precision. However, as data volumes and process complexities scale exponentially, traditional process mining methodologies struggle to keep pace.
This is fueling the integration of machine learning capabilities to catapult process mining into a new era of intelligence. The field of machine learning process mining combines complementary strengths of AI and process analytics to deliver unprecedented levels of automation, dimensionality, and foresight.
In this comprehensive guide, we explore how the fusion of machine learning and process mining enables next-generation process excellence.
The Limitations of Conventional Process Mining
First, let‘s review fundamentals of traditional process mining. The methodology involves applying algorithms to event logs recording detailed activity from process executions in order to:
- Discover as-is process workflows
- Measure real-world process KPIs
- Identify process deviations and bottlenecks
- Compare variants across processes
This event data-driven approach provides complete visibility into processes unseen with other tools. It moves process understanding from theoretical process maps to empirical as-is observations.
However, as powerful as these capabilities are, traditional process mining also faces barriers, especially as data scale and process complexity intensify:
Data Volume Challenges
| Process Mining Pain Point | Machine Learning Solution |
|---|---|
| Excessive manual data wrangling for mining | Automated data pre-processing with ML data pipelines |
| Difficulty analyzing billions of process events | Distributed computing frameworks like Spark or Hadoop |
| Identifying insights within massive event datasets | ML pattern recognition and dimensionality reduction techniques |
Process Complexity Headaches
| Process Mining Pain Point | Machine Learning Solution |
|---|---|
| Modeling complex processes with long unstructured sequences | Sequence learning neural networks |
| Simplifying analysis of intricate process variants | Unsupervised ML clustering algorithms |
| Handling frequently evolving volatile processes | Online learning and adaptable ML models |
Facing such scales, conventional process mining struggles to deliver ROI and often requires add-on analytical tools. This complexity motivated the exploration of how machine learning could take process mining to the next level.
Augmenting Process Mining with Machine Learning
Machine learning refers to training AI models on historical data to uncover hidden insights and make data-driven predictions without explicit programming. ML provides tools to overcome exactly the volume and complexity constraints holding back process mining.
We will unpack how pairing popular ML approaches with process mining activates new realms of possibility:
| Machine Learning Technique | Process Mining Use Cases |
|---|---|
| Clustering algorithms like k-means and hierarchical clustering | Group event logs into behaviorally distinct process segments for simpler isolated analysis |
| Classification algorithms like random forests and logistic regression | Label process cases (e.g. as compliant/non-compliant) for targeted monitoring |
| Anomaly detection algorithms like isolation forests and autoencoders | Flag abnormal process executions with errors or bottlenecks |
| Reinforcement learning reward-optimization methods | Learn self-improving policies for automated process decision-making |
| Neural networks like LSTMs and Transformers for sequence learning | Discover complex end-to-end processes directly from low-structured event data |
Let‘s analyze some of these use cases to showcase the transformations machine learning ignites for next-gen process mining.
Revolutionizing Process Discovery with Neural Networks
Discovering full process maps from scattered event streams traditionally requires intense data wrangling and mining configuration tuning. Even then, spaghetti processes with myriad variants defeat algorithms focused on analyzing structured workflow loops.
This is where neural networks prove game-changing. Modern sequence learning models like long short-term memory networks (LSTMs) and Transformers can ingest disordered event sequences and directly output holistic process flowcharts.
Key strengths include:
- Remembering long-term dependencies – LSTMs avoid vanishing gradients using memory gates, learning links between early and late events.
- Attention mechanisms – Transformers pinpoint relevant events in context using multi-headed self attention.
- Transfer learning – Pre-trained models can transfer pattern knowledge to downstream process learning.
MyInvenio applies LSTMs for automated process discovery, reducing weeks of manual mining to hours. Fortia leverages Transformers to learn processes involving submissions, approvals, and human-in-the-loop decisions.
The benefits of such AI-based process charting include:
- 90% less time spent on data prep and algorithm tuning
- 40% more process details captured with end-to-end visibility
- Real-time process tracking by continually retraining models
By augmenting process discovery with neural networks, otherwise obscured processes become transparent and self-evolving.
Boosting Diagnostics with Anomaly Detection
While process mining delivers an xray into workflows, identifying root causes of observed performance degradation represents a pivotal next step.
Traditionally, this requires manual filtering of metrics and trace inspection to pinpoint offending components. When dealing with intricate processes and abundance of deviations, such troubleshooting grows infeasible.
This is where machine learning anomaly detection algorithms prove a game changer. Techniques like isolation forests, autoencoders, and multivariate probability density estimation can automatically:
- Detect outlier process instances with issues
- Flag specific abnormal events within traces
- Score severity of deviations from regular process patterns
Root causes bubble up as marked anomalies against baseline behavior. Data scientists at myInvenio developed a custom isolation forest algorithm discovering anomalies across process time series metrics with 96% accuracy:
Enriched with diagnostics intelligence, process mining evolves into an early warning radar on process disruptions. Breaches become visible before cascading into crises.
Predicting with Digital Twins
Viewing processes through a rearview mirror supplies vital insight but leaves leaders flying blind on emerging roadblocks.
By projecting processes into the future, predictive process mining enables scenario planning, capacity management, and proactive assurance. Machine learning superpowers such predictive capabilities.
Monte Carlo simulations leverage probabilistic ML models to:
- Generate a digital twin reflecting real process dynamics
- Run thousands of simulations while tweaking parameters
- Estimate spread of possible outcomes
The figure below illustrates a Monte Carlo simulation predicting order lead time distribution given process uncertainties:
Comparing prediction spread with targets highlights risks. Pre-emptive mitigations integrate into plans.
Reinforcement learning takes this further by enabling AI to autonomously optimize processes over time against business KPIs through trial-and-error. Fortia and Celonis execute such intelligent process redesign.
The result is forward-looking guidance instead of reactive responses.
Industry Use Cases Confirming the Value
The machine learning enhancements above represent just a subset of AI‘s potential for advancing process mining. Behind the algorithms, tangible value manifests through real-world implementations:
| Industry | Organization | Use Case | Outcomes |
|---|---|---|---|
| Financial Services | Large US Bank | Anomaly detection uncovering fraud | -$20M in fraud losses prevented |
| Logistics | Global Postal Provider | Monte Carlo forecasting for capacity planning | +12% on-time delivery improvement |
| Telecom | European Telco | Neural process discovery tracking network usage | -52% customer complaints |
| Retail | International Supermarket Chain | Reinforcement learning optimizing warehouse ops | +8% productivity improvement |
Across sectors, leading organizations realize hard ROI from machine learning process mining with use cases aligned to strategic objectives.
But to activate the full potential, focus on foundational elements proves critical…
