Predictive Process Monitoring (PPM) is the use of data mining and machine learning to predict the future of ongoing business processes. This research focuses on two critical PPM tasks: predicting the Next Activity (NA) in a process and forecasting the Remaining Time (RT) until completion. Improving these predictions allows businesses to proactively manage resources, mitigate delays, and improve customer satisfaction by setting accurate expectations.
Parameter-Efficient Fine-Tuning (PEFT) is a set of techniques used to adapt massive pretrained AI models to new, specific tasks without the enormous cost of retraining the entire model. Methods like Low-Rank Adaptation (LoRA) or partial layer "freezing" modify only a small fraction of the model's parameters (often <1%). This makes specialization feasible for enterprises, drastically lowering computational costs and training time while retaining the power of the base model.
Direct Domain Adaptation represents a strategic departure from common LLM applications. Instead of converting structured process logs into conversational text for the LLM to read, this method adapts the LLM to understand the raw, structured data itself. This approach is more robust, avoids potential misinterpretations from text conversion, and trains the model on the true underlying patterns and syntax of business operations, leading to superior performance.

Next Activity & Time Prediction
Case Study: The Multi-Task Advantage in Process Monitoring
In traditional AI, predicting the next process step (a classification task) and the remaining time (a regression task) often requires two separate models or a complex, hard-to-tune multi-task model. The study shows that traditional Recurrent Neural Networks (RNNs) particularly struggle with this, often underfitting on the regression task when trained jointly.
However, the PEFT-adapted LLMs excelled. A single, fine-tuned LLM was able to simultaneously predict both the next activity and remaining time with high accuracy. This is a significant breakthrough for enterprise efficiency. Instead of deploying and maintaining multiple AI systems, a single, unified model can provide comprehensive process insights, reducing architectural complexity and operational overhead while delivering more accurate, holistic predictions.
Spotlight on LoRA: Unlocking Regression Performance
17% Error Reduction in Remaining Time Prediction (vs. MT-RNN)The research highlighted that Low-Rank Adaptation (LoRA) was uniquely effective for the difficult task of predicting remaining time. Because LLMs are fundamentally trained as next-token predictors (a classification task), they can struggle with regression. LoRA overcomes this by inserting new, small, trainable layers into the model, which can be specifically optimized for the regression task without disrupting the model's core knowledge. This results in significantly lower prediction errors compared to other methods.

Your AI Adaptation Roadmap
Implementing this advanced AI methodology is a strategic, phased process. Here’s a typical roadmap for transforming your process monitoring capabilities from reactive to predictive.
Phase 1: Process Baseline & Opportunity Analysis
Audit current business processes to identify high-value prediction targets. Consolidate relevant event logs and establish baseline performance metrics.
Phase 2: Data Structuring & Preparation
Clean, format, and structure historical event log data for direct consumption by an LLM, ensuring all necessary features are present and correctly encoded.
Phase 3: PEFT Implementation & Training
Select a suitable pretrained LLM and apply a PEFT method like LoRA. Train the model on your structured process data to create a specialized, domain-aware predictor.
Phase 4: Multi-Task Model Deployment & Integration
Deploy the single, unified model into a staging environment. Integrate its predictive outputs (Next Activity & Remaining Time) with your existing operational dashboards or workflow systems.
Phase 5: Performance Monitoring & Continuous Optimization
Monitor the model's predictive accuracy in a live environment. Establish a feedback loop to periodically retrain the model with new data, ensuring it adapts to evolving business processes.
Modernize Your Process Intelligence
