1Productivity
If conventional AI/ML model monitoring methods are used, then drift detection capability is provided, but significant human intervention is required and efficiency is low
Solution Approach 1:
The system performs self-diagnosis by automatically detecting drift through pre-model and post-model analyses, identifying root causes without human intervention, and executing self-remediation through online model modification. The AI/ML system monitors its own performance and corrects drift autonomously, eliminating the need for manual monitoring and intervention.
Solution Approach 2:
The system performs preliminary drift detection through pre-model analysis that calculates metrics based on input data variance before the model makes predictions. This early detection allows the system to identify potential drift issues and prepare remediation actions in advance, improving efficiency by preventing drift from affecting model output.
2Extent of automation
If drift detection and remediation is performed manually, then some level of monitoring is achieved, but the process is inefficient and cannot operate autonomously
Solution Approach 1:
The system implements continuous feedback loops where post-model analysis calculates metrics based on prediction results and compares them against established norms. When drift is detected, the system feeds this information back to the model modification component, which automatically adjusts the model parameters. This closed-loop feedback mechanism enables autonomous remediation without manual intervention.
Solution Approach 2:
The system performs preliminary identification of root causes using causal methods before full remediation is executed. By analyzing the relationship between input data characteristics and drift patterns, the system pre-determines the appropriate remediation actions, enabling faster automated response when drift occurs.
3Measurement precision
If comprehensive drift analysis is performed, then root cause identification accuracy is improved, but system complexity increases
Solution Approach 1:
The system segments the drift analysis process into distinct components: pre-model analysis that examines input data variance, post-model analysis that evaluates prediction results, and causal analysis that identifies root causes. Each segment focuses on a specific aspect of drift detection, maintaining manageable complexity while achieving comprehensive analysis through the combination of segmented components.
Solution Approach 2:
The system performs partial analysis by focusing only on the most relevant metrics for drift detection rather than analyzing all possible data aspects. The pre-model analysis calculates specific metrics based on input data variance, and post-model analysis focuses on prediction result variations, providing sufficient accuracy for root cause identification without the complexity of exhaustive analysis.

AI summary
Embodiments of systems and methods for enhanced drift remediation with causal methods and online model modification are described. In some embodiments, an Information Handling System (IHS) may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the IHS to: detect drift in an Artificial Intelligence (AI) or Machine Learning (ML) model configured to make a prediction or a causal reasoning graphical or structural inference based upon input data, identify a root cause of the drift, and tag the input data with an indication of the root cause.
