Engineering Contradiction Analysis
1Reliability
If machine learning models are retrained frequently to keep pace with emerging trends, then the model's ability to detect current patterns improves, but the time and computational resources required increase significantly
Solution Approach 1:
The system performs preliminary actions by proactively retraining models on recent data before performance degradation occurs. The automated retraining pipeline continuously trains models on the most recent data subsets, ensuring models are updated with current patterns before they are needed for production, thus maintaining high accuracy without manual intervention delays.
Solution Approach 2:
The retraining process is segmented into manageable components: data subset selection (most recent data), model copying (challenger model creation), independent training, and automated evaluation. This segmentation allows parallel processing and reduces the time penalty of frequent retraining by breaking the monolithic retraining task into efficient, modular steps.
2Reliability
If manual retraining processes are used to maintain model accuracy, then model performance can be optimized, but significant manual effort from data science teams is required
Solution Approach 1:
The system implements self-service through automated model retraining and evaluation pipelines. The framework automatically selects recent data subsets, trains challenger models, evaluates performance against thresholds, and promotes successful models to production without requiring data science team intervention. This eliminates manual effort while maintaining model performance through continuous automated optimization.
Solution Approach 2:
The system incorporates feedback mechanisms where model performance is continuously evaluated against predefined thresholds and metrics. The automated evaluation process provides feedback on challenger model performance, triggering promotion to production only when performance criteria are met, ensuring model accuracy is maintained through systematic feedback-driven optimization without manual oversight.
3Use of energy by moving object
If model retraining is performed on longer time intervals to reduce computational overhead, then resource consumption decreases, but the model lags behind emerging trends and patterns
Solution Approach 1:
The system applies partial action by training models on selective subsets of recent data rather than complete historical datasets. This approach uses only the most relevant recent data (e.g., last 7-30 days) for retraining, reducing computational resources required while maintaining model update speed. The partial data approach is sufficient to capture emerging trends without the overhead of processing entire historical datasets.
4Adaptability or versatility
If freshly trained models are deployed frequently to capture emerging patterns, then operational relevance improves, but distribution shifts in output populations cause rules to receive significantly more or less actionable data
Solution Approach 1:
The system uses feedback mechanisms to detect and correct distribution shifts in model outputs. The rule optimization framework continuously monitors output populations from freshly trained models and automatically adjusts rules to normalize distributions, ensuring stable actionable data flow to operations. This feedback-driven optimization maintains operational relevance while compensating for distribution shifts through automated rule adjustments.
Solution Approach 2:
The system applies parameter changes by dynamically adjusting rule parameters (such as thresholds and scalers) in response to distribution shifts. When freshly trained models produce shifted output distributions, the framework automatically modifies rule parameters to normalize the output, maintaining reliable actionable data flow while preserving the adaptability benefits of frequent model updates.
