Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing prediction models struggle with maintaining accuracy due to the large volume and frequent changes in transactional data, making periodic retraining with old data risky and time-consuming, which can lead to inaccurate predictions.
Innovation Solution
Implementing a dynamic retraining process using real-time transaction data to continuously update the prediction model, ensuring that the relationships between influencing parameters and outcomes are re-established as patterns change, thereby maintaining model accuracy and relevance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the prediction model is trained periodically with historical transaction data, then the model can be updated to maintain prediction capability, but the training data becomes outdated and prediction accuracy deteriorates
Solution Approach 1:
The patent implements dynamic retraining by transitioning from static periodic training to continuous adaptive training. The system automatically retrains the prediction model when performance degradation is detected, ensuring the model adapts to changing transaction patterns in real-time rather than relying on fixed schedules, thus maintaining both accuracy and data freshness.
Solution Approach 2:
The system incorporates feedback mechanisms by continuously monitoring prediction performance and using this feedback to trigger retraining events. When prediction accuracy falls below thresholds or performance degradation is detected, the system automatically initiates retraining with fresh transaction data, creating a closed-loop system that maintains reliability without time loss.
2Measurement precision
If the prediction model is trained frequently with large volumes of transaction data, then prediction accuracy improves, but the training process becomes time-consuming and computationally intensive
Solution Approach 1:
The patent applies partial action by selectively using only the necessary portion of transaction data for retraining rather than processing entire historical datasets. The system identifies and uses relevant recent transactions that are most impactful for maintaining prediction accuracy, reducing training time while preserving measurement precision.
Solution Approach 2:
The system implements conditional periodic action by scheduling retraining based on performance metrics rather than fixed time intervals. Retraining occurs periodically only when needed - triggered by performance degradation detection - thus balancing accuracy requirements with time constraints by avoiding unnecessary full-scale training operations.
3Productivity
If the prediction model relies on old transaction data, then training computational load is reduced, but prediction reliability deteriorates due to outdated patterns
Solution Approach 1:
The system performs preliminary action by proactively monitoring prediction performance and detecting degradation trends before they significantly impact reliability. This early detection triggers timely retraining with fresh data, ensuring the model maintains reliability without requiring excessive computational resources on outdated data.
Solution Approach 2:
The patent changes the parameter of data recency by dynamically adjusting which transaction data is used for training based on performance requirements. Instead of using fixed historical windows, the system adapts data selection parameters to ensure sufficient data freshness while optimizing training efficiency, maintaining reliability without unnecessary computational burden.

AI summary
Various embodiments of systems and methods to dynamically retrain prediction models based on real time transaction data are described herein. In one aspect, real time application data and status data associated with an entity are obtained. The obtained application data is inputted to a prediction model to produce an assessment of a risk. The obtained status data with the assessed risk are compared. When the obtained payment status data does not match the determined risk, the prediction model is retrained.
