Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional risk assessment methods are used, then system simplicity is maintained, but prediction accuracy of future default events deteriorates
Solution Approach 1:
The patent segments the risk assessment process into multiple temporal intervals (first temporal interval for training, second temporal interval for validation, third temporal interval for prediction) and divides customer data into distinct datasets (first customer-specific dataset, second customer-specific dataset). This segmentation enables the system to process and analyze data in manageable chunks across different time periods, improving prediction accuracy while maintaining systematic organization.
Solution Approach 2:
The patent applies preliminary action by training the machine learning model in advance using customer data from a first temporal interval before validating it on a second temporal interval. This preparatory training phase allows the model to learn patterns and relationships in customer behavior data before actual prediction is needed, thereby improving prediction accuracy for future default events.
2Loss of time
If real-time data analysis is implemented, then prediction timeliness is improved, but computational resource requirements increase
Solution Approach 1:
The patent implements periodic action by analyzing customer data at discrete temporal intervals rather than continuously. The system processes data from a first temporal interval, validates on a second interval, and predicts for a third interval that is separated by a buffer interval. This periodic approach enables timely predictions while reducing computational resource consumption compared to continuous real-time analysis.
Solution Approach 2:
The patent applies partial action by using a buffer interval that separates the prediction temporal interval from the training temporal interval. This buffer interval allows the model to be trained on historical data and then validated on separate data before making predictions, ensuring computational efficiency while maintaining prediction timeliness through structured phased processing.
3Measurement precision
If adaptively trained machine learning models are used, then model accuracy is improved, but training time and data processing requirements increase
Solution Approach 1:
The patent applies preliminary action by conducting model training during a first temporal interval before validation and prediction phases. The model is trained in advance on customer data from the first temporal interval, allowing sufficient time for adaptive learning while ensuring the trained model is ready for deployment. This preliminary training approach improves model accuracy without delaying the actual prediction timeline.
Solution Approach 2:
The patent implements periodic action by structuring the machine learning process into distinct temporal phases: training on a first temporal interval, validation on a second temporal interval separated by a buffer interval, and prediction on a third temporal interval. This periodic structure allows the model to be adaptively trained and validated systematically, improving accuracy while managing training time through organized phased processing.
4Reliability
If buffer intervals are introduced between temporal intervals, then model validation reliability is improved, but overall processing time increases
Solution Approach 1:
The patent implements periodic action by introducing a buffer interval that separates the training temporal interval from the validation temporal interval. This buffer interval creates distinct periodic phases for training and validation, allowing the model to be properly validated on independent data without temporal overlap. The periodic structure improves validation reliability by ensuring data independence while managing processing time through structured scheduling.
Solution Approach 2:
The patent applies partial action by using a buffer interval that partially separates training and validation phases. This buffer interval provides sufficient separation to ensure model validation reliability through independent data testing, while not excessively extending the overall processing time. The partial separation achieves the necessary validation reliability without unnecessary time delays.
Data Source
AI summary
The disclosed embodiments include computer-implemented apparatuses and processes that dynamically predict future occurrences of events using adaptively trained artificial-intelligence processes and contextual data. For example, an apparatus may generate an input dataset based on first interaction data and contextual data associated with a prior temporal interval, and may apply an adaptively trained, gradient-boosted, decision-tree process to the input dataset. Based on the application of the adaptively trained, gradient-boosted, decision-tree process to the input dataset, the apparatus may generate output data representative of a predicted likelihood of an occurrence of an event during a future temporal interval, which may be separated from the prior temporal interval by a corresponding buffer interval. The apparatus may also transmit a portion of the generated output data to a computing system, and the computing system may be configured to generate or modify second interaction data based on the portion of the output data.
