Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple per-event-type prediction models are trained separately, then prediction accuracy for each event type may be improved, but computational costs and storage requirements increase significantly

Engineering Contradiction:
Improveprediction accuracyVSAvoidcomputational cost
Core Design Contradiction:
Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent combines multiple per-event-type prediction models into a single multi-event-type prediction model that processes multiple event types simultaneously. This merging approach reduces the total computational overhead and storage requirements while maintaining prediction accuracy through a unified model architecture that handles diverse event types in one training session.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent creates a universal prediction model that can handle multiple event types through a single model instance. This multi-functional model uses event-type identifiers and prospective timeframes to adaptively predict different event types without requiring separate specialized models for each event, thereby reducing computational and storage costs.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Measurement precision

If multiple per-event-type prediction models are trained separately, then prediction accuracy for each event type may be improved, but storage requirements increase due to multiple model instances

Engineering Contradiction:
Improveprediction accuracyVSAvoidstorage requirements
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent merges multiple event-type specific models into one consolidated multi-event-type model. This single model stores shared parameters and event-type specific parameters in a unified structure, significantly reducing the total storage footprint compared to maintaining separate model instances for each event type while preserving the ability to accurately predict each event type.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If multiple training sessions are conducted for per-event-type models, then comprehensive coverage of different event types is achieved, but training time and computational resources are multiplied

Engineering Contradiction:
Improveevent type coverageVSAvoidtraining time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent combines multiple training sessions into a single training process that handles multiple event types simultaneously. The unified model is trained on diverse training data spanning multiple event types in one session, using event-type identifiers to differentiate between event types during training, thereby achieving comprehensive event type coverage without multiplying training time.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent incorporates event-type identifiers and prospective timeframes into the training data structure from the beginning, allowing the model to learn event-type specific patterns and temporal relationships in advance during a single training session. This preliminary structuring of training data enables the model to adapt to multiple event types without requiring sequential training sessions.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If repeat-occurrence training data fields are included in training, then model robustness may be improved, but prediction accuracy for first-occurrence events deteriorates due to data contamination

Engineering Contradiction:
Improvemodel robustnessVSAvoidfirst-occurrence prediction accuracy
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The patent segments the training data into distinct subsets based on event occurrence type (first-occurrence vs. repeat-occurrence). By filtering and separately processing these data segments, the model learns to distinguish between first-occurrence and repeat-occurrence patterns without contamination, improving first-occurrence prediction accuracy while maintaining robustness through comprehensive training on both data types.

Inventive Principle:
Principle #1Segmentation

AI summary

There is a need for more effective and efficient prediction data analysis. This need can be addressed by, for example, solutions for performing first-occurrence multi-disease prediction. In one example, a method includes determining a per-event-type loss value for each event type of a group of event types; determining a cross-event-type loss value based at least in part on each per-event-type loss value; training a multi-event-type prediction model based at least in part on the cross-event type loss value; generating a first-occurrence prediction based at least in part on the multi-event-type prediction model, wherein the first occurrence-prediction comprises a first-occurrence prediction item for each event type of the group of event types; and performing one or more prediction-based actions based at least in part on the first-occurrence prediction.
