Solution Overview

Problem

Existing computational models are either too complex to comprehend or too restrictive, often leading to overfitting in real-world applications due to spurious correlations in training data, resulting in inaccurate and unreliable predictions.

Innovation Solution

A method of generating a structural model architecture using a causality map that includes variables, relations, and constraints to create a transparent, flexible, and specified model that can predict output variables, utilizing neural networks, causal Bayesian networks, or decision trees, and optimizing the model with training data to prevent overfitting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If densely connected deep neural networks are used to learn intricate patterns, then prediction accuracy is improved, but model transparency and comprehensibility deteriorate

Engineering Contradiction:
Improveprediction accuracyVSAvoidmodel transparency
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the model architecture into distinct components: a structured representation layer that maintains interpretability and a prediction layer that captures complex patterns. This segmentation allows different parts of the system to specialize in transparency versus accuracy, resolving the contradiction between these two requirements.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary structured representation that acts as a bridge between interpretable features and complex predictions. This intermediary maintains the causal structure and variable relationships while enabling the model to learn intricate patterns, thus preserving transparency while improving accuracy.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If simple transparent models like linear regression are used, then model comprehensibility is improved, but predictive performance deteriorates

Engineering Contradiction:
Improvemodel transparencyVSAvoidpredictive performance
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent segments the modeling task into a structured representation component that provides transparency and a prediction component that delivers performance. This allows the system to combine the strengths of simple transparent models with the capabilities of complex predictive models.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a composite model architecture that combines interpretable structured representations with powerful predictive capabilities. This composite structure integrates the benefits of both simple transparent models and complex high-performance models, achieving both comprehensibility and predictive accuracy.

Inventive Principle:
Principle #40Composite materials

3Productivity

If models are trained on real-world data with spurious correlations, then training speed is improved, but model reliability deteriorates due to overfitting

Engineering Contradiction:
Improvetraining speedVSAvoidmodel robustness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent applies preliminary anti-action by pre-defining the structured causal relationships and constraints before training on real-world data. This pre-structure prevents the model from learning spurious correlations during training, countering the harmful effect of overfitting before it can occur while still allowing efficient training.

Inventive Principle:
Principle #9Preliminary anti-action

Solution Approach 2:

The patent incorporates feedback mechanisms through structured constraints that guide the learning process. The model receives feedback from the structured representation about which patterns are causally valid, preventing it from overfitting to spurious correlations in the training data while maintaining training efficiency.

Inventive Principle:
Principle #23Feedback
