Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If baseline machine learning models are used for event prediction, then the implementation is simple, but the prediction accuracy lags behind human expertise

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

Solution Approach 1:

The model is segmented into distinct functional components: an encoder for processing input data, a decoder for generating predictions, and a reward model for evaluating outcomes. This modular architecture allows each component to be optimized independently while working together to achieve human-level prediction accuracy.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

A reward model is introduced as an intermediary component that evaluates predicted outcomes and provides feedback signals. This reward mechanism mediates between the encoder-decoder prediction pipeline and the training objective, enabling the model to learn from human feedback and improve accuracy iteratively.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If more training data and complex processing are used, then prediction accuracy improves, but computational resources and time increase

Engineering Contradiction:
Improveprediction accuracyVSAvoidtraining time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The encoder is pre-trained on large corpora of text data before being fine-tuned for specific prediction tasks. This preliminary training allows the model to learn general patterns and relationships, reducing the time required for task-specific training while maintaining high prediction accuracy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The model employs continuous training loops where predictions are made, rewarded based on human feedback, and parameters are continuously adjusted. This continuous learning process allows the model to progressively improve accuracy without requiring complete retraining, thereby reducing overall training time.

Inventive Principle:
Principle #20Continuity of useful action

3Measurement precision

If human feedback is incorporated through reward models, then prediction accuracy approaches human expertise, but the system complexity increases

Engineering Contradiction:
Improveprediction accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

A feedback loop is established where the reward model evaluates predicted outcomes against human judgments and provides reward signals back to the training process. This feedback mechanism enables the model to learn from human expertise and progressively improve prediction accuracy to match human levels.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system uses the reward model to automatically evaluate and refine its own predictions without requiring constant human intervention. The model serves itself by using human feedback to adjust its parameters and improve performance autonomously, reducing the need for complex manual tuning.

Inventive Principle:
Principle #25Self-service

AI summary

Systems and methods for performing event prediction by: receiving an event prediction query, retrieving documents comprising information pertaining to the event prediction query, processing the documents to determine a relevance of the documents to the event prediction query, and generating an input article using the documents and the event prediction query. A decoder comprising a neural network then decodes the input vector into an event prediction outcome. The documents may be news articles. This core method may be supplemented in any one or more ways, such as by using a reward, using one or more large language models to summarize the training documents, and segmenting questions with numeric answers from those with non-numeric answers.
