Solution Overview

Problem

Current methods for regulating AI bots require large amounts of data and human feedback to ensure appropriate responses, which is not feasible in data scarce settings.

Innovation Solution

A system and method for generating training data using synthetic queries and responses based on rules, aggregating these responses to train a preference model, and fine-tuning an SFT model to provide real-time, rule-compliant responses.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If large amounts of data and human feedback are used to train AI bots, then the AI bot can generate correct and compliant responses, but the system becomes infeasible in data scarce settings

Engineering Contradiction:
Improveresponse correctnessVSAvoiddata quantity
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent uses synthetic data generation to create copies of training data that mimic real customer interactions. The system generates synthetic queries and responses that replicate the characteristics of real data, allowing the model to be trained without requiring actual customer interaction data. This copying approach enables reliable training in data scarce environments.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces an intermediary data generation system that bridges the gap between real data scarcity and training requirements. The system uses a data generation model that creates synthetic training data based on templates and patterns, serving as a mediator that provides sufficient training material without direct access to real customer data.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If human feedback is required to regulate AI bots, then the AI bot can be ensured to follow codes of conduct, but the process becomes complex and resource-intensive

Engineering Contradiction:
Improvecode of conduct complianceVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements self-service regulation where the AI bot trains itself on synthetic data that encodes codes of conduct. Instead of requiring continuous human feedback and intervention, the system generates compliant responses autonomously by learning from pre-generated synthetic training data that incorporates regulatory guidelines.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent applies preliminary action by pre-generating synthetic training data that incorporates codes of conduct before the AI bot needs to operate. The regulatory guidelines are embedded in the synthetic data during the training phase, allowing the model to learn compliance rules in advance without requiring real-time human supervision or feedback during operation.

Inventive Principle:
Principle #10Preliminary action

3Quantity of substance

If synthetic data is generated using multiple models, then training data can be created in data scarce settings, but the process requires aggregation of multiple models

Engineering Contradiction:
Improvetraining data quantityVSAvoidmodel aggregation complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent merges multiple models into a unified data generation system. The data generation model combines template-based generation, pattern recognition, and response synthesis into a single integrated system that produces synthetic training data. This merging approach simplifies the architecture by consolidating multiple functions into one cohesive model that efficiently generates diverse training material.

Inventive Principle:
Principle #5Merging (Combining)
