Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If general purpose generative AI models are used, then they are highly capable in various natural language tasks, but they hallucinate and produce incorrect output responses to domain-specific questions
Solution Approach 1:
The patent segments the training data into domain-specific portions by crawling and collecting data from domain-relevant websites identified through expert input. This segmentation allows the model to specialize in specific domains while maintaining general capabilities, resolving the contradiction between versatility and domain accuracy.
Solution Approach 2:
The patent changes the parameter of training data composition by incorporating a significant portion of domain-specific crawled data alongside general-purpose data. This parameter adjustment enables the model to achieve both general capability and domain-specific accuracy by modifying the data mixture ratio.
2Quantity of substance
If unstructured textual data is collected from the web, then large amounts of data are available, but the data is noisy and requires heavy pre-processing
Solution Approach 1:
The patent applies preliminary action by implementing structured crawling with predefined schemas and validation rules before the main training data collection. This preliminary structuring reduces noise and organizes data in advance, significantly reducing the pre-processing complexity required for the bulk data collection.
Solution Approach 2:
The patent implements feedback mechanisms through validation rules and quality checks during the crawling process. Data that does not meet predefined quality criteria is filtered out or flagged for revision, creating a feedback loop that continuously improves data quality and reduces downstream pre-processing requirements.
3Productivity
If existing web crawling approaches are used, then systematic collection from webpages is possible, but they do not focus on obtaining domain-specific data based on expert input
Solution Approach 1:
The patent introduces domain experts as intermediaries between the crawling system and the data sources. Experts provide input on which websites and content types are relevant to specific domains, enabling the systematic crawler to efficiently collect domain-specific data while maintaining high productivity through automated processes.
4Loss of information
If LLMs process lengthy documents, then comprehensive information can be analyzed, but the context limits of finite tokens are insufficient
Solution Approach 1:
The patent segments lengthy documents into smaller chunks during the crawling and processing stage, organizing them into structured formats that can be processed within token limits while preserving comprehensive information through systematic segmentation and indexing.
Data Source
AI summary
Systems and methods for producing domain-specific data for training generative AI models as described herein systematically acquire, validate, and fine-tune AI models using domain-specific data. In embodiments, this comprises identifying seed documents, extracting keywords, performing refined searches, and scraping relevant content. The data is then pre-processed, chunked, and indexed. Using a retrieval-augmented generation approach, the system evaluates the quality and relevance of the data, ensuring efficient computational resource use and improved model training outcomes. By leveraging expert knowledge and systematic data validation, the accuracy and reliability of domain-specific AI models is enhanced.
