Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing AI systems generate fact hallucinations due to insufficient training data and lack of real-time verification, leading to inaccurate query results.
Innovation Solution
Implement a system with an AI validation server that tokenizes and indexes data, allowing real-time verification by comparing AI query responses to compressed blocks in a token database, using similarity scores to identify and correct fact hallucinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If AI systems use transformer models with attention mechanisms to generate content, then the system can process large amounts of training data and create coherent responses, but the system generates fact hallucinations due to insufficient training data and loss of original information during training
Solution Approach 1:
The system performs preliminary actions by tokenizing and compressing the original training data into a token database before the AI model generates responses. This pre-processed token database serves as a reference repository that the verification system can query to check factual accuracy of generated content, preventing hallucinations before they reach the user.
Solution Approach 2:
The patent introduces an intermediary verification system that acts as a mediator between the AI model and the user. This verification system compares the AI-generated responses against the pre-processed token database using similarity scoring, serving as a factual check that identifies hallucinations without interfering with the model's creative generation process.
2Adaptability or versatility
If the AI model is trained on very large databases of plain text, then the model can learn diverse patterns and relationships, but information is abstracted and lost in translation during the training process
Solution Approach 1:
The system creates a copy of the original training data in the form of a token database that preserves the raw textual information. Instead of relying solely on the abstracted knowledge embedded in the trained model weights, the verification system queries this preserved copy to fact-check responses, ensuring that original information is not lost despite the abstraction necessary for training.
3Reliability
If real-time verification is implemented by comparing AI responses to the original training data, then fact hallucinations can be identified, but it is not practical to contain all training data in the memory of a single computer
Solution Approach 1:
The system segments the verification process into two parts: (1) a pre-processing stage that tokenizes and compresses the training data into a compact token database, and (2) a real-time verification stage that queries this database. This segmentation allows the system to verify facts without needing to store all original training data in memory, as the token database provides a space-efficient representation.
Solution Approach 2:
The patent applies parameter changes by transforming the training data from its original form into a tokenized and compressed representation. This parameter transformation reduces the memory footprint while preserving the essential information needed for verification, enabling practical implementation of fact-checking systems.
4Reliability
If the system queries the token database to verify AI responses in real-time, then fact hallucinations can be detected, but the verification process requires additional time and computational resources
Solution Approach 1:
By performing the tokenization and compression of training data in advance (preliminary action), the system prepares the verification database so that real-time queries can be executed efficiently. This pre-processing eliminates the need for time-consuming data preparation during verification, reducing the time penalty associated with fact-checking.
Data Source
AI summary
An AI query response processed by an artificial intelligence (AI) module using a neural model is received as an input. The query response is compared to one or more tokenized facts of the compressed blocks at a data level. Comparing includes computing a similarity score of a vector derived from the tokenized query response to one or more vectors derived from the one or more tokenized facts. Responsive to a verification result failing to meet a similarity score threshold, it can be determined that a hallucination exists in the AI query response and a policy-based action, such as blocking the AI query response, can be taken. Responsive to the verification result meeting the similarity threshold, the AI query response can be allowed to proceed.
