Solution Overview

Problem

Existing AI pipelines face inefficiencies due to the processing of invalid input data, leading to erroneous outputs and unnecessary resource consumption, as traditional approaches lack real-time validation mechanisms to detect and correct anomalies.

Innovation Solution

Implementing a real-time data validation mechanism within AI pipelines that monitors input data against predefined models, pauses processing upon detecting anomalies, retrieves or generates corrective data, and resumes operations from the paused location, ensuring only valid data is processed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real-time data validation is implemented in AI pipelines, then output reliability is improved, but device complexity increases

Engineering Contradiction:
Improveoutput reliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary validation of input data against the training data model before AI processing occurs. By checking data validity in advance and pausing execution when invalid data is detected, the system prevents erroneous outputs without requiring complex post-processing validation mechanisms.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary validation layer that sits between data input and AI model processing. This intermediary component compares incoming data against the training data model and either allows passage or triggers a pause, acting as a mediator that simplifies the overall system architecture while ensuring data quality.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Manufacturing precision

If validation mechanisms are added to detect invalid input data, then manufacturing precision is improved, but device complexity increases

Engineering Contradiction:
Improvedata processing precisionVSAvoiddevice complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system creates a copy or model of the training data structure that can be used for validation purposes. By comparing incoming data against this copied model rather than implementing complex validation logic, the system achieves high data processing precision with minimal additional complexity.

Inventive Principle:
Principle #26Copying

3Loss of time

If the AI pipeline pauses to retrieve valid data, then loss of time is reduced, but productivity decreases

Engineering Contradiction:
Improvetime lossVSAvoidproductivity
Core Design Contradiction:
Loss of timeVSProductivity

Solution Approach 1:

When invalid data is detected, the system skips ahead to retrieve valid data from alternative sources or correct the data, rather than processing the invalid data through the entire pipeline. This skipping approach minimizes time loss by avoiding wasted processing steps while maintaining productivity through automated recovery.

Inventive Principle:
Principle #21Skipping (Rushing through)

4Reliability

If computational resources are used to validate input data, then reliability is improved, but use of energy increases

Engineering Contradiction:
Improveoutput reliabilityVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The validation mechanism performs only the necessary comparisons against the training data model - checking key structural and format elements rather than exhaustive analysis. This partial validation approach provides sufficient reliability to prevent erroneous outputs while minimizing unnecessary energy consumption from over-validation.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

An example operation may include one or more of executing an artificial intelligence (AI) pipeline including an AI model via a software application, storing a token data model of the AI model via a storage of the software application, receiving input data via the AI pipeline of the software application, converting the input data into tokens via execution of a tokenizer within the AI pipeline on the input data, determining whether the tokenizer is valid based on a comparison of the tokens and the token data model of the AI model, and continuing execution of the AI pipeline of the software application based on whether the tokenizer is valid.
