Embedded Metadata in ML Artifacts for Decentralized Governance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing MLOps implementations are centralized, leading to complex and expensive infrastructure, decoupled metadata storage, and loss of governance information due to isolated models, resulting in chain of custody issues and unreasonably long deployment times.
Innovation Solution
Embed metadata directly within machine learning artifacts, creating an audit trail by generating, encoding, and storing metadata within the artifact structure, allowing for automated access and use across frameworks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If centralized control is used for MLOps, then coordination and governance are improved, but infrastructure complexity and cost increase significantly
Solution Approach 1:
The patent extracts metadata from centralized storage and embeds it directly within the model artifact itself. This allows governance information to travel with the model through the pipeline without requiring centralized coordination, reducing infrastructure complexity while maintaining governance integrity.
Solution Approach 2:
The model artifact becomes self-contained with its own embedded metadata, enabling it to carry its own governance information and provenance data independently. This self-service approach eliminates dependency on centralized metadata stores and reduces infrastructure requirements.
2Adaptability or versatility
If metadata is stored separately from artifacts, then storage flexibility is improved, but chain of custody information is lost when models are isolated
Solution Approach 1:
The patent merges metadata and model artifacts into a single unified structure. By embedding metadata directly within the artifact, the system ensures that governance information and chain of custody data remain attached to the model throughout the pipeline, preventing information loss while maintaining storage flexibility.
Solution Approach 2:
The metadata is nested within the model artifact structure, creating a hierarchical organization where governance information is contained within the artifact itself. This nested structure allows the metadata to travel with the model while maintaining organizational flexibility.
3Reliability
If centralized metadata stores are used, then centralized governance is improved, but deployment time increases due to infrastructure tasks
Solution Approach 1:
The patent extracts the dependency on centralized metadata stores and replaces it with self-contained embedded metadata. This eliminates the time-consuming infrastructure tasks of querying and coordinating with centralized stores, accelerating deployment while maintaining governance control through the embedded metadata.
4Adaptability or versatility
If separate metadata stores are used, then storage independence is improved, but integration complexity increases across pipeline components
Solution Approach 1:
The patent merges metadata and artifacts into a single unit, eliminating the need for separate metadata stores. This unified approach reduces integration complexity across pipeline components while maintaining storage independence, as each artifact carries its own metadata without requiring external storage infrastructure.
Data Source
AI summary
A method for injecting metadata into an existing artifact is described. The method generates metadata related to an existing artifact having a predetermined structure and encodes the metadata in accordance with the predetermined structure. The encoded metadata is embedded within the existing artifact in accordance with the predetermined structure and is delineated within the predetermined structure as one or more individual records. The artifact, including embedded metadata, is stored within a storage entity and is accessible to processes related to the artifact. Additional records may be generated and embedded over time, thus creating a timeline if event related to the artifact.
