Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If feature extraction is performed to reduce dimensionality, then processing efficiency is improved, but information loss may occur
Solution Approach 1:
The system performs preliminary actions by collecting and storing feature metadata before feature extraction occurs. This metadata includes information about feature sources, transformations, and relationships, which is preserved throughout the dimensionality reduction process to prevent information loss while improving processing efficiency.
Solution Approach 2:
The system implements feedback mechanisms by evaluating features and model results, then using this evaluation information to refine future feature extraction and selection processes. This iterative feedback loop ensures that dimensionality reduction maintains information quality while improving processing efficiency.
2Reliability
If feature selection is performed to identify relevant features, then model performance is improved, but computational complexity increases
Solution Approach 1:
The system performs preliminary actions by pre-collecting and organizing feature metadata that describes feature relevance, sources, and transformations. This pre-organized metadata enables more efficient feature selection processes that maintain high model performance while reducing computational complexity during execution.
Solution Approach 2:
The feature metadata acts as an intermediary between the raw data and the feature selection process. This intermediary layer provides structured information about features, enabling the system to make informed selection decisions that improve model performance without requiring excessive computational complexity.
3Productivity
If the input data set is reduced to improve processing speed, then productivity is improved, but feature quality may deteriorate
Solution Approach 1:
The system performs preliminary actions by collecting comprehensive feature metadata that captures the quality characteristics of features before reduction occurs. This metadata is preserved and used to guide the reduction process, ensuring that processing speed improves while feature quality is maintained through informed selection and transformation.
Solution Approach 2:
The system uses feedback from feature evaluation and model results to continuously refine the feature reduction process. This feedback mechanism ensures that processing speed improvements do not compromise feature quality, as the system adapts its reduction strategies based on actual feature performance.
Data Source
AI summary
In an approach for managing an open feature library, a processor collects feature metadata from a data source, the feature metadata being data related to features for training a machine learning model. A processor builds a feature pipeline for the features based on the collected feature metadata. The feature pipeline may be a set of defined and active features. A processor executes the feature pipeline including computing the features. A processor executes a machine learning model using the computed features. A processor evaluates the features and corresponding model results.
