Engineering Contradiction Analysis
1Productivity
If traditional trial-and-error methods are used for hyperparameter tuning, then implementation simplicity is maintained, but productivity is reduced due to significant time and computational effort required
Solution Approach 1:
The patent divides the hyperparameter search space into multiple discrete search points that can be independently evaluated. Each search point represents a specific hyperparameter configuration that can be tested separately, allowing parallel exploration of different configurations without interfering with each other. This segmentation enables systematic coverage of the search space while maintaining implementation simplicity.
Solution Approach 2:
The system performs preliminary actions by pre-defining a comprehensive set of hyperparameter search points before the tuning process begins. This pre-planning of the search space allows the system to systematically explore all potential configurations without ad-hoc adjustments during execution, reducing iterative trial-and-error cycles and accelerating the overall tuning process.
2Manufacturing precision
If traditional hyperparameter tuning methods are used, then resource requirements are reduced, but manufacturing precision deteriorates due to suboptimal model performance
Solution Approach 1:
The patent introduces a parent-child process architecture as an intermediary mechanism to manage the complexity of hyperparameter tuning. The parent process coordinates the overall search strategy and resource management, while child processes execute individual hyperparameter configurations. This intermediary structure enables sophisticated parallel exploration without requiring complex distributed system infrastructure, thus achieving high model performance with manageable system complexity.
Solution Approach 2:
The system creates multiple copies of the training process running in parallel, each copy evaluating a different hyperparameter configuration. By replicating the training workflow across multiple processes rather than sequentially executing variations, the system achieves thorough exploration of the search space and identifies optimal configurations more efficiently, improving model performance without proportionally increasing system complexity.
3Measurement precision
If comprehensive hyperparameter search is performed, then measurement precision is improved, but loss of energy increases due to extensive computational exploration
Solution Approach 1:
The patent implements a strategy of performing partial exploration of the hyperparameter space by defining a finite set of search points that covers the most critical configurations. Rather than exhaustively searching every possible combination, the system selects a representative subset of search points that provides sufficient coverage to identify optimal hyperparameters. This partial action approach achieves thorough enough exploration for practical purposes while significantly reducing computational energy consumption compared to exhaustive search methods.
