Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the data science team focuses on maximizing model accuracy (F1 score), then the detection accuracy improves, but the overall pipeline performance deteriorates due to increased time and resource consumption
Solution Approach 1:
The system dynamically adjusts pipeline configuration based on performance goals. The optimization module allows the pipeline to adapt its structure, tasks, and parameters by simulating different configurations and selecting the optimal one that balances accuracy and performance requirements
Solution Approach 2:
The system changes multiple parameters simultaneously including pipeline structure, task configuration, data sources, and model parameters. The optimization module evaluates different parameter combinations through simulation to find the configuration that achieves desired KPIs
2Reliability
If multiple simulations are run to produce the best possible results, then the detection quality improves, but the time and computational resources required increase
Solution Approach 1:
The system performs preliminary simulations and evaluations before final execution. The optimization module pre-assesses multiple pipeline configurations through simulated runs to identify the optimal configuration, avoiding the need to run extensive simulations during actual detection operations
Solution Approach 2:
The system automatically optimizes its own pipeline configuration without requiring extensive manual simulation. The optimization module self-adjusts the pipeline by evaluating configurations and selecting the optimal one based on desired KPIs, reducing the time and resources needed for manual tuning
3Measurement precision
If the pipeline includes multiple data sets, pre-processing, clean-up, filtering, and transformation tasks, then the detection accuracy improves, but the pipeline complexity increases
Solution Approach 1:
The optimization module extracts and removes unnecessary or redundant tasks from the pipeline. By evaluating the contribution of each task to the desired KPIs, the system eliminates tasks that have minimal impact, thereby reducing pipeline complexity while maintaining detection accuracy
Solution Approach 2:
The system segments the pipeline into distinct, manageable tasks and evaluates each independently. This allows for selective optimization where only critical segments are maintained or enhanced, reducing overall complexity while preserving necessary processing steps
4Productivity
If the pipeline is optimized for desired KPIs including time and resource constraints, then the overall performance improves, but the model accuracy may be reduced
Solution Approach 1:
The system adjusts model parameters and configuration settings to achieve the desired balance between performance and accuracy. The optimization module modifies parameters such as sampling rates, threshold values, and model complexity to meet KPI requirements while maintaining acceptable detection accuracy
Solution Approach 2:
The system applies partial optimization by focusing on critical pipeline components that have the greatest impact on performance. Rather than optimizing every aspect equally, the system concentrates resources on key areas, achieving desired KPIs without requiring full optimization that would compromise accuracy
