Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual processes are used for data ingestion, processing, and model development, then flexibility and control are maintained, but development time and complexity increase significantly
Solution Approach 1:
The system performs preliminary actions by automatically ingesting sensor data, generating training data, and preparing datasets before the data scientist needs them. This includes automatic data cleaning, augmentation, and validation processes that prepare the data in advance for model training, eliminating manual preprocessing steps and reducing overall development time.
Solution Approach 2:
The system creates copies of training data through automated augmentation techniques, generating multiple variations of sensor data by applying transformations such as noise addition, sensor failures, and environmental condition variations. This allows the model to be trained on diverse scenarios without requiring additional real-world data collection, significantly reducing development time while maintaining manual oversight.
2Adaptability or versatility
If multiple disconnected tools are used for model development, then specialized functionality is available, but system complexity and integration effort increase
Solution Approach 1:
The system merges multiple disconnected tools into a single integrated platform that combines data ingestion, processing, augmentation, validation, and model training capabilities. This unified system eliminates the need to switch between multiple external tools while maintaining specialized functionality for each task through modular components within the integrated architecture.
Solution Approach 2:
The system provides universal functionality by enabling a single platform to perform multiple tasks across the entire machine learning development lifecycle. It can ingest sensor data, process and clean data, augment training datasets, validate data quality, and train models, replacing multiple specialized tools with one multi-functional system that reduces integration complexity.
3Reliability
If extensive manual data processing is performed, then data quality can be ensured, but the process becomes time-consuming and error-prone
Solution Approach 1:
The system implements automated feedback loops that continuously validate data quality during the processing and augmentation stages. Quality metrics are automatically calculated and compared against predefined thresholds, with the system providing feedback to adjust processing parameters or flag issues for review. This automated quality assurance maintains high data standards while eliminating manual checking and reducing processing time.
Solution Approach 2:
The system performs self-service data processing by automatically cleaning, validating, and augmenting sensor data without requiring manual intervention. The automated pipelines handle data quality assurance tasks independently, including detecting and correcting errors, filtering invalid data, and generating augmented datasets, thereby maintaining reliability while dramatically increasing processing speed and reducing human error.
