Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional data processing methodologies are used to handle large datasets, then data storage and collection capabilities are maintained, but data quality deteriorates due to anomalies affecting predictions and analytics
Solution Approach 1:
The system performs preliminary anomaly detection and remediation actions before data is used for analytics and predictions. By proactively identifying anomalies through statistical checks and machine learning models, and automatically remediating them by replacing with expected values, the system ensures data quality is maintained before downstream processes consume the data, resolving the contradiction between handling large data volumes and maintaining data reliability
Solution Approach 2:
The system implements feedback mechanisms where anomaly detection results trigger automatic remediation actions. The anomaly detection module continuously monitors data quality metrics and feeds this information back to the remediation module, which adjusts its remediation strategies based on the detected anomaly patterns. This closed-loop feedback system maintains data quality while processing large datasets by dynamically responding to quality issues as they arise
2Reliability
If manual intervention is used for data quality management, then data accuracy can be improved, but resource efficiency deteriorates due to increased human effort and time consumption
Solution Approach 1:
The system implements self-service automation where the data remediation system independently detects anomalies, determines appropriate remediation actions, and executes corrections without human intervention. The machine learning models automatically identify anomaly patterns and the system autonomously replaces anomalous values with expected values derived from historical data or statistical models, maintaining data accuracy while eliminating the need for manual data quality management efforts
Solution Approach 2:
The system replaces manual mechanical processes of data quality review and correction with automated computational processes. Machine learning algorithms and statistical analysis tools substitute for human analysts in detecting and remediating anomalies, using computational power to process and correct data at scales and speeds that manual processes cannot achieve, thereby maintaining accuracy while dramatically improving resource efficiency
3Difficulty of detecting and measuring
If human experts are deployed for data quality management, then complex anomaly detection can be achieved, but cost and time consumption increase significantly
Solution Approach 1:
The system replaces expert human analysis with sophisticated machine learning models and automated statistical analysis tools that can detect complex anomaly patterns. These computational systems use advanced algorithms including isolation forests, autoencoders, and statistical process control to identify subtle anomaly patterns that would require expert human knowledge, executing these complex detections automatically and instantaneously without the time consumption associated with manual expert review
Solution Approach 2:
The system dynamically adjusts detection parameters and thresholds based on historical data patterns and learned anomaly characteristics. By changing detection sensitivity parameters, statistical thresholds, and model configuration settings automatically based on data characteristics, the system achieves expert-level detection capability while maintaining efficient automated operation without requiring manual parameter tuning by experts
4Productivity
If automated remediation is implemented, then productivity is improved by reducing manual effort, but system complexity increases due to the need for AI/ML components
Solution Approach 1:
The system segments the data quality management process into distinct modular components: data ingestion module, statistical check module, anomaly detection module (with separate algorithms for different anomaly types), expected value generation module, and remediation module. Each component performs a specific function and can be independently configured and maintained. This segmentation manages system complexity by breaking down the automated remediation system into manageable, specialized modules while maintaining high operational efficiency through their coordinated operation
Solution Approach 2:
The system introduces intermediary components such as expected value models and anomaly scoring mechanisms that mediate between raw data and remediation actions. These intermediary layers process and transform data in standardized ways, providing a buffer that simplifies the overall system architecture. The intermediaries convert diverse data types into standardized representations that can be processed by remediation logic, managing complexity while enabling automated high-productivity operation
Data Source
AI summary
An Artificial Intelligence (AI)-based data remediation system accesses analyzes a dataset for identification and remediation of anomalies including missing values and outliers. Based on the attributes associated with the anomalies, the dataset is initially processed via statistical checks for identifying if the dataset includes one of point anomalies, contextual anomalies and time trend anomalies. Based on the type of anomalies various machine learning (ML) based techniques can be employed for identification of the anomalous data points. Expected values are generated. The anomalous data points are replaced with the expected values for the generation of a transformed dataset.
