Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated annotation systems are used to improve efficiency, then productivity increases, but accuracy deteriorates
Solution Approach 1:
The dataset is segmented into multiple partitions (e.g., training set, validation set, test set) with specific constraints on label distribution. This segmentation allows the system to train automated annotators on one partition while validating on another, preventing data leakage and improving accuracy assessment.
Solution Approach 2:
The system changes the parameter of data distribution by ensuring that each partition has a specific distribution of metadata labels. This parameter change enables proper evaluation of automated annotation systems by ensuring training and validation data have appropriate label distributions.
2Reliability
If datasets are partitioned for training and validation, then accuracy improves, but device complexity increases
Solution Approach 1:
The partitioning system automatically assigns data samples to partitions based on metadata labels without requiring manual intervention. The system self-services by computing label distributions and automatically creating partitions that satisfy the specified constraints, reducing operational complexity.
Solution Approach 2:
The system uses parameter-based approaches where users specify desired label distributions as parameters, and the system automatically adjusts partition assignments to match these parameters. This parameter-driven approach simplifies the complexity of ensuring proper data distribution.
3Reliability
If manual annotation is used to ensure accuracy, then reliability improves, but productivity deteriorates
Solution Approach 1:
The annotation process is segmented into training phase (where manual annotations create training data) and validation phase (where automated systems perform annotation). This segmentation allows manual annotation to improve accuracy during training while automated systems handle the bulk of annotation work during validation, improving overall productivity.
Solution Approach 2:
Manual annotation is performed as a preliminary action to create the training dataset. Once this preliminary training data is available, the automated annotation system can be trained and subsequently used for the majority of annotation tasks, dramatically improving productivity while maintaining accuracy through the preliminary manual training.
Data Source
AI summary
A system includes a computing platform having processing hardware and a memory storing a software code. The processing hardware executes the software code to receive a dataset including at least some data samples having multiple metadata labels, and identify a partitioning constraint and a partitioning of the dataset into data subsets. The software code also executed obtains, for each metadata label, a desired distribution ratio based on the number of the data subsets and a total number of instances that each metadata label has been applied to the data samples, aggregates, using the partitioning constraint, the data samples into data sample groups, assigns, using the partitioning constraint and the desired distribution ratio for each of the metadata labels, each of the data sample groups to one of the data subsets, wherein each of the data subsets are unique, and trains, using one of the data subsets, a machine learning model.
