Core Concepts
DAGnosis leverages structures to accurately flag data inconsistencies and provide localized insights, improving downstream performance.
Abstract
1. Introduction
- Data quality crucial for machine learning.
- Interest in data-centric AI for systematic evaluation.
- Inconsistencies in new data a key challenge.
- Importance of identifying inconsistencies for reliable performance.
2. Tabular Data and Sparse Connections
- Tabular data common in high-stake settings.
- DAGnosis evaluates samples based on structure, not individual dimensions.
- Provides precise analysis by considering sample structure.
3. DAGnosis: Identifying Inconsistencies Using Structures
- DAGnosis addresses flagging inconsistencies in tabular data.
- Leverages structures modeled as DAGs for accurate detection.
- Provides localized instance-wise conclusions for flagged inconsistencies.
4. Experiments
- DAGnosis accurately flags inconsistencies in synthetic data.
- Effective even with imperfect DAGs, ensuring robust performance.
- Localization of inconsistencies improves downstream accuracy.
- Case study demonstrates DAGnosis' ability to localize inconsistencies.
5. How to Use DAGnosis Step-by-Step
- Dataset construction with UCI Adult income data.
- DAG discovery using the PC algorithm.
- Flagging inconsistencies and localizing causes.
- Understanding inconsistencies with Dtrain.
- Contrasting with Data-SUITE's limitations.
6. Discussion
- Future directions in applying structures to other data modalities.
