Table 4:

Summary of limitations of prior work when applied towards the completion problem. ICARUS addresses all 3 features.

System	Direct Edits	Guides Edits	Generalizes Edits	Limitations with respect to Data Completion
Falcon	✓	×	✓	Does not guide the user on edits.
SampleClean	×	×	✓	Addresses duplication and value errors for aggregate queries only. Does not fill in incomplete datasets.
Data Imputation & Holoclean	×	×	×	Low precision or recall, as shown in Section 4.4 and 4.6.3, since limited evidence in the data for missing values.
Transformational Edits -Trifacta, Potter’s Wheel, Polaris	✓	×	✓	While these systems generalize edits based on transforms, they do not guide users on effective transforms.
Interactive Learning - ActiveClean, Guided Data Repair	×	✓	✓	Suggests rules based on underlying models, which is not applicable when specific data instances are missing.
