Towards Causal Physical Error Discovery in Video Analytics Systems
Jinjin Zhao, Ted Shaowang, Stavos Sintos +1
Video analytics systems based on deep learning models are often opaque and brittle and require explanation systems to help users debug. Current model explanation system are very go…
JanusAQP: Efficient Partition Tree Maintenance for Dynamic Approximate Query Processing
Xi Liang, Stavros Sintos, Sanjay Krishnan
Approximate query processing over dynamic databases, i.e., under insertions/deletions, has applications ranging from high-frequency trading to internet-of-things analytics. We pres…
VizExtract: Automatic Relation Extraction from Data Visualizations
Dale Decatur, Sanjay Krishnan
Visual graphics, such as plots, charts, and figures, are widely used to communicate statistical conclusions. Extracting information directly from such visualizations is a key sub-p…
Version Reconciliation for Collaborative Databases
Nalin Ranjan, Zechao Shang, Aaron J. Elmore +1
We propose MindPalace, a prototype of a versioned database for efficient collaborative data management. MindPalace supports offline collaboration, where users work independently wi…
Combining Aggregation and Sampling (Nearly) Optimally for Approximate Query Processing
Xi Liang, Stavros Sintos, Zechao Shang +1
Sample-based approximate query processing (AQP) suffers from many pitfalls such as the inability to answer very selective queries and unreliable confidence intervals when sample si…
CIAO: An Optimization Framework for Client-Assisted Data Loading
Cong Ding, Dixin Tang, Xi Liang +2
Data loading has been one of the most common performance bottlenecks for many big data applications, especially when they are running on inefficient human-readable formats, such as…
