• Aug-2023: We will be presenting 4 papers at VLDB! Saibot brings differential privacy to task-based dataset search platforms, Joinboost trains decision trees, radom forests, and gradient boosted models within DBMSes faster than ML libraries like LightGBM and XGBoost, Pollock introduces a benchmark and grammar-based formalization for studying CSV loaders, and ConnectorX is the fastest way for DataFrame systems to load data from DBMSes. Excited to see folks in Vancouver!
• Jul-2023: Delighted to recieve a grant from Columbia’s Center of AI Technology to study differentially private dataset search with Rachel Cummings.
• May-2023: SIGMOD 2023 is next month! We have exciting work on a Data Interface Grammar, how to detect and avoid logical errors in semantic layers, CPU-GPU acceleration for In-DBMS machine learning, a suite of XTutor visualization libraries for data education, and the OM3 progressively encoded data structure for fast and massive-scale time series visualizations!
• Dec-2022: Zachary recieved the Columbia Data Science Institute’s Avanessian PhD fellowship!
• Sep-2022: IEEE VIS 2022 is next month! Excited to present our work on generating fully interactive interface from natural language questions at the nlviz workshop, our recommendations for how to write captions for data visualizations at the viscomm workshop, and our new formalism and interaction design for ad hoc comparisons at the main conference!
• Aug-2022: A nice Columbia Engineering article about our research to help insure African farmers from droughts and floods.
• Jun-2022: SIGMOD 2022 is this week! We are presenting 3 full papers, 1 DEEM workshop paper, 2 demos, and student research competition posters! We summarize this work in our SIGMOD 22 Blog post!
• Mar-2022: PI2 is the first system that generates fully interactive visualization analysis interfaces from queries. We are excited to present it at SIGMOD 2022!
• Feb-2022: Excited to have been recommended for tenure at Columbia University!
• Feb-2022: our paper View Composition Algebra for Ad hoc Comparisons was accepted to TVCG 2022 and will be presented at VIS later this year.
• Jan-2022: 2 more paper acceptances to SIGMOD 2022: our demo paper Interactive Interface Generation in Notebooks extends jupyter to automatically generate interactive analysis interfaces during SQL analysis, and our full paper Complaint-Driven Training Data Debugging at Interactive Speeds enables training data debugging by simply identifying errors in analytic results in milliseconds!
• Jan-2022: FLAWLESS VICTORY! Our mortal kombat-themed system, Reptile reformulates data cleaning as a top-down iterative process. It has been used in Zambia and Ethiopia to clean nation-wide farmer survey data in order to design their national drought insurance policies. Zachary will present it at SIGMOD 2022.
