2026-09-10 - VLDB26

We were involved in several workshop [1][2], demo [3][4] and research papers [5] at VLDB. This was the first conference attendance and presentation for Rubab and the first conference for Vinny.

TaDA!

Rubab her work on transformation search at https://tabular-data-analysis.github.io/tada2026/ workshop [1]. Initial results demonstrated several orders-of-magnitude speed-up for the AutoJoin system which discovers transformations to join two input columns.

Demos

Our two demos ended up side-by-side.
