Almost Optimal Universal Lower Bound for Learning Causal DAGs with Atomic Interventions

AISTATS 2022poster

A well-studied challenge that arises in the structure learning problem of causal directed acyclic graphs (DAG) is that using observational data, one can only learn the graph up to a "Markov equivalence class" (MEC). The remaining undirected edges have to be oriented using interventions, which can be…

Conditional Generative Model Based Predicate-Aware Query Approximation

AAAI 2022technical

The goal of Approximate Query Processing (AQP) is to provide very fast but "accurate enough" results for costly aggregate queries thereby improving user experience in interactive exploration of large datasets. Recently proposed Machine-Learning-based AQP techniques can provide very low latency as qu…
