D2I Lab

D2I Lab

We are a CS research group at Georgia Tech building next generation data analytics systems and interfaces. We are part of the Georgia Tech database group.

Welcome!

The world is increasingly driven by data, but turning large amounts of raw data into a few actionable insights often requires a team of well-trained engineers. The goal of the D2I lab (part of the Georgia Tech database group) is to 1) design and build systems and tools to help simplify data science at scale for non-experts and 2) train world-class researchers.

Our research focuses on building high-performance, user-friendly data systems to enable next-generation AI applications. Current research directions include:

  • Analytics over unstructured data
    • Video Labeling (e.g., SketchQL)
    • Image Understanding (e.g., VCR)
  • Data Infrastructure for AI:
    • Data preprocessing and cleaning for ML (e.g., LOTUS, DiffPrep)
    • Checkpointing for DL training (e.g., Inshrinkerator)
    • Vector databases and RAG systems
