UrbanTrace: LLM-Assisted Discovery and Semantics-Aware Integration of Spatial Data
Sonia Castelo, Eden Wu, Joao Rulff +3
Urban decision-making requires integrating heterogeneous spatial data. While current GIS tools handle geometric computation efficiently, they lack the semantic reasoning to guide c…
AgentTrails: Towards Trust and Reuse for Agentic Tasks
Eden Wu, Sonia Castelo, Yurong Liu +2
LLM-powered agents increasingly tackle complex tasks by invoking tools, querying databases, executing code, and manipulating intermediate artifacts. These agents follow trajectorie…
GPU-Powered Spatial Database Engine for Commodity Hardware: Extended Version
Harish Doraiswamy, Juliana Freire
Given the massive growth in the volume of spatial data, there is a great need for systems that can efficiently evaluate spatial queries over large data sets. These queries are noto…
AlphaD3M: Machine Learning Pipeline Synthesis
Iddo Drori, Yamuna Krishnamurthy, Remi Rampin +5
We introduce AlphaD3M, an automatic machine learning (AutoML) system based on meta reinforcement learning using sequence models with self play. AlphaD3M is based on edit operations…
DataExposer: Exposing Disconnect between Data and Systems
Sainyam Galhotra, Anna Fariha, Raoni Lourenço +3
As data is a central component of many modern systems, the cause of a system malfunction may reside in the data, and, specifically, particular properties of the data. For example,…
Correlation Sketches for Approximate Join-Correlation Queries
Aécio Santos, Aline Bessa, Fernando Chirigati +2
The increasing availability of structured datasets, from Web tables and open-data portals to enterprise data, opens up opportunities~to enrich analytics and improve machine learnin…
