Preliminary System Design for an EDA Assistant
Robert St. Amant, Paul R. Cohen · 1994
This paper gives an overview of the design of aide, the Assistant for Intelligent Data Exploration, which assists humans in the early stages of data analysis. The system adopts a script-based planning approach to automating EDA. Data-directed mechanisms extract simple observations and suggestive indications from the data. Scripted EDA operations are then applied in goal-directed fashion to generate deeper descriptions of the data. Control rules guide the operations, relying on intermediate results for their decisions. The system is mixed-initiative, capable of autonomously pursuing high and low level goals while still allowing the user to guide or override its decisions. The discussion covers representation of data, design of EDA operations, and issues in control.
