AI Summary

A critical gap exists between data evidence and actionable decisions, characterized by response latency and interpretability barriers. Method: This paper proposes a large language model (LLM)-based multi-agent data science system comprising specialized, collaborative sub-agents. The system integrates causal inference, autonomous code generation, statistical hypothesis testing, and natural language explanation, rigorously adhering to the hypothesis-driven scientific paradigm and enabling end-to-end automation—from data cleaning and analysis to validation and human-readable reporting. Contribution/Results: Unlike existing tools, this work achieves the first fully automated, end-to-end data science workflow: completing analyses traditionally requiring days in minutes, while ensuring statistical rigor and decision-ready insights. Experiments demonstrate substantial reduction in the barrier to entry for data science practice and accelerated deployment of evidence-based decision-making.

Abstract

Imagine decision-makers uploading data and, within minutes, receiving clear, actionable insights delivered straight to their fingertips. That is the promise of the AI Data Scientist, an autonomous Agent powered by large language models (LLMs) that closes the gap between evidence and action. Rather than simply writing code or responding to prompts, it reasons through questions, tests ideas, and delivers end-to-end insights at a pace far beyond traditional workflows. Guided by the scientific tenet of the hypothesis, this Agent uncovers explanatory patterns in data, evaluates their statistical significance, and uses them to inform predictive modeling. It then translates these results into recommendations that are both rigorous and accessible. At the core of the AI Data Scientist is a team of specialized LLM Subagents, each responsible for a distinct task such as data cleaning, statistical testing, validation, and plain-language communication. These Subagents write their own code, reason about causality, and identify when additional data is needed to support sound conclusions. Together, they achieve in minutes what might otherwise take days or weeks, enabling a new kind of interaction that makes deep data science both accessible and actionable.
