Plain-Language Brief

The paper introduces TOFFEE, a system designed to generate high-quality data agent trajectories using Monte Carlo Tree Search (MCTS) with adaptive model selection and cross-task prefix reuse. This is aimed at addressing the challenge of existing data agents struggling to generalize to unseen data environments in heterogeneous enterprise settings.

What the Document Says

  • The text discusses the role of LLM-powered data agents in data-driven decision making.
  • It highlights a problem with existing data agents: their inability to adapt to unseen data environments and analytical workflows, particularly in heterogeneous enterprise settings.
  • The need for synthesizing high-quality data agent trajectories that can capture complex analytical workflows for given data environments is emphasized.
  • These trajectories are meant to serve as supervised finetuning (SFT) data and as in-context learning (ICL) demonstrations.
  • The paper presents TOFFEE, a system for synthesizing high-quality data agent trajectories from given data environments via Monte Carlo Tree Search (MCTS) with adaptive model selection and cross-task prefix reuse.
  • It is claimed that TOFFEE can effectively generate scalable trajectory data for complex analytical tasks across heterogeneous environments.
  • The paper discusses the system framework of TOFFEE, including its task pool construction, trajectory explorer, and learned cost model.

Notes for Future Q&A

May include interpretation. Labeled where it does.

  • The paper does not provide specific numerical results, so it's hard to directly compare the performance of TOFFEE with other methods.
  • Further research is needed to understand how the quality of synthesized trajectories is determined and whether they truly capture complex analytical workflows.

Raw Abstract / Excerpt

LLM-powered data agents are playing an increasingly important role in data-driven decision making. However, existing data agents struggle to generalize to unseen data environments and analytical workflows, especially in heterogeneous enterprise settings. This creates a growing need for synthesizing high-quality data agent trajectories that capture complex analytical workflows for given data environments. Such trajectories support two key downstream uses: they can serve as supervised finetuning (SFT) data that adapts data agent models to the target domain, and as in-context learning (ICL) demonstrations to guide general-purpose LLMs in unfamiliar data environments. Thus, we introduce TOFFEE, a system for synthesizing high-quality data agent trajectories from given data environments via Monte Carlo Tree Search (MCTS) with adaptive model selection and cross-task prefix reuse. We show that TOFFEE can effectively generate scalable trajectory data for complex analytical tasks across heterogeneous environments. In this demonstration, we present the system framework of TOFFEE, including its task pool construction, trajectory explorer, and learned cost model. We also introduce the web interface of TOFFEE and its workflow, and demonstrate two end-to-end scenarios: trajectory synthesis for data agent finetuning, and demonstration-augmented data agent reasoning.
