Plain-Language Brief

Researchers present TOFFEE, a system that generates high-quality data agent trajectories using Monte Carlo Tree Search with adaptive model selection and cross-task prefix reuse. This system aims to help data agents generalize better in unseen data environments and complex analytical tasks across heterogeneous enterprise settings.

What the Document Says

  • The research focuses on data agents, which play a significant role in data-driven decision making.
  • Existing data agents have difficulties adapting to unseen data environments and workflows, especially in diverse business scenarios.
  • There is a growing need for synthesizing data agent trajectories that capture complex analytical workflows for specific data environments.
  • These trajectories can be used for supervised finetuning (SFT) of data agent models or as in-context learning (ICL) demonstrations for general-purpose LLMs.
  • TOFFEE is a system designed to generate scalable trajectory data for complex analytical tasks across heterogeneous environments.
  • TOFFEE uses Monte Carlo Tree Search (MCTS), adaptive model selection, and cross-task prefix reuse.

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.
