Overview

We propose Explore-Instruct, a novel approach to enhancing domain-specific instruction coverage. We posit that the domain space is inherently structured akin to a tree, reminiscent of cognitive science ontologies. Drawing from the essence of classical search algorithms and incorporating the power of LLMs, Explore-Instruct is conceived to actively traverse the domain space and generate instruction-tuning data, not necessitating a predefined tree structure. Specifically, Explore-Instruct employs two strategic operations: lookahead and backtracking exploration:

• Lookahead delves into a multitude of potential fine-grained sub-tasks, thereby mapping out a complex network of tasks

• Backtracking seeks alternative branches to widen the search boundary, hence extending the domain spectrum.

Data Release

We release the Explore-Instruct data in brainstorming, rewriting, and math domains on 🤗 Huggingface Datasets. Each domain includes two versions of datasets: the basic and extended version. The base version contains 10k instruction-tuning data and the extended version contains 16k, 32k, and 64k instruction-tuning data for each domain respectively. Each dataset is a structured data file in the JSON format. It consists of a list of dictionaries, with each dictionary containing the following fields:

• instruction: str, describes the task the model should perform.
• input: str, optional context or input for the task.
• output: str, ground-truth output text for the task and input text.

The results of data-centric analysis are shown as follows:

Model Release

We release the Explore-LM models in brainstorming, rewriting, and math domains on 🤗 Huggingface Models. Each domain includes two versions of models: the basic and extended version trained with the corresponding version of dataset.

The results of automatic and human evaluation in three domains are shown as follows:

Limitations

Explore-Instruct is still under development and needs a lot of improvements. We acknowledge that our work focuses on the enhancement of domain-specific instruction coverage and does not address other aspects of instruction-tuning, such as the generation of complex and challenging instructions or the mitigation of toxic and harmful instructions. Future work is needed to explore the potential of our approach in these areas.
