Introduction

StructLM, is a series of open-source large language models (LLMs) finetuned for structured knowledge grounding (SKG) tasks. We release 3 models:

7B | StructLM-7B

13B | StructLM-13B

34B | StructLM-34B

Training Data

These models are trained on 🤗 SKGInstruct Dataset, an instruction-tuning dataset containing mixture of 19 SKG tasks combined with 🤗 SlimOrca. Check out the dataset card for more details.

Training Procedure

The models are fine-tuned with CodeLlama-Instruct-hf models as base models. Each model is trained for 3 epochs, and the best checkpoint is selected.

Usage

You can use the models through Huggingface's Transformers library. Check our Github repo for the evaluation code: https://github.com/TIGER-AI-Lab/StructLM

Prompt Format

For this 7B model, the prompt format (different from 13B, 34B) is

[INST] <<SYS>>
You are an AI assistant that specializes in analyzing and reasoning over structured information. You will be given a task, optionally with some structured knowledge input. Your answer must strictly adhere to the output format, if specified.
<</SYS>>
{instruction} [/INST]

To see concrete examples of this linearization, you can directly reference the 🤗 SKGInstruct Dataset (coming soon). We will provide code for linearizing this data shortly.

A few examples:

Example input

[INST] <<SYS>>
You are an AI assistant that specializes in analyzing and reasoning over structured information. You will be given a task, optionally with some structured knowledge input. Your answer must strictly adhere to the output format, if specified.
<</SYS>>

Use the information in the following table to solve the problem, choose between the choices if they are provided. table:

col : day | kilometers row 1 : tuesday | 0 row 2 : wednesday | 0 row 3 : thursday | 4 row 4 : friday | 0 row 5 : saturday | 0


question:

Allie kept track of how many kilometers she walked during the past 5 days. What is the range of the numbers? [/INST]

Intended Uses

These models are trained for research purposes. They are designed to be proficient in interpreting linearized structured input. Downstream uses can potentially include various applications requiring the interpretation of structured data.

Limitations

While we've tried to build an SKG-specialized model capable of generalizing, we have shown that this is a challenging domain, and it may lack performance characteristics that allow it to be directly used in chat or other applications.
