Introduction

The field of geoscience has amassed a vast amount of data, necessitating the extraction and integration of diverse knowledge from this data to address global change challenges, promote sustainable development, and accelerate scientific discovery. Foundation language models initially learn and integrate knowledge autonomously through self-supervised pre-training on extensive text data. Subsequently, they acquire the capability to solve geoscience problems through instruction tuning. However, when the foundational language models lack sufficient geoscience expertise, instruction tuning with relevant data can lead to the generation of content that is inconsistent with established facts. To improve the model's accuracy and practicality, a robust geoscience foundational language model is urgently needed.

This study uses Mistral-7B-v0.1 as the base model and continues pretraining on a large geoscience corpus. It also incorporates the domain-specific large language model pre-pretraining framework (PreparedLLM) and the "two-stage pre-adaptation pre-training" algorithm to build the geoscience large language model, JiuZhou.

Inference

Below is an example of inference code using JiuZhou-Instruct-v0.2.

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

device = torch.device("cuda:0") if torch.cuda.is_available() else torch.device("cpu")

model_path = "itpossible/JiuZhou-Instruct-v0.2"
tokenizer = AutoTokenizer.from_pretrained(model_path)
model = AutoModelForCausalLM.from_pretrained(model_path, torch_dtype=torch.bfloat16, device_map=device)

text = "What is geoscience?"
messages = [{"role": "user", "content": text}]

inputs = tokenizer.apply_chat_template(messages, return_tensors="pt").to(device)
outputs_id = model.generate(inputs, max_new_tokens=600, do_sample=True)
outputs = tokenizer.batch_decode(outputs_id, skip_special_tokens=True)[0]
print(outputs)

Model Performance

Geoscience Ability

We evaluate the performance of JiuZhou using the GeoBench benchmark.
JiuZhou outperforms GPT-3.5 in objective tasks:

JiuZhou also scores higher than baselines across six criteria in subjective tasks:

### General Ability We evaluate the performance of JiuZhou using three benchmark datasets: C-Eval, CMMLU, and MMLU.
Compared to other variants of Llama and Mistral models, JiuZhou shows outstanding performance:

## Model Training Process ### Training Corpus The corpus consists of 50 million general documents and 3.4 million geoscience-related documents.

### Training Framework We use the JiuZhou-Framework proposed in this study.

### Two-stage Pre-adaptation Pre-training (TSPT) TSPT improves the efficiency of using limited geoscience data and overcomes some of the technical bottlenecks in continual pretraining for LLMs.
The difference between TSPT and single-stage training algorithms:

Comparison of TSPT and one-stage pre-training algorithm performance:

## Model Training Code We use [LLaMA-Factory](https://github.com/hiyouga/LLaMA-Factory) to fine-tune JiuZhou.
