mCoT: Multilingual Instruction Tuning for Reasoning Consistency in Language Models

Paper: https://arxiv.org/abs/2406.02301

Code: https://github.com/laihuiyuan/mCoT

Dataset: https://huggingface.co/datasets/laihuiyuan/mCoT-MATH

Introduction

We introduce mCoT, a 7B parameter model for multilingual math reasoning that achieves impressive multilingual reasoning consistency across multiple languages. Based on Mistral-7B-v0.1, mCoT is trained on mCoT-MATH, the first large-scale multilingual math CoT reasoning dataset containing around 6.3 million samples for 11 diverse languages.
