背景与挑战

背景概述

MAmmoTH-VL-Instruct is a large-scale multimodal instruction-tuning dataset designed to enhance the reasoning capabilities of multimodal large language models (MLLMs). Developed by researchers from Carnegie Mellon University, M-A-P, Nanyang Technological University, University of Waterloo, and The University of Manchester, the dataset was created to address the limitations of existing instruction-tuning datasets, which often repurpose simplistic academic datasets like VQA, AI2D, and ChartQA. These datasets typically provide phrase-level answers without intermediate rationales, failing to elicit deliberate reasoning from MLLMs. MAmmoTH-VL-Instruct aims to bridge this gap by offering a scalable and cost-effective method to construct a dataset with rich intermediate rationales designed to elicit chain-of-thought (CoT) reasoning. The dataset comprises 12 million instruction-response pairs, covering diverse, reasoning-intensive tasks with detailed and faithful rationales.

当前挑战

The primary challenge associated with MAmmoTH-VL-Instruct lies in ensuring the diversity and complexity of instructions while generating coherent responses with detailed rationales. Human-annotated CoT responses, while ideal, are prohibitively costly and lack scalability. Additionally, reliance on proprietary tools like GPT-4 for high-quality data generation involves substantial costs and licensing issues, further exacerbating these challenges. The dataset creation process also faces obstacles in maintaining instruction diversity and complexity, and in generating coherent responses with detailed rationales. The methodology introduced by the researchers involves a three-step pipeline: collecting and categorizing diverse image data into task-specific categories, augmenting and rewriting tasks with CoT-style rationales using open models, and rigorously filtering the data to ensure coherence and accuracy while minimizing hallucinations.
