Scaling Up Text-Centric Visual Instruction Tuning: Constructing a Massive High-Quality Dataset for Advancing Open-Source Multimodal Language Models

Core Concepts

Leveraging the capabilities of advanced closed-source multimodal language models, the authors construct a massive, high-quality dataset (Square-10M) for text-centric visual instruction tuning, enabling their open-source model TextSquare to outperform existing state-of-the-art open-source models and even match or surpass leading closed-source models on various benchmarks.

Abstract

The paper introduces a new approach, termed "Square", for creating a large-scale, high-quality instruction-tuning dataset (Square-10M) for text-centric visual question answering (VQA). The dataset is generated using closed-source multimodal large language models (MLLMs) through a four-step process: Self-Questioning, Answering, Reasoning, and Evaluation.
The authors first collect a diverse set of text-rich images from various public sources, including natural scenes, charts, tables, receipts, books, slides, PDFs, documents, products, and web images. They then apply the Square method to these images, leveraging the capabilities of advanced closed-source MLLMs to generate high-quality VQA pairs and reasoning context.
The experiments demonstrate several key findings:

The authors' model, TextSquare, considerably surpasses open-source previous state-of-the-art text-centric MLLMs and sets a new standard on OCRBench (62.2%). It even outperforms top-tier closed-source models like GPT4V and Gemini in 6 out of 10 text-centric benchmarks.
The reasoning data provided in Square-10M is shown to be beneficial in improving model performance and mitigating hallucinations in text-centric VQA scenarios, as it can deliver rich question-specific contextual information.
The authors reveal the relationships between data scale, convergence loss, and model performance for text-centric VQA instruction tuning, demonstrating the effectiveness and necessity of the massive Square-10M dataset.

Deeper Inquiries

How can the Square strategy be further improved to generate even higher-quality instruction tuning data?

The Square strategy can be enhanced in several ways to generate even higher-quality instruction tuning data.

Diversification of Data Sources: Expanding the sources of text-rich images can help capture a wider range of scenarios and improve the diversity of the dataset. Including images from specialized domains or niche areas can enrich the dataset and make it more comprehensive.

Fine-tuning Prompting Techniques: Refining the prompting techniques used in the Self-Questioning and Answering stages can lead to more precise and contextually relevant questions and answers. Experimenting with different prompting strategies, such as multi-step prompting or adversarial prompting, can enhance the quality of the generated data.

Enhanced Reasoning Context: Strengthening the reasoning component by providing more detailed and nuanced explanations for the answers can improve the overall quality of the dataset. Encouraging the model to delve deeper into the rationale behind its responses can lead to more accurate and informative data.

Iterative Filtering Mechanisms: Implementing iterative filtering mechanisms during the Data Filtering stage can help refine the dataset further. By continuously evaluating and refining the generated data based on feedback loops, the dataset quality can be continuously improved.

Human-in-the-Loop Validation: Incorporating human-in-the-loop validation processes can add an extra layer of quality control. Human annotators can review and validate the generated questions, answers, and reasoning, ensuring that the dataset meets high standards of accuracy and relevance.

What are the potential limitations of relying on closed-source models to generate training data, and how can these be addressed?

Relying solely on closed-source models to generate training data can pose several limitations:

Lack of Transparency: Closed-source models may not provide visibility into the underlying processes and mechanisms used to generate the data. This lack of transparency can hinder the reproducibility and interpretability of the generated dataset.

Dependency on Model Performance: The quality of the generated data is directly tied to the performance of the closed-source model. If the model has limitations or biases, these may be reflected in the training data, impacting the performance of downstream models.

Limited Customization: Closed-source models may not offer the flexibility to customize the data generation process according to specific requirements or domain-specific nuances. This limitation can restrict the adaptability of the generated dataset to diverse applications.

To address these limitations, it is essential to:

Promote Transparency: Encourage open communication and documentation of the data generation process to enhance transparency and facilitate reproducibility.
Diversify Data Sources: Supplement closed-source data with open-access or domain-specific datasets to ensure a more comprehensive and diverse training dataset.
Validate Data Quality: Implement rigorous validation and quality assurance processes to verify the accuracy, relevance, and fairness of the generated data.
Explore Transfer Learning: Explore transfer learning techniques to fine-tune models on a smaller, open-source dataset before leveraging closed-source models for data generation.

How can the insights from the scaling relationships between data, loss, and performance be applied to other domains beyond text-centric VQA?

The insights from the scaling relationships between data, loss, and performance can be applied to various domains beyond text-centric VQA:
