Data-Juicer Sandbox: A Feedback-Driven Suite for Multimodal Data-Model Co-development (2407.11784v3)

Abstract: The emergence of multimodal large models has advanced artificial intelligence, introducing unprecedented levels of performance and functionality. However, optimizing these models remains challenging due to historically isolated paths of model-centric and data-centric developments, leading to suboptimal outcomes and inefficient resource utilization. In response, we present a new sandbox suite tailored for integrated data-model co-development. This sandbox provides a feedback-driven experimental platform, enabling cost-effective iteration and guided refinement of both data and models. Our proposed ``Probe-Analyze-Refine'' workflow, validated through practical use cases on multimodal tasks such as image-text pre-training with CLIP, image-to-text generation with LLaVA-like models, and text-to-video generation with DiT-based models, yields transferable and notable performance boosts, such as topping the VBench leaderboard. A comprehensive set of over 100 experiments demonstrated the suite's usability and extensibility, while also uncovering insights into the interplay between data quality, diversity, model behavior, and computational costs. All codes, datasets, and models are open-sourced to foster future research and applications that would otherwise be infeasible due to the lack of a dedicated co-development infrastructure.

• The paper introduces a novel sandbox suite that enables integrated co-development of multimodal data and generative models using a Probe-Analyze-Refine workflow.
• It demonstrates significant performance gains in image-to-text and text-to-video generation by leveraging single- and multi-operator data pools alongside a hierarchical data pyramid strategy.
• The framework streamlines resource-efficient iterative improvements and opens new avenues for scalable multimodal AI research and enhanced model training methodologies.

Data-Juicer Sandbox: A Comprehensive Suite for Multimodal Data-Model Co-development

The paper "Data-Juicer Sandbox: A Comprehensive Suite for Multimodal Data-Model Co-development" by Daoyuan Chen et al. introduces a novel open-source sandbox suite aimed at facilitating the integrated development of multimodal data and generative models. This submission targets a pervasive issue in the advancement of multimodal AI: the traditionally isolated development paths for models and data that impede optimal resource utilization and performance enhancement.

Overview of the Data-Juicer Sandbox

The authors present a sandbox suite which serves as an experimental platform for the co-development of multimodal data and generative models, allowing for rapid iteration and refinement. Central to this suite is its "Probe-Analyze-Refine" workflow, validated through applications to models, including those inspired by LLaVA and DiT. The workflow produces significant performance gains, corroborated by superior standings on the VBench leaderboard.

Key Components and Workflows

The sandbox leverages the Data-Juicer system for its plethora of multimodal data processing operators, encapsulating capabilities for filtering, modifying, data analysis, and evaluation. Notably, these components are streamlined under a unified architecture, enabling flexible orchestration of end-to-end workflows, specific development behaviors, and underlying development capabilities.

1. Single-Operator Data Pools: Initial experiments within the sandbox involve single-operator data pools, categorizing data based on metrics such as image aesthetics and text complexity. These provide controlled environments for probing the effects of individual data characteristics on model training.
2. Multi-Operator Data Pools: Building upon insights from single-operator experiments, the sandbox allows for combinatorial testing of multiple operators, examining synergistic or antagonistic interactions to identify optimal data recipes.
3. Data Pyramid Approach: To address the intrinsic trade-offs between data quality and quantity, the authors propose a hierarchical data pyramid strategy, balancing high-quality data reuse against the incorporation of more diverse, albeit lower-quality data.

Experimental Evaluations and Results

The paper substantiates its methodology through rigorous experiments in two domains: image-to-text and text-to-video generation.

Image-to-Text Generation

The authors leverage Mini-Gemini-2B for image-to-text experiments. They identify that:

• High image-text similarity scores and image aesthetics significantly enhance model performance.
• Diverse and high-quality images preferentially boost capabilities when training data aligns closely with the vision tower's configuration parameters.

Text-to-Video Generation

Using EasyAnimate for text-to-video, the paper highlights that:

• Video data quality, influenced by factors such as NSFW scores and frame-text similarity, critically impacts model outputs.
• Extensive data reuse during training results in performance improvements, underscoring data quality's primacy over mere volume.

Implications and Future Directions

The research underscores the imperative for systematic data and model co-development in optimizing multimodal generative AI. By providing a granular, empirically-backed co-development framework, the Data-Juicer Sandbox bridges a significant gap, fostering deeper insights and facilitating scalable, resource-efficient developments.

Implications extend both practically and theoretically. Practically, the sandbox reduces development costs and accelerates exploratory phases by integrating pre-configured, customizable workflows. Theoretically, it opens avenues for more nuanced studies on the interplay of data characteristics and model behavior, paving the way for advancements in model training methodologies and data quality evaluation.

Speculative Future Developments

The capabilities demonstrated by the Data-Juicer Sandbox suggest several avenues for future enhancements:

1. Extended Model Compatibility: Broaden the sandbox's compatibility to include a wider array of multimodal generative models, ensuring higher generalizability across different AI applications.
2. Integrated Ethical Considerations: Incorporate modules that assess and mitigate the ethical impact of data models, ensuring that the generated content aligns with socially responsible AI guidelines.
3. Augmented Intelligence (AI) Data Generation: Explore the use of advanced generative models themselves to augment training datasets, potentially leading to recursive improvements in data quality and model performance.

Concluding Remarks

The introduction of the Data-Juicer Sandbox marks a significant step forward in the systematic co-development of multimodal data and generative models. By integrating comprehensive data processing capabilities and flexible development workflows, it optimizes the synergy between data and models, ultimately enhancing performance while ensuring resource efficiency. As this suite evolves, it is poised to drive substantial progress in multimodal AI research and application.
