A recent article published in the journal NPJ Computational Materials proposed JARVIS-Leaderboard, an open-source platform designed to enhance the reproducibility of materials design methods. They aimed to cover a variety of categories including artificial intelligence (AI), electronic structure (ES), force-field (FF), quantum computation (QC), and experiments (EXP), and enable users to compare and contribute diverse methods and datasets for materials design. Moreover, JARVIS-Leaderboard is seamlessly integrated with the existing NIST-JARVIS infrastructure, enhancing its accessibility and usability.
The jarvis_populate_data.py scripts generate a benchmark dataset. A user can apply their method, train models, or run experiments on that dataset and prepare a csv.zip, a metadata.json file, and other files in a new folder in the contributions directory. The contributions can be locally checked by the user using jarvis_server.py script. Then the folder can be uploaded to a user’s GitHub account by the automated jarvis_upload.py script involving several GitHub uploading steps. The administrators of the JARVIS-Leaderboard at NIST will verify the contributions and then finally, it will become part of the leaderboard website.

Background
Materials design encompasses a wide range of research areas, requiring approaches that span diverse lengths and time scales. These methods, whether computational or experimental, aim to predict and optimize material properties for various applications. However, the development and validation of these methods encounter numerous challenges. These include a lack of robust reproducibility, the presence of diverse data types, the complexity of data analysis, and the difficulty in comparing different methodologies.
To address these challenges, several benchmarking and leaderboard methods have been developed in the past, but they are often limited to a single modality, a small set of tasks or properties, or a specific field of study. Additionally, they lack flexibility in incorporating new tasks or benchmarks, thus posing barriers to potential contributors. Therefore, there is a pressing need for a comprehensive, user-friendly, and dynamic framework capable of accommodating multiple modalities, a broad spectrum of tasks and properties, and various fields of study.
About the Research
In this paper, the authors developed a web-based novel platform designed to offer a flexible and dynamic framework for materials benchmarking. Integrated seamlessly into the existing NIST-JARVIS infrastructure, which hosts several datasets, tools, applications, and tutorials for materials design, this platform enables users to access, download, and upload data, code, and metadata for various benchmarks and contributions.
Moreover, JARVIS-Leaderboard provides users with tools and notebooks to facilitate the creation of plots and comparisons for all available benchmarks and contributions. With a user-friendly interface, the platform provides a simple and consistent data format, ensuring ease of use. Its website is clear and informative, while its streamlined and automated process for uploading contributions enhances user experience.
The platform encompasses several materials design categories, including AI, ES, FF, QC, and EXP. Under the AI category, the platform supports various types of input data, such as atomistic images, atomic structures, spectra, and text. The ES domain covers multiple approaches, pseudopotentials, software packages, materials, and properties, enabling comparisons against experimental results.
For FF, the framework accommodates various approaches for material property predictions, while in the QC realm, it includes Hamiltonian simulations utilizing different quantum algorithms and circuits. Finally, in the EXP category, the platform adopts an inter-laboratory technique to establish benchmarks.
Research Findings
The researchers successfully populated the platform with over 270 benchmarks and more than 1200 contributions sourced from various methods and channels, having a dataset of over 8 million data points. This comprehensive database provided an up-to-date overview of state-of-the-art methods, facilitating a thorough comparison of their performance, accuracy, and limitations.
Furthermore, the framework enabled the identification and analysis of major challenges and opportunities within different fields, including extrapolation capability, computational cost, methodological improvement, material space exploration, and multi-modal modeling. By addressing these aspects, the authors gained valuable insights into the strengths and limitations of existing methodologies.
In addition, the study illustrated how the new technique could be used to compare AI models for formation energy prediction, ES methods for bandgap prediction, FF methods for bulk modulus prediction, and QC methods for electronic band structure simulation. Furthermore, they showcased its utility in benchmarking EXP methods, such as inter-laboratory measurements of CO2 adsorption in zeolites.
Moreover, the authors engaged in discussions regarding major challenges and open questions in various fields, such as evaluating extrapolation capability, reducing computational costs for higher accuracy ES predictions, identifying areas in material space requiring methodological improvements, making atomistic image analysis quantitative, and developing and benchmarking multi-modal models.
Applications
The platform offers numerous applications and benefits for the materials science community, including:
- Establishing a standardized framework for benchmarking and validating various methods in materials design, encompassing diverse data types and modalities.
- Improving the reproducibility and transparency of materials science research by promoting the utilization of peer-reviewed data, code, and metadata, along with providing tools and scripts for result reproduction.
- Facilitating collaboration and communication among researchers, practitioners, and scientists from diverse fields and backgrounds by enabling the sharing and comparison of data, methodologies, and insights.
- Accelerating the discovery and optimization of materials with technological relevance by furnishing a comprehensive and current overview of the most effective methods and practices for each task and property.
- Identifying and addressing gaps and challenges across different fields by offering a platform for testing and evaluating new concepts and approaches, while highlighting areas where methodological improvement is required.
Conclusion
In summary, the novel benchmarking framework demonstrated effectiveness in validating various methods for materials design across diverse data types. Its user-friendly interface and comprehensive coverage provided an up-to-date overview of state-of-the-art methods in each category, facilitating detailed performance comparisons.
Moving forward, the researchers proposed expanding and updating the platform by incorporating new benchmarks, methods, and contributions alongside introducing new categories and sub-categories. They emphasized the importance of community participation and feedback, inviting users to contribute data, code, and metadata as well as to establish new benchmarks and tasks. This collaborative approach aimed to further enhance the platform's utility and impact in advancing materials design research.
