It addresses the gap in modeling materials structures with a platform that delivers access to tasks, datasets, methods, evaluations, and benchmark results. The first release targets virtual screening, inverse design, and molecular simulation, covering 9 datasets for 6 materials types, 56 tasks, and 8 property categories.

Gregoire7 Carla P. Gomes1  \n1 Cornell 2 Northwestern 3 UCB 4 UCLA  \n5 MSR AI4Science 6 Microsoft Quantum 7 Caltech * Equal Contribution  \nAbstract  \nWe introduce M2Hub, a toolkit for advancing machine learning in materials discovery. Machine learning has achieved remarkable progress in modeling molecular structures, especially biomolecules for drug discovery. However, the development of machine learning approaches for modeling materials structures lag behind, which is partly due to the lack of an integrated platform that enables access to diverse tasks for materials discovery. To bridge this gap, M2Hub will enable easy access to materials discovery tasks, datasets, machine learning methods, evaluations, and benchmark results that cover the entire workflow. Specifically, the first release of M2Hub focuses on three key stages in materials discovery: virtual screening, inverse design, and molecular simulation, including 9 datasets that covers 6 types of materials with 56 tasks across 8 types of material properties. We further provide  \n2 synthetic datasets for the purpose of generative tasks on materials. In addition to random data splits, we also provide 3 additional data partitions to reflect the real-world materials discovery scenarios. State-of-the-art machine learning methods (including those are suitable for materials structures but never compared in the literature) are benchmarked on representative tasks. Our codes and library are publicly available at [https://github.com/yuanqidu/M2Hub](https://github.com/yuanqidu/M2Hub).  \n1 Introduction  \nWith the methodological advancements in machine learning, an increasing number of machine learning models have been developed and applied to solve scientific problems, from simulating molecular systems with millions of particles to predicting accurate protein structures Zhang et al.[2018], Jumper et al. [2021] . The primary focus of machine learning in the chemical sciences has remained in the domain of molecular structures,(bio)molecules including small molecules, proteins, RNAs, etc. Atz et al. [2021], Rives et al. [2021], Townshend et al. [2021] . However, materials constitute a large portion of the chemical space which have been significantly less studied, especially in the machine learning community. Among scientific problems, materials discovery plays a vital role in driving innovations and progress across various fields spanning energy, electronics, healthcare, and sustainability Sanchez-Lengeling and Aspuru-Guzik [2018], Gomes et al. [2021] . However, the traditional trial-and-error approach to materials discovery is expensive and time-consuming. Over decades, classical machine learning methods have already been widely applied in assisting materials discovery, Schmidt et al. [2019] yet the impact of machine learning for solid state materials lags behind its efficacy in other areas of chemical science.  \nWitnessing the success of machine learning in solving grand challenges in science Wang et al. [2018], Jumper et al. [2021], one of the key ingredients is the infrastructure that supports the machine learning community to build the machine learning workflow: data preparation/processing, model development, performance evaluation, and model improvement based on the evaluation feedback.
