Published: March 21, 2024

Abstract Accelerating the discovery of advanced materials is crucial for modern industries, aerospace, biomedicine, and energy. Nevertheless, only a small fraction are currently under experimental investigation within vast chemical space. Materials scientists plagued by time-consuming labor-intensive experiments due to lacking efficient material strategies. Artificial intelligence (AI) has emerged as promising instrument bridge this gap. Although numerous AI toolkits or platforms science have been developed, they suffer from many shortcomings. These include primarily focusing on property prediction being unfriendly programming experience, especially performing poorly with limited data. Here, we developed MLMD, an platform design. It capable effectively discovering novel high-potential properties end-to-end, utilizing model inference, surrogate optimization, even working in situations data scarcity based active learning. Additionally, it integrates analysis, descriptor refactoring, hyper-parameters auto-optimizing, prediction. also provides web-based friendly interface without need can be used anywhere, anytime. MLMD dedicated integration experiment/computation design, accelerate new desired one multiple properties. demonstrates strong power direct various (perovskites, steel, high-entropy alloy, etc). will essential tool facilitate advancement informatics.
